OFFSETS

MENU → SETTINGS → OFFSETS
TEMPERATURE OFFSETS
This option allows calibration (or deliberate miscalibration) of the room temperature sensor(s). There are various reasons why the displayed temperature would be adjusted to a higher or lower value. NOTE: Do not adjust for 30 minutes after installation because the board may be heated by handling. The selected number is the number of degrees, plus or minus, which will be added to the actual temperature. The numbers can range between -5° and +5°. Default values are set to 0° offset.

Temperature Offset
Remote Indoor Offset (if the sensor is attached) Outdoor Offset (if the sensor is attached)

HUMIDITY OFFSET
This option allows the calibration of the humidity sensor. Adjustments can range between -10% and +10%. The default is 0% offset.

AUTO CHANGEOVER
With the auto changeover, the thermostat automatically switches itself from heating to cooling, or vice versa, based on the setpoints. When setting up the thermostat you have to enter both a cooling setpoint and a heating setpoint. The thermostat will also prevent the user from setting the cooling setpoint lower than the heating setpoint. The mode is set to AUTO for this operation to work.

MENU → SETTINGS → AUTO CHANGEOVER
Auto Changeover Time – This setting sets the minimum off time before the thermostat can change from one mode to another. The default is 5 minutes. The range is from 0-120 minutes in 15-minute increments.
Auto or Manual Change – Default is AUTO. If MANUAL is chosen, you will need to change from heating to cooling or vice versa. When MANUAL is set, AUTO is removed from the MODE screen as a choice.

INTERMITTENT FAN
Temperature conditions can vary widely between the thermostat location and extremities of the space the thermostat serves. This air stratification problem can be especially pronounced during mild outdoor conditions when long periods elapse between space conditioning demands from the thermostat. This intermittent fan operation can also improve the performance of air cleaning or special filtration systems that locate the cleaning or filtration media at the return air side of the fan.

1. MENU → SETTINGS → INTERMITTENT FAN
2. If the FAN hasn’t been on for an hour, the fan will start cycling based on these times. The default is OFF. The first screen is the amount of time you want the fan to be energized. Ranges are OFF, or 5-20 minutes in 5-minute increments.
3. After entering this time and pressing the center button ■, the next screen is the amount of time the fan is OFF. Ranges are 0 minutes or 5-40 minutes in 5-minute increments.
4. After entering this time and pressing the center button ■ you will be returned to the Setting Menu screen.
5.  Fan ON and OFF cycles will continue until the fan has been energized by a call for heating or cooling.

INSTALLER

INFORMATION / ADVANCED FEATURES
SAFETY CONSIDERATIONS
Improper wiring or installation may damage a thermostat. Wiring must conform to local and national electrical codes

INTRODUCTION
The thermostat is a wall-mounted, low-voltage thermostat that maintains room temperature by controlling the operation of a heating and air conditioning system. Batteries are not required; temperature and mode settings are preserved with the power off.

INSTALLATION CONSIDERATIONS
The thermostat requires no batteries. The thermostat is not a power-stealing device and MUST have both R and C connected.

INSTALLATION

THERMOSTAT LOCATION
The thermostat should be mounted:

• Approximately 5 ft. (1.5m) from the floor.
• Close to or in a frequently used room, preferably inside On a section of wall without pipes or ductwork.
  The thermostat should NOT be mounted:
  • Close to a window, on an outside wall, or next to a door leading to the outside.
  • Exposed to direct light and heat from a lamp, sun, fireplace, or another temperature-radiating object which may cause a false reading.
  • Close to or in direct airflow from supply registers and return-air grilles.
  • In areas with poor air circulation, such as behind a door or in an alcove.

INSTALL THERMOSTAT

1. Turn off all power to the unit.
2. If an existing thermostat is being replaced:
   •  Remove the existing thermostat from the wall.
   • Disconnect wires from the existing thermostat, one at a time. Be careful not to allow wires to fall back into the wall.
   • As each wire is disconnected, record the wire color and terminal marking.
   • Discard or recycle old thermostats.
   • NOTE: Mercury is a hazardous waste and MUST be disposed of properly.
3. Separate the front and back pieces of plastic.
4. Route thermostat wires through holes in the back piece of plastic. Level plastic against the wall (for aesthetic value only – thermostat need not be leveled for proper operation) and mark the wall through 2 mounting holes.
5. Drill two 3/16-in. mounting holes in the wall where marked. (Note: Mounting holes on the thermostat are designed to fit on a horizontal J-box).
6. secure the back plastic to the wall with 2 anchors and screws provided making sure all wires extend through the hole in the plastic.
7. Connect wires to the proper terminal of the connector block in the front plastic.
8. Push any excess wire back into the wall. The excess wire inside the thermostat plastic case can interfere with proper airflow across the temperature sensor. Seal the hole in the wall to prevent air leaks. Leaks can affect operations.
9. Snap front and back pieces of plastic together.
10. Turn on the power to the unit

WIRING DIAGRAMS

MENU → SETTINGS → CYCLES PER HOUR
PROGRAM SETTINGS

1. MENU → SETTINGS → PROGRAM SETTINGS

SMART RECOVERY
Smart recovery is a feature of your thermostat designed to improve comfort by adjusting temperatures to achieve a room temperature by the programmed time. When it’s time for a programmed
temperature change, smart recovery begins working in advance, turning the system on and off as needed to adjust the indoor temperature. During these transition periods, you may notice that the actual temperature and your temperature setting don’t match. That’s a smart recovery in action, adjusting temperatures in small increments for greater energy efficiency. This is more energy efficient than simply allowing the system to operate at full capacity until the desired temperature has been met. Smart Recovery helps avoid excessive use of auxiliary heat when recovering from night setbacks in the heating mode.

EVENTS PER DAY

This is where you can set the number of events per day. (An event is a period of time scheduled with a certain heating and cooling setpoint.) For instance, if you are away from your home from 8 am to 5 pm, make this period of time an event and set the thermostat at an energy-saving setting. You have the option of setting the events per day to 4-RESIDENTIAL (4 events), 2-RESIDENTIAL (2 events) or 2-BUSINESS (2 events).

SMART HEAT STAGING (HEAT PUMP ONLY)
This delays 3rd stage heating for a set time. Options are ON or OFF. The default is OFF. The range for this is 0-120 minutes in 5-minute increments. If set to ON, 30 minutes is the default time.( If ‘ON’ is selected and the demand has not been satisfied the thermostat will energize electric heat after the selected time has expired regardless of demand.)

COOLING LOCKOUT
When an outdoor temperature sensor is installed, it can be set up so the cooling option doesn’t energize if the outdoor temperature is below a certain temperature. Ranges for this are NONE (default), 45°F, 50°F, or 55°F.

ELECTRIC HEAT or Dual Fuel LOCKOUT
When an outdoor temperature sensor is installed, you can set it up so the electric heat or Dual Fuel option doesn’t energize if the outdoor temperature is above a certain temperature. Ranges for this are NONE (default), 5°F to 60°F in 5° increments.

COMPRESSOR SATISFY
Normal – allows compressor downstaging from Y2 to Y1. Recommended setting for Envision series products.
Y2 Finish – Once the heat pump has engaged Y2 the thermostat will not allow downstaging to Y1. The call is satisfied in Y2.

REMOTE SENSOR
Allows selection of the remote sensor to determine indoor temperature. Options are REMOTE SENSOR, AVERAGE, and STAND ALONE. The REMOTE SENSOR is connected to the ID and GND on the thermostat terminals.

Safety Warnings

CAUTION Follow Installation Instructions carefully.
DISCONNECT POWER TO THE HEATER – AIR CONDITIONER BEFORE REMOVING THE OLD THERMOSTAT AND INSTALLING THE NEW THERMOSTAT.

CAUTION
The two Alkaline “AA” batteries must be replaced at least once every 12 months to ensure proper operation. The Low Battery icon (fig. 1) will appear on the display when it is time to replace the batteries. If the thermostat is connected to 24v power, the batteries should still be installed, but are not required.

When battry is displayed the batteries must be replaced immediately. The manufacturer cannot be liable for improper operation of the thermostat if the batteries are not immediately replaced.
Annual battery replacement is especially critical in locations subject to freezing temperatures. The thermostat will be unable to turn on the heating system if the batteries are exhausted.

Preparation

• Proper installation of the thermostat will be accomplished by following these step-by-step instructions. If you are unsure about any of these steps, call a qualified technician for assistance.
• These tools will be required:
• Make sure your Heater/Air Conditioner is working properly before beginning the installation of the thermostat.
• Carefully unpack the thermostat. Save the screws and instructions.
• Turn off the power to the Heating/Air Conditioning system at the main fuse panel. Most residential systems have a separate breaker for disconnecting power to the furnace.

Remove & Replace Old Thermostat

• Remove the cover of the old thermostat. If it does not come off easily check for screws.
• Loosen the screws holding the thermostat base or subbase to the wall, and lift away.
• Disconnect the wires from the old thermostat. Tape the ends of the wires as you disconnect them, and mark them with the letter of the terminal for easy reconnection to the new thermostat.
• Keep the old thermostat for reference purposes, until your new thermostat is functioning properly.

Battery Replacement

1. The batteries are easily accessible from the battery slot located on the front of the thermostat (fig. 1). To open the battery slot, press down on the battery cover
   (fig. 1) and pull out (fig. 2).
2. Remove the old batteries and replace with the new AA alkaline batteries (fig. 3).
3. Place the bottom hook of the battery cover into the slot and snap closed (fig. 4).

The batteries must be replaced immediately when the thermostat displays the low battery icon (fig. 1). If the thermostat is connected to 24v power, the batteries should
still be installed. Installing the batteries when the system is powered (24VAC) will keep the clock running in the event of line power interruption.

Installing the Outdoor Sensor

The Outdoor Sensor measures outdoor air temperature and sends this information to the thermostat; it measures temperature with a range of -40 to 127 F.
The Outdoor Sensor should be connected to the thermostat using solid conductor CAT 5, CAT 5e, or CAT 6 type network communication cable. This is an unshielded cable with four twisted pairs of 24 gauge solid wire; DO NOT use stranded cable. The cable length should not exceed 250 feet. If less than 75 feet of cable is required to connect the thermostat to the Remote Sensor, a three conductor thermostat cable (18-24 gauge) may be used; this cable is NOT suitable for any length greater than 75 feet.
IMPORTANT: Do no use shielded wire. Do not run sensor wiring in the same conduit as the 24VAC thermostat wiring. Electrical interference may cause the sensor to give incorrect temperature readings. See the Outdoor Sensor accessory for further details.

SECTION 5 Test Operation

Overview

ColorTouch thermostats support the handling of specific signals from the utility provider. The utility-generated signals carry pricing information and/or setback actions that alter the comfort settings of the thermostat in order to reduce energy usage on demand. This is known as Automated Demand Response or ADR for short. You must register to participate in a utility-sponsored program, if offered by your local utility, to take advantage of this feature.

SKYPORT CLOUD SERVICES
From the web application, the user will select Thermostat Settings from the left column. Then the Demand Response button is selected.

The Demand Response configuration page, shown below, is where the thermostat is configured to respond to the energy provider’s signals. It also sets operational parameters for the thermostat. The left column of the ADR configuration page allows or prevents access by the utility. Here communication with the utility and your thermostat may be turned On or Off.
The selected utility will provide a Program ID. The Account ID would normally be the occupant’s utility account number.

The right column of the ADR configuration page is where the occupant adjusts the operational parameters for ADR. The utility may send up to 3 types of ADR signals to Skyport. These are:

1.  Pricing for the cost of energy, 2) An Offset to the occupants’ comfort setpoints, and 3) a signal to enforce discrete or Static setpoints. The Maximum Cooling Setpoint and Minimum Heating Setpoints for ADR events are adjusted here. The Static Settings are applied when the utility sends a signal to allow the occupant to enforce their own discrete temperature settings during an ADR event.
2. The Offset Settings allow the utility to modify the Cool or Heat setpoints by the value set here during an ADR event. A Price Trigger setting allows the occupant to set the maximum cost of energy threshold. When this threshold is exceeded the Price dependent action is enforced. This Price Trigger and Dependent action is enforced independent of an ADR event, as long as the utility sends ‘real-time’ pricing.

Selecting the Overview tab of the ADR page will cause a summary of ADR events to be displayed.

Automated Demand Response
Utility and Program setup must be done at the Skyport Cloud Services account. From the thermostat Home Screen, press the ‘Menu’ button, then select ‘Settings”.

By selecting ADR – On, the user can participate in ADR events triggered by their utility, or price-dependent events.

In the above example; if the price threshold is exceeded, the thermostat will invoke the ‘Offset Setpoints’ configured for an ADR event until the event is over. Please note that the Threshold price may only be set in the Skyport Cloud Services account. Selecting ‘Skip Event’ will take no action when the set price threshold is exceeded.

Remove and Replace the old thermostat

To install the thermostat properly, please follow these step-by-step instructions. If you are unsure about any of these steps, call a qualified technician for assistance.

• Assemble tools: Flat blade screwdriver, wire cutters, and wire strippers.
• Make sure your Heater/Air Conditioner is working properly before beginning the installation of the thermostat.
• Carefully unpack the thermostat. Save the screws, any brackets, and instructions.
• Turn off the power to the Heating/Air Conditioning system at the main fuse panel. Most systems have a separate breaker for disconnecting power to the furnace.
• Remove the cover of the old thermostat. If it does not come off easily, check for screws.
• Loosen the screws holding the thermostat base or subbase to the wall and lift away.
• If you have a smartphone handy, take a photo of the wiring for future reference.
• Disconnect the wires from the old thermostat. Tape the ends of the wires as you disconnect them, and mark them with the letter of the terminal for easy reconnection to the new thermostat.
• Keep the old thermostat for reference purposes, until your new thermostat is functioning properly.

Wire Connections
If the terminal designations on your old thermostat do not match those on the new thermostat, refer to the chart below or the wiring diagrams that follow.

Wire from the old thermostat terminal marked	Function	Install on the new thermostat connector marked
G or F	Fan	G
Y1, Y	Cooling	Y1
W1, W	Heating	W1/0/B
Rh, R, M, Vr, A	Power	R
C	Common	C
O/B	Rev. Valve	W1/O/B*
W2	2nd Stage Heat	W2
Y2	2nd Stage Cooling	Y2
W3	3rd Stage Heat	W3
OUT –	Outdoor Sensor	SENSOR
OUT +	Outdoor Sensor	SENSOR

O/B is used if your system is a Heat Pump. Before you go any further, determine what your existing wiring and equipment situation is.

• If you have a Heating only system without Air Conditioning, the Venstar thermostat will require 3 wires: R (24Vac), C (24Vac) and
  W (Heat). Most systems that only have Heating use very simple thermostats that require 2 wires: the R (24Vac) and W (Heat). The Venstar thermostat requires 3 wires to the thermostat. In this case an Add-a-Wire accessory will not work and it will be necessary to install another wire for the C (24Vac) connection.
• If you have a single-stage fossil fuel heater with air conditioning, the Venstar model will require 5 wires for independent fan control. They are R (24Vac), C (24Vac), W (Heat), Y (Cooling), and G (Fan). You may connect only 4 wires, as instructed in the “Making 4 Wires Work When 5 Wires Are Required” section on page 75.
  If there are only 4 wires present that are connected to the existing thermostat, there are at least 3 options available to connect the Venstar thermostat:
  1. Use the 4 wires as instructed in the“Making 4 Wires Work When 5 Wires Are Required” section on page 75, and note that the fan will only operate with a Heating or Cooling demand.
  2. Pull new thermostat wire from the HVAC equipment to the thermostat so that there are at least 5 wires available.
  3. Purchase and install a Venstar Add-A-Wire accessory.
• If you have a multi-stage HVAC system comprised of a fossil fuel heater with air conditioning, the Venstar thermostat will require the 5 wires mentioned above (R, C, W, Y, G) plus an additional wire for each additional stage of Heating or Cooling. You may reduce the 5 wire requirement to 4 if you give up independent fan control following the instruction in the “Making 4 Wires Work When 5 Wires Are Required” section on page 75, or use the optional Add-A-Wire accessory.
• if you have a heat pump without aux heat, the Venstar model will require 5 wires: R (24Vac), C (24Vac), W1/O/B (Reversing Value), Y (1st Stage Compressor), and G (Fan).
  If you are short 1 wire, there are at least 3 options available to connect the Venstar thermostat:
  1.  Use the available wires as instructed in the“Making 4 Wires Work When 5 Wires Are Required” section on page 75 and note that the fan will only operate with a Heating or Cooling demand.
  2. Pull new thermostat wire from the HVAC equipment to the thermostat so that there are at least 5 wires available.
  3. Purchase and install a Venstar Add-A-Wire accessory.
• If you have a heat pump with aux heat, the Venstar model will require 6 wires: R (24Vac), C (24Vac), W1/O/B (Reversing Value), Y (1st Stage Compressor), W2 (Aux Heat), and G (Fan). If you are short 1 wire, there are at least 3 options available to connect the Venstar thermostat:
  1.  Use the available wires as instructed in the“Making 5 Wires Work When 6 Wires Are Required” section on page 76 and note that the fan will only operate with a Heating or Cooling demand.
  2.  Pull new thermostat wire from the HVAC equipment to the thermostat so that there are at least 6 wires available.
  3. Purchase and install a Venstar Add-A-Wire accessory.

Making 4 Wires Work When 5 Wires Are Required

If you would like to install the Venstar thermostat using only 4 wires when 5 are required, follow the directions below. You will need a screwdriver along with a 3″ long piece of thermostat wire to use as a jumper:

1. Make sure the power is off.
2. Label and disconnect wires at the thermostat. Please note the color and corresponding wire designator with each color. For example, The R wire is red and the W wire is white and so on. You will need this information handy for the next step at the HVAC equipment.
3. At the HVAC equipment end of the thermostat wires (usually at the furnace), locate the terminals that the wires are attached to.
4. Remove the “G wire” from the terminal marked G.
5. Place the “G wire” on terminal C.
6. Place one end of the 3″ long jumper on terminal G.
7. Place the other end of the 3″ long jumper on terminal Y. Please note that there will be more than 1 wire on terminal Y.
8. When connecting the wires to the Venstar thermostat, note that the wire that was previously connected to the G terminal of the old thermostat will now be required to be connected to the C terminal on the Venstar thermostat. All other wires will be connected such that the connections on each end of the individual wires match terminal designations. For example:
9. Connect the yellow wire on the thermostat end to the Y terminal on the thermostat. The yellow wire will be connected to the Y terminal on the HVAC equipment end also.

Making 5 Wires Work When 6 Wires Are Required
If you have a system that requires 6 wires, and you would like to install the Venstar thermostat using only 5 wires, follow the directions below. You will need a screwdriver along with a 3″ long piece of thermostat wire to use as a jumper:

1. Make sure the power is off.
2. Label and disconnect wires at the thermostat. Please note the color and corresponding wire designator with each color. For example: The R wire is red and the W wire is white and so on. You will need this information handy for the next step at the HVAC equipment.
3. At the HVAC equipment end of the thermostat wires (usually at the furnace), locate the terminals that the wires are attached to.
4. Remove the “G wire” from the terminal marked G.
5. Place the “G wire” on terminal C.
6. Place one end of the 3″ long jumper on terminal G.
7. Place the other end of the 3″ long jumper on terminal Y. Please note that there will be more than 1 wire on terminal Y.
8.  When connecting the wires to the Venstar thermostat, note that the wire that was previously connected to the G terminal of the old thermostat will now be required to be connected to the C terminal on the Venstar thermostat. All other wires will be connected such that the connections on each end of the individual wires match terminal designations. For example: Connect the yellow wire on the thermostat end to the Y terminal on the thermostat. The yellow wire will be connected to the Y terminal on the HVAC equipment end also.

The Venstar ColorTouch Backplate

IMPORTANT: This thermostat requires both R (24 VAC Return) and C (24 VAC Common) be connected to the backplate terminals.

Explanation of Thermostat Dip Switches
Dip switches are located on the back of the thermostat

• This dip switch configures the thermostat to control a conventional gas/electric system or a heat pump. If your system is anything other than a heat pump, leave this switch set for GAS/EL.**For some commercial heat pumps, this switch may need to be set for GAS/EL. Consult the commercial heat pump literature.
• When the GAS/EL or HP dip switch is configured for HP, this dip switch (O or B) must be set to control the appropriate reversing valve. If O is chosen, the W1/O/B terminal will energize in cooling. If B is chosen, the W1/O/B terminal will energize in heating.

1. When GAS/EL or HP is set for GAS/EL: This switch (GAS or ELEC) controls how the thermostat will control the Fan (G) terminal in heating mode. When GAS is chosen, the thermostat will not energize the Fan (G) terminal in heating. When ELEC is chosen the thermostat will energize the fan in heating.
2. When GAS/EL or HP is set for HP: This switch (GAS or ELEC) defines the Aux Heat type. When GAS is chosen, the auxiliary heat will not be allowed to run during heat pump operation. When using a Dual Fuel system, set this switch for GAS. When ELEC is chosen, up to two stages of auxiliary strip heat will be allowed to run.

Troubleshooting

• SYMPTOM: The thermostat touchscreen buttons are not responsive. CAUSE: The touchscreen is out of calibration.
  REMEDY: Remove the thermostat from the backplate. Push the thermostat back onto the backplate, while keeping your finger pressed firmly against the center of the touchscreen until the Calibration screen appears. Re-calibrate the touchscreen. See the Touch Calibration section of the full user’s manual (page 23).
• SYMPTOM: The display is blank.
  CAUSE: Lack of proper power.
  REMEDY: Make sure the power is on to the HVAC and that you have 24vac between R & C.
• SYMPTOM: The air conditioning does not attempt to turn on.
  CAUSE: The cooling setpoint is set too high.
  REMEDY: Lower the cooling setpoint or lower the cooling set-point limit. See Setpoint Limits (page 33).
• SYMPTOM: The heating does not attempt to turn on.
  CAUSE: The heating setpoint is set too low.
  REMEDY: Raise the heating setpoint or raise the heating set-point limit. See Setpoint Limits (page 33).
• SYMPTOM: When controlling a residential heat pump, and asking for cooling, the heat comes on.
  CAUSE: The thermostat reversing valve dip switch is set for “B”. REMEDY: Set the reversing valve jumper for “O”.
• SYMPTOM: When calling for cooling, both the heat and cool come on. CAUSE: The thermostat equipment dip switch is configured for “HP” and the HVAC unit is a Gas/Electric.
  REMEDY: Set the equipment dip switch for “Gas”.
• SYMPTOM: Air handler control board fuse blows when the thermostat
  is attached to the backplate with power on, but does not blow until the thermostat is placed onto the backplate.
  CAUSE: The Outdoor sensor and/or sensor wiring is shorted. REMEDY: Check/replace Outdoor sensor and/or sensor wiring.
