EcoNet Smart Thermostat Installation Instructions
The EcoNet System consists of several intelligent, communicating components. Commands, operating conditions, and other data are passed continuously between components. All system components are controlled through the wall mounted EcoNet Smart Thermostat, which replaces the conventional thermostat and provides the homeowner with a single wall control for all features of the system.
Note: Read the entire instruction manual before starting the installation.

Safety Considerations

Failure to read and follow all instructions carefully before installing or operating this control and system could cause personal injury and/or property damage
WARNING: Power off your Heating, Ventilation and Air Conditioning system by using the master switch or circuit breaker box
Note: All wiring must comply with national, local and state codes.

Thermostat Location

The EcoNet Smart Thermostat is the command center for the EcoNet System, as well as the control for the heating and cooling equipment. It should be located where it is easily accessible and visible to the homeowner or end user. For accurate zone temperature and humidity measurement, the following guidelines should be followed

The EcoNet Smart Thermostat should be mounted:

  • Approximately 5 feet (1.5 m) from the floor
  • Close to or in a frequently used room, preferably on an inside wall
    Decide if you want to use the adapter plate with your new EcoNet Smart Thermostat. The adapter plate is useful if you want to hide marks or holes left by your previous thermostat.
    Note: The adapter plate is sold separately. Adapter Plate – RETSTWPL700.

The EcoNet Smart 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 or heat from a lamp, sun, fireplace, or other temperature-radiating objects which could cause a false reading
  • Close to or in direct airflow from supply registers or returns
  • In areas with poor air circulation, such as behind a door or in an alcove
  • On a section of wall with pipes or ductwork

If you are installing with a remote temperature sensor, place your remote sensor at a height of approx. 5 feet (1.5 m) on an interior wall, away from direct heat/cool sources (e.g. fireplace, air vents, etc.)

Wiring Considerations

Ordinary thermostat wire is recommended. Use 18 AWG or larger for normal wiring applications. Wire should be free from defects such as wear, cracks or anything that would hinder the conductivity of the wire within
the circuit.
Note: Wiring only requires four wires. However, it is good practice to run thermostat cable having more than four wires in the event of a damaged or broken wire during installation.
The units should be wired in a “daisy chain” and not in a “star” configuration. To “daisy chain” the units on
the network, each unit should have a set of wires coming into it and one set going out of it except the two communicating devices that are at the ends of the network. The devices on the ends should have only one set of wires to it. The order of the devices in the network is not specified except the EcoNet Smart Thermostat should be at one end of the network.
The EcoNet Smart Thermostat has a six-terminal connector labeled R, C, E1, E2, S1 and S2.

Terminal Function

  • R Power – 24 VAC
  • C Common / Ground – 24 VAC
  • E1 EcoNet Communications Bus Wire 1
  • E2 EcoNet Communications Bus Wire 2
  • S1 (optional) Analog Remote Temperature Sensor Input
  • S2 (optional) Common/Ground – 24 VACECONET-RETST700SYS-Smart-Thermostat-45

Example of Smart Thermostat connection with HVAC and Water Heater unit. Please note this is an example only, and the ordering network can change as long as it is daisy chained.

Electrical Specifications

  • Input Voltage ………… 22 VAC to 26 VAC (24 VAC typical)
  • AC Line Frequency … 50/60 Hz
  • WiFi……………………802.11 b/g/n 2.4 GHz

(OPTIONAL) Shielded Wire
If the thermostat wiring will be located near or in parallel with high voltage wiring, cable TV, Ethernet wiring or radio-frequency equipment, then shielded thermostat wire can be used to reduce or eliminate potential interference. The shield wire should be connected to the C terminal, or ground, at the indoor unit only. The shield wire from all of the thermostat runs should be attached together and only grounded at the indoor unit. The shield wire should NOT be connected to any terminal at the smart thermostat. Connecting the shield to ground at more than one location can cause current loops in the shield, reducing shield effectiveness.

Mounting EcoNet Smart Thermostat

  1. Turn off all power to equipment (e.g. furnace or air handler and outdoor unit).
  2. If an existing thermostat or control is being replaced:
    Remove existing control from wall.
    Disconnect wires from existing control.
  3. Place the provided ferrite toroid around the thermostat wires and nest in the drywall. It is suggested to place a zip tie on the thermostat wire to prevent the ferrite toroid from sliding too far back. (See Fig. 1)
    Note: A ferrite toroid is a magnetic core made of ferromagnetic material. It is used for its properties of high magnetic permeability coupled with low electrical conductivity to help reduce radio frequency emissions that can interfere with other devices.
  4. Position the back plate of your EcoNet Smart Thermostat on your wall, using the built-in level to make sure it’s straight. Mark the mounting holes on your wall in pencil.
  5. Drill mounting holes for the drywall anchors and insert.
    Note: It is recommended you fill the hole around the thermostat wires with light insulation to prevent draft.
  6. Route wires through hole in wall plate plastic. Use the screws provided to secure the back plate to the wall.(See Fig. 2)
  7. Match and connect thermostat wires to proper terminals on back plate. (See Fig. 3)
    Note: the wire color used for each terminal, as it is good practice to use the same wire color on identical termination points on the indoor and outdoor units.
  8. The wires from the wall should plug easily into the terminal blocks. To release a wire, press down on the lever. When installed correctly, the release lever of the terminal block will lower to indicate engagement.
  9. Push any excess wire back into the wall. Seal hole in wall to prevent any air leaks. Leaks can affect operation.
  10. Attach EcoNet Smart Thermostat to the secured wall plate using alignment guides. (See Fig. 4)
  11. Perform installation of all other system equipment.
  12. Turn power to equipment back on.
    Note: To avoid nuisance alarms, power outdoor unit prior to indoor unit.ECONET-RETST700SYS-Smart-Thermostat-46

Wiring Remote Temperature Sensor

The EcoNet Smart Thermostat is optimized to work with the Aprilaire 8051 Temperature Sensor (10K thermistor). Use the S1 and S2 terminals on the wall plate terminal block. Only one remote temperature sensor can be supported.

Menu > Settings > Basic > Room Sensor Selection
You can choose to have the system function based on the temperatures measured by the internal sensor of the thermostat, the remote sensor or the average between the two sensors.

    • Low Airflow: Will increase the first stage Midpoint heat rise +7˚ by lowering the CFM
    • Lowest Airflow: Will increase the first stage Midpoint heat rise +12˚ by lowering the CFM
  • G Input Fan Control – Off (default), Low, Medium Lo, Medium, Medium High, High: airflow to run if the G terminal is activated. To be used for add-on accessories (like ventilators) that are wired to the furnace G terminal and wish to run the blower.

Two auxiliary inputs (AUX1 and AUX2) are provided on the communicating gas furnace control for external control of the system (see the furnace installation instructions for additional details). These inputs can be configured as normally closed or normally open when used in conjunction with the AUX Common. These inputs can be used for field accessories such as smoke detectors, freeze stats, etc. The inputs are configured by the installer
as follows:ECONET-RETST700SYS-Smart-Thermostat-50

AUX Input #1 or 2 Configured – N.O. (Normally Open) or N.C. (Normally Closed): setting to activate the input to the furnace control IFC (see the furnace installation instructions).

  • If Normally Open is selected, when the AUX #1 or 2 input is connected to AUX Com by a closed switch (e.g. drain switch, freeze switch, etc.) the user selected actions will occur.
  • If Normally Closed is selected, when the AUX #1 or 2 input is disconnected to AUX Com by an open switch the user selected actions will occur.

User Selected Action:

  • Off (This is the default setting. These inputs are turned off)
  • Float Switch Alarm (shutdown cooling with an active alarm)
  • Shutdown (This shuts indoor and outdoor units down, no alarm)
  • Shutdown Cool (In cooling mode this shuts down the outdoor unit, no alarm)
  • HP Heat Lockout (In heating mode this shuts down the outdoor unit, no alarm)
  • Furnace Heat Lockout (In heating mode this shuts down the gas furnace, no alarm)

Filter Type
Media, Electronic Air Cleaner (EAC) or both. The filter type selected will drive the air filter service reminder experience.

Fuel Type
Natural gas or propane.
Note: This only adjusts the EcoNet Smart Thermostat’s control settings and does not convert the actual Gas Furnace to operate with Propane. You must use the proper orifice kit for the model Furnace installed.

Elevation
This is the elevation at or above sea level.

Bypass Temp Limit
The maximum temperature for exiting air temperature while the system is bypassing. If the limit is exceeded the system may shutoff and trigger the T027_Z Supply Temp Limit Exceeded to Bypass alert.
The default limits by application are:

  • Furnace 160°F – this can be adjusted down to 100°F
  • Cooling 45°F
  • Heat pump heating 120°F
  • Heat pump with electric heat 135°F

Max Furnace Capacity
Allows reduction of the maximum blower speed. Can be used to reduce the indoor blower airflow. This will also reduce the operating capacity.

How do I connect a ventilator (HRV or ERV) to an EcoNet HVAC system?
One must use the ventilator’s wall control in the traditional manner, except only wire the ventilator control to the G terminal of the furnace (do not wire to the Y or W terminals). In the EcoNet furnace setup menu, change the G Input Fan Control to a fan speed that is desirable to run with the ventilator. The EcoNet system monitors the furnace G terminal, and will turn on the fan when requested by the G terminal signal (when it is not heating or cooling).

AC/HP Settings

AC/HP Settings (Menu > Settings > Installer > AC/HP)
Go to Menu > Settings > Installer (tap and hold) > AC/HP.

Outside Unit Selection
Chooses outdoor unit type:

  • Non-communicating – Allows you to manually enter settings for your outdoor unit. If “non-communicating” outdoor unit is selected, change the type (AC or HP), number of stages (1 or 2) and size (Tons) to match the Outdoor Unit information.
  • EcoNet (locked) – Displays “EcoNet” if a communicating EcoNet Enabled outdoor unit is discovered. The selection cannot be changed (locked).
  • None – Lets the system know that there is no outdoor unit present.
    Note: Outside Unit Selection is only applicable for furnace installations.

Var-Speed RPM Clamp
 Allows reduction of the maximum compressor speed. Can be used to reduce outdoor unit operating noise or indoor blower airflow. This will also reduce the operating capacity.

Cool/Heat Airflow Adjust
 Controls airflow adjustment in cooling and heat pump heating, None (default), High (+10%), Low (-10%).

Utility Input Enabled?
If the system is using a “load shedding” device provided by the utility company set to ‘Yes’. The device must be connected to terminal U2 & U on the VSODU. Once the dry contacts are connected (non-powered) between U2 and U, change the setting to ‘Yes’. When set to ‘Yes’ the system will not start the condenser when the connection from U2 to U is open.

Heat Source
Allows selection of using just the furnace, or heat pump, as the sole heat source in a dual-fuel installation. If “Both” is selected, the system will stage up and down normally using the heat pump for initial heat stages, and then the furnace as auxiliary heat.

Furnace Locked Out Above
Select the outside temperature above which the furnace or supplemental electric heat will not run when matched with a heat pump. The default is disabled and the temperature can be adjusted between 0-55°F.

ECONET-RETST700SYS-Smart-Thermostat-52

Heat Pump Locked Out Below
 Selects the outside temperature below which the Heat Pump will not operate and your system will rely exclusively on the furnace or auxiliary heat source. This should be determined by evaluating the regions Heat Pump Balance point.

Aux Heat Defrost
This setting allows you to determine if you want auxiliary heat to run if there is a call for heat while the heat pump is in defrost mode.
Note: A difference of two degrees will be enforced between the furnace and heat pump. Lockout temperatures will be based off the outdoor temperature sensor connected to the outdoor unit and NOT off the temperature provided under weather.

Reversing Valve
This setting is only available when a non-communicating outdoor unit is installed with a gas furnace. ‘B’ type shall be used for Rheem heat pumps. All other brands change to ‘O’ type.ECONET-RETST700SYS-Smart-Thermostat-53

Thermostat Settings

Go to Menu > Settings > Installer (tap and hold) > Thermostat.ECONET-RETST700SYS-Smart-Thermostat-54

  • Thermostat Brand – The EcoNet Smart Thermostat will automatically populate when the system starts up by reading the equipment’s model data card.
  • Aux. Heat Hold Off Time – This setting is designed to keep the auxiliary heat off for a duration of time determined by the user. The time periods are:
    • Auto: The thermostat will energize Aux Heat once the temperature has reached 1 full degree beyond the heat set point. Also if the heating system is not maintaining the set point using the heat pump alone.
    • 1-60 min: The number of minutes the system will keep the Aux Heat from coming on even when the space temperature goes beyond 1 degree.
  • Filter Check Hour – The time of day when the EcoNet Smart Thermostat will check the air filter status.
  • Anticipator – Gives the user the ability to accurately control the system from overshooting in heating mode and the lag of delivering conditioned air in cooling mode. When set to 0 the system will use the factory default and recommended rate of equipment cycling to maintain comfort. Increasing the number will slow down the system, causing longer cycles. Reducing the number will make the system react quicker, shortening the equipment cycle.
  • Temperature Limits – You can configure the thermostat so only a specific heat and/or cool set point range is permitted.ECONET-RETST700SYS-Smart-Thermostat-55
  • Heat Set Point Maximum – You will not be able to set the thermostat to a temperature above this limit.
  • Cool Set Point Minimum – You will not be able to set the thermostat to a temperature below this limit.

Air Handler SettingsECONET-RETST700SYS-Smart-Thermostat-56

Air Handler Status (Menu > Settings > Installer > Air Handler)
Go to Menu > Settings > Installer (tap and hold) > Air Handler.
