Aprilaire 8600 Touch screen Thermostat

INSTALLATION

INSTALLATION LOCATION RECOMMENDATIONS

The thermostat should be mounted:

• On an interior wall, in a frequently occupied space.
• Approximately 5‘ above floor.
• At least 18” from outside wall.
• Thermostat can be mounted to a vertical junction box.

Do not mount thermostat:

• Behind doors, in corners or other dead air spaces.
• In direct sunlight, near lighting fixtures, or other appliances that give off heat.
• On an outside or unconditioned area wall.
• In the flow of a supply register, in stairwells, or near outside doors.
• On a wall with concealed pipes or ductwork.

OUTDOOR TEMPERATURE SENSOR (OPTIONAL)

Outdoor temperature can be measured by attaching an 8052 sensor to the S1 and S2 terminals. The outdoor sensor must be enabled in the installer setup menu.

Heat pump models can use the outdoor temperature to effectively utilize the heat pump:

• When the outdoor temperature is less than the Low Balance Point, the heat pump will be locked out and only auxiliary heating will be used.
• When the outdoor temperature is higher than the High Balance Point, the auxiliary heating will be locked out and only the heat pump will be used to provide heating.

Outdoor temperature sensor should be mounted:

• On side of building out of direct sunlight (north side recommended).
• Above snow line.
• At least 3’ away from exhaust vents and condensing lines.
• Using less than 300’ of wire.
• Do not route wires along 120 VAC lines.

REMOTE TEMPERATURE SENSOR (OPTIONAL)

A remote temperature sensor can be used if the thermostat has to be mounted in a concealed location. A 8051 flush mount or 8053 surface mount remote temperature sensor can be attached to the T1 and T2 terminals and mounted in a recommended area. The remote sensor must be enabled in the installer setup menu. When the remote sensor is installed it overrides the internal sensor.

Remote temperature sensor should be mounted:

• On an interior wall, in a frequently occupied space.
• Approximately 5‘ above floor.
• At least 18” from outside wall.
• Using less than 300’ of wire.

Do not mount remote sensor:

• Behind doors, in corners or other dead air spaces.
• In direct sunlight, near lighting fixtures, or other appliances that give off heat.
• On an outside or unconditioned area wall.
• In the flow of a supply register, in stairwells, or near outside doors.
• On a wall with concealed pipes or ductwork.
• Near 120 VAC lines.

THERMOSTAT MOUNTING

1. Remove the rear mounting plate from the thermostat.
2. Pull wires through the opening on the back of the thermostat.
3. Position and level the mounting plate of the thermostat on wall and mark the hole locations with a pencil.
4. Drill 1/4” holes and insert supplied anchors (drywall only).
5. Place mounting plate over anchors, insert and tighten screws.
6. Seal wire entry holes to prevent drafts affecting temperature readings.

POWER & RESET OPTIONS

The thermostat is dual power. It can either be AC or battery powered, or both (to provide backup power for the clock). Batteries are optional if your thermostat was wired to run on AC power when installed.
For heat pump systems the C terminal must be connected to the common of the 24VAC transformer in order for the system fault and emergency heat indicators to operate. The thermostat has a memory backup that saves the thermostat settings in case of a power interruption. The system settings will be retained but the clock will reset after 90 seconds with no battery or AC power. The reset button located under the battery cover can be used to reset the thermostat to factory defaults. The system settings will also be reset to default.

WIRING TERMINAL

Wire specifications:
18-24 gauge thermostat wire

Installation notes:

• Ensure power at the HVAC equipment is off.
• Loosen screw terminals, insert stripped wire and re-tighten.
• Push the excess wire back into the opening and plug the wall opening to prevent drafts.

C – Common (optional when powered by batteries)
B – Reversing valve1
O – Reversing valve1
Y – 1st stage cooling/compressor
Y2 – 2nd stage cooling/compressor
G – Fan
RC – 24VAC supply cooling2
R – 24VAC supply heating2
W2 – 2nd stage heat / auxiliary
W – 1st stage heat / auxiliary
L – System fault indicator (optional) (heat pump only) S1 & S2 – outdoor temperature sensor (optional)
T1 & T2 – remote temperature sensor (optional) O and B terminals are both de-energized when system mode is OFF or in AUTO when the heating and cooling equipment is idle. 2 Jumper between RC & R is used in single transformer systems (see wiring diagrams).

MAIN MENU

TROUBLESHOOTING

DISPLAY IS BLANK

• Check circuit breaker and reset if necessary.
• Make sure power switch at heating & cooling system is on.
• Make sure furnace door is closed securely.
• If thermostat is battery powered, make sure fresh AA alkaline batteries are correctly installed.

TEMPERATURE SETTINGS DO NOT CHANGE

Make sure heating and cooling temperatures are set to acceptable ranges:

• Heat: 40° to 90°F (4° to 32°C).
• Cool: 50° to 99°F (10° to 37°C).

HEATING SYSTEM DOES NOT RESPOND
(“HEATING” APPEARS ON SCREEN)

• Check for 24VAC at the equipment on the secondary side of the transformer between power and common. If voltage is not present, check the heating equipment to find the cause of the problem.
• Check for 24VAC between the heat terminal (W) and the transformer common. If 24VAC is present, the thermostat is functional. Check the heating equipment to find the cause of the problem.
• Check for loose or broken wires between the thermostat and the heating equipment. COOLING SYSTEM DOES NOT RESPOND

(“COOLING” APPEARS ON SCREEN)

• Check for 24VAC at the equipment on the secondary side of the transformer between power and common. If voltage is not present, check the cooling equipment to find the cause of the problem
• Check for 24VAC between the cooling terminal (Y) and the transformer common. If 24VAC is present, the thermostat is functional. Check the cooling system to find the cause of the problem.
• Check for loose or broken wires between the thermostat and the cooling equipment.

FAN DOES NOT TURN ON IN A CALL FOR HEAT

• Check System Setting 05 (Fan Control), to make sure the fan control is properly set to match the type of system (see page 6).

HEAT PUMP ISSUES COOL AIR IN HEAT MODE, OR WARM AIR IN COOL MODE

• Check wiring at the terminal block to confirm the reversing valve is connected to the proper terminal. O is active in cooling and B is active in heating.

HEAT/COOL BOTH ON AT SAME TIME

• Check SW1 (Equipment Type), to make sure it is set to match the installed heating/cooling equipment (see page 5).
• Check to make sure heating and cooling wires are not shorted together.

HEATING EQUIPMENT IS RUNNING IN COOL MODE

• Check SW1 (Equipment Type), to make sure it is set to match the installed heating/cooling equipment (see page 5).

“HEATING” IS NOT DISPLAYED

• Check Installer System Setting number 01

(Control Setup) is set correctly.

• Change the System Mode to Heat, and set the temperature level above the current room temperature.

“COOLING” IS NOT DISPLAYED

• Check Installer System Setting number 01

(Control Setup) is set correctly.

• Change the System Mode to Cool, and set the temperature level below the current room temperature.

ERROR CODES

If the thermostat enters an error mode, all outputs are turned off. The thermostat attempts to recover every 10 minutes. If the error does not clear, use the reset button. This will return all settings back to factory default.

Error code	Message	Error Description
01	“SENSOR ERROR”	Open temperature sensor circuit
02		Shorted temperature sensor circuit
04	“EEPROM ERROR”	Error in permanent memory
