Aprilaire S86WMUPR Wi-Fi Programmable Thermostat Installation Instruction

Aprilaire S86WMUPR Wi-Fi Programmable Thermostat

INSTALLATION

INSTALLATION LOCATION RECOMMENDATIONS

The thermostat should be mounted:

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

Do not mount the 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 (INCLUDED)

Outdoor temperature can be measured by attaching the included 8052 sensor to the T1 and T2 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 lower than the Low Balance Point, the heat pump will be locked out and only auxiliary heating will be used to provide heating.
• 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.

Indoor Air Quality functions can use the outdoor temperature sensor to:

• Control humidification set point based on outdoor temperature to prevent condensation.
• Lock out ventilation based on high and/or low outdoor temperatures.
• Display outdoor temperature on thermostat.

Outdoor temperature sensor should be mounted:

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

REMOTE TEMPERATURE SENSOR (OPTIONAL)

A remote temperature sensor can be used for control if the thermostat is to be mounted in a concealed location or a remote sensor can be averaged with the thermostat sensor to control a large space. An 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 set-up menu, and once enabled will override or be averaged with the thermostat’s internal temperature sensor, based on the setting.

Remote temperature sensor should be mounted:

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

WIRELESS SENSORS

This thermostat is compatible with the following AprilAire wireless sensors:

• Model Z10IDT Indoor Temperature and Humidity Sensor Up to eight of these sensors can be connected to the thermostat. Connected sensors will automatically be averaged, or individual sensors can be selected for scheduled events.
• Model Z10ODT Outdoor Temperature and Humidity Sensor One sensor can be connected to the thermostat.

The wireless sensor settings can be found under the thermostats’ installer settings. See the sensors instruction manual for mounting and connecting details.

THERMOSTAT MOUNTING

1. Remove the rear mounting plate from the thermostat.
2. Pull wires through the opening on the back of the rear mounting plate.
3. Position and level the mounting plate of the thermostat on wall and mark the hole locations with a pencil.
4. Insert and tighten supplied selfdrilling 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 AND RESET OPTIONS

• The thermostat is powered by 24VAC. In the case of power loss, the thermostat will maintain the clock for 2 hours. The thermostat has a memory backup that saves the thermostat settings in case of power interruption. The thermostat can be set back to factory defaults from the installer settings menu. See Installer System Settings section for details.
• The factory reset does not clear thermostat account information from the AprilAire Wi-Fi
• Thermostat App. To clear this information, remove the thermostat from the app or use the unregister option from the thermostat’s Wi-Fi settings.

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.

TROUBLESHOOTING

DISPLAY IS BLANK

• Check circuit breaker and reset if necessary.
• Make sure power switch at heating & cooling system is on.
• Make sure the furnace door is closed securely.

THE 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

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).

THE 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

THE FAN DOES NOT TURN ON IN A CALL FOR HEAT

Check System Setting (Fan Control in Heating), to make sure the fan control is properly set to match the type of system (see page 19).

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

Check System Setting (O/B Operation) to make sure the reversing valve operation matches the heat pump.

HEAT/COOL BOTH ON AT SAME TIME

• Check System Setting (Equipment Type), to make sure it is set to match the installed heating/cooling equipment (see page 19).
• Check to make sure heating and cooling wires are not shorted together.

HEATING EQUIPMENT IS RUNNING IN COOL MODE

• Check System Setting (Equipment Type), to make sure it is set to match the installed heating/cooling equipment (see page 19).

“HEATING” IS NOT DISPLAYED

• Check System Setting (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 System Setting (Control Setup) is set correctly.
• Change the System Mode to Cool, and set the temperature level below the current room temperature.

HUMIDIFIER DOES NOT OPERATE IN AUTO MODE

• Check Installer System Setting number (Outdoor Sensor) is set to Yes.
• Verify that the outdoor sensor is functioning correctly. If the sensor is functioning correctly the outdoor temperature will display in the outdoor temperature location (see SCREEN SAVER on page 42 for the location).
