Aprilaire 8600 Touchscreen Thermostat

Aprilaire 8600 Touchscreen Thermostat  pro Installation

Thermostat should be mounted:

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

The thermostat should be mounted

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

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.

The outdoor temperature sensor should be mounted

  • On side of the 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 linesAprilaire-8600-Touchscreen-Thermostat-featured

Remote temperature sensor (optional)

A remote temperature sensor can be used if the thermostat has to be mounted in a concealed location. 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 setup menu. When the remote sensor is installed it overrides the internal sensor.

The remote temperature sensor should be mounted

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

Do not mount the 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.Aprilaire-8600-Touchscreen-Thermostat-fig-2

Thermostat mounting

Aprilaire-8600-Touchscreen-Thermostat-fig-2

  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 the wall and mark the hole locations with a pencil.
  4. Drill 1/4” holes and insert supplied anchors (drywall only).
  5. Place a mounting plate over anchors, insert, and tighten screws.
  6. Seal wire entry holes to prevent drafts from 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

Aprilaire-8600-Touchscreen-Thermostat-fig-4Wire specifications:
18-24 gauge thermostat wire

Installation notes

  • Ensure power at the HVAC equipment is off.
  • Loosen screw terminals, insert the 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 the system mode is OFF or in AUTO when the heating and cooling equipment is idle.
A jumper between RC & R is used in single transformer systems (see wiring diagrams).

The following table is the list of the settings and their details. Default settings are shown in bold. Some settings are only available to thermostats set to heat pump mode. In heat pump mode, this system setting is also the auxiliary heat setting. If utilizing a fossil fuel auxiliary heat system, set it to a Gas or Oil Furnace. In this setting, the heat pump will lock out before the fossil fuel auxiliary heat comes on; eliminating the need for a dual-fuel kit. If utilizing electric auxiliary heat, set it to Electric. In this setting, the heat pump and electric auxiliary heat are allowed to run simultaneously.

  • Cool: 50° to 99°F (10° to 37°C).

Heatin g system does not respond (“HEATING” appears on screen)

  • Check for 24VAC at the equipment on the secondary side of the transformer between the 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 is 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 heating equipment.

The cooling system does not respond (“COOLING” appears on the 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 is 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 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 the 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 the 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 the heating and cooling wires are not shorted together.

The 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).

The 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).
