Installation Instructions

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 residential 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.
• 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 the new thermostat connector marked
G or F	Fan	G
Y1, Y or C	Cooling	Y1
W1, W or H	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

Note: O/B is used if your system is a Heat Pump.

The T5800 Thermostat Backplate

NOTE: The backplate does not fully cover a full size vertical junction box. The ACC-WPLWH ColorTouch Wallplate or a single-gang, horizontally mounted junction box would be needed for that type of installation.

To remove the thermostat backplate:
Using the Finger Pull Areas, pull the front housing away from the backplate.

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.
• 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.
• 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.

Heat Pump Systems with Dual Fuel

Free Cooling utilizes the Y1 terminal for the operation of 1st stage cooling. If mechanical (compressor) cooling is also present, the mechanical cooling is connected to the Y2 terminal in this instance.
Free Cooling may be used with a Gas/Electric or Heat Pump system. Temperature Sensor: ACC-TSEN Temperature Sensor 10K ohm sensor at 77F/25C. Negative Temperature Coefficient.

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.
• 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 28).
• 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 28).
• 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 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.
