Wall Iocations
The thermostat should be installed approximate 4 to 5 feet above the floor.
Select an area with average temperature and good air circulation.
Do
not Install thermostat at following places:
- Close to hot or cold air ducts
- With direct sunlight
- With an outside wall behind the thermostat
- The areas that do not require conditioning
- Where there are dead spots or drafts (in corners or behind doors)
- Where there might be concealed chimneys or pipes
Installation Tip

temperature of the location should be representative of the building.
SUBBASE INSTALLATION
Caution: Electrical Hazard Failure to disconnect the power before
beginning to install this product can cause electrical shock or equipment
damage.
Failure to disconnect the power before beginning to install this product can
cause electrical shock or equipment damage.
Caution: Equipment damage hazard
Do not operate the cooling system if the outdoor temperature is below 50° F
(10° C) to prevent possible compressor damage.
Insert the awl into the slot and pry up the front part of the panel to open
it.
For horizontal mount put one screw left and one screw right.
WIRING
Caution: Electrical Hazard
Failure to disconnect the power before beginning to install this product can
cause electrical shock or equipment damage.
Warning:
All components of the control system and the thermostat installation must
conform to Class Il circuits per the NEC Code.
Wiring
- If you are replacing a thermostat. Take notice of the terminal connections on the cases, the wiring connections may not be color coded. For example, the green wire may not be connected to the G terminal.
- Loosen the terminal block screws. Insert wires then retighten terminal block screws.
