The Navigation buttons are used to change various parameters on
the thermostat, including the temperature setpoints. These
buttons are located beneath the display.
The Mode/Select button is used to navigate through the various
thermostat screens, including the weather screens. This button is

Installing a Remote Sensor
Follow these steps to install the remote sensor:
1.Drill a 1/4" hole into the drywall where you want to install the sensor.
2.Fish the cable that connects to the sensor through the 1/4" hole in the wall until the edge of the sensor, where the cord meets the sensor, is flush against the wall.
3.Apply caulk, drywall putty, insulation, or any other appropriate sealant to the hole in the wall around the sensor to seal the hole.
4.Attach the connecting wires from the sensor to the S1 and S2 terminals on the thermostat.
Note: You can use a maximum of 300 ft (91.44 m) of 18 AWG wire for connecting the indoor/outdoor remote sensor to the thermostat.
The thermostat automatically defaults to using the
Mounting the Base to a Wall
You should only mount the thermostat onto a sheetrock wall with the anchors and screws provided with the unit. There are four screw holes located on the base of the thermostat. No tools are required to disassemble the thermostat— simply use your hands to pull the front panel off of the base.
1.Place the base over the wire hole opening in the wall. Level the base (leveling required for appearance only) and mark the screw hole mounting locations.
2.Using the supplied wall anchors, drill 1/4" hole in the center of the marked locations, and tap the wall anchors into the holes. If using the supplied screws only, drill a 3/32" hole in the center of the marked locations.
Note: Minimize the wire entry hole size and seal. Drafts from inside the wall could affect temperature readings.
3.Fasten the base to the wall with the supplied screws.
4.Seal the wire entry with caulk, drywall putty, or insulation.
Wiring the Thermostat
Note: A qualified HVAC technician should perform these steps to ensure proper termination.
1.Make sure the HVAC system power is off.
2.Strip 1/4" (0.63 cm) of insulation from each wire you are using.
3.Secure the wires into the terminals on the base according to the appropriate wiring diagram. Use
4.Check each wire to ensure it is securely fastened, not broken, and any exposed wires are not touching each other.
