INSTALLATION There are 5 steps to install the thermostat: Step 1 — Power Off HVAC Equipment Step 2 — Remove Existing Thermostat Step 3 — Install the Wi-- Fi Thermostat Step 4 — Connect the Wiring Step 5 — Power On HVAC Equipment Step 1. Power Off HVAC Equipment Before disconnecting the existing thermostat, or installing the Legacy Line Wi--Fi Thermostat, disconnect the power to the heating and air conditioning equipment. Step 2.
To install the thermostat: 3. Gently separate the backplate from the thermostat. 4. Place the thermostat backplate on the wall. Make sure that any existing wires can be inserted through the opening on the backplate. 5. Using the backplate as a template, mark the location of the mounting holes on the wall as shown below.

Select Settings " Installation Settings. Select Equipment. Configure the devices connected to the thermostat.
d meet the set temperature. The temperature range is adjustable from 0 to 65° F (–17.8 to 18.3° C) or can be completely disabled. Note: You need an Internet connection for this feature to operate properly. Allow HP with Aux Heat If you select Yes and there is a source of auxiliary heat, it will turn on in addition to the heat pump. The heat pump will be energized for the first 30 minutes.
Thresholds This section configures the temperature and time thresholds associated with the heating and cooling equipment. You must configure the Equipment settings (page 22) before setting the thresholds. Only the applicable threshold settings will be displayed (i.e. if no air conditioner is configured, you will not see the options related to air conditioners).

want the auxiliary heat (if installed) to engage to help meet the set temperature. The temperature range is adjustable from 0 to 65° F (–17.8 to 18.3° C) or can be completely disabled. Note: You need an Internet connection for this feature to operate properly. Aux Heat Settings d Max Outdoor Temperature Configures the maximum outdoor temperature threshold. Above this level, the auxiliary heat will not be activated. The temperature is adjustable from 0 to 80° F (26.5° C) in increments of 0.5° F (0.3° C).
Advanced Settings These options customize how long each stage will run before the next stage turns on. You may also program when a particular stage is turned on based on the temperature delta between the set temperature and the current temperature. d Reverse Staging If enabled, the thermostat will cycle down from the higher stages so that when it approaches set point it will only be running in stage 1.
Temp Correction Lets you program an offset between the real temperature at thermostat and the displayed temperature. If you find that the temperature where the thermostat is located does not represent the room temperature, change the offset to compensate for the difference. The correct temperature is adjustable from +/-- 10° F in 0.5° F (0.3° C) increments. Installer Code To prevent accidental modifications to the installation settings, you can enable a 4--digit installer code.
Reset HVAC Equipment Settings You can quickly restore all HVAC equipment settings on the thermostat back to their factory defaults. Any user setting (not related to the equipment installed) will remain unchanged.
