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.
