Min Cycle off time: Configures the minimum compressor
off time between cycles (240 to 900 seconds).
Min outdoor temp: Disables the compressor when the
outside air temperature reaches the configured minimum
setting. This performs two functions. It prevents the
compressor from running when the outdoor temperature
is too low, thus resulting in damage to the compressor.
You can also set this value to determine when you 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 Simultaneous Operation: If you select Enable and there is a source of auxiliary heat, it will turn on in addition to the heat pump. The heat pump will be engaged for the first 30 minutes. If, after 30 minutes, the set point has not been met, the auxiliary heat will also be engaged to assist the heat pump in reaching the set point.
If you select Disable, the heat pump will be engaged for up to 2 hours. If after 2 hours the set point has not been met, the thermostat will shutdown the heat pump and engage the auxiliary heat to reach the set point. This option should also be used for installation where the heat pump evaporator coil is downstream from the source of auxiliary heat. This setting is only available when the Comp to Aux Temp Delta and Comp to Aux Runtime settings are both set to Auto (default).
