Minimum on time

The minimum on time applies to any heat or cool mode. After load of the heating or cooling system

temperature or control mode resets the minimum on time counter. You can set the minimum
on time from 0 minutes to 5 minutes in the installer configuration settings menu. The default
minimum on time is 4 minutes.

When enabled, the emergency heat engages only if the ambient temperature is lower than the set
temperature. When the thermostat is in heat or cool mode, press Mode for 5 seconds to enable
emergency heat. Follow the same step to disable emergency heat.
