AUXILIARY OUTPUT
The thermostat provides an auxiliary heating output that
can act as a second stage of heating when controlling
ambient temperature.
If the room temperature is too far from the setpoint or the
main stage of heating has difficulties raising the
temperature, the auxiliary output activates the secondary
heating source to reach the set temperature.
Both outputs can control different types of heating load and
can be configured in the user settings.
