11.10. Thermostat function
Three thermostat functions can be activated in the controller. The description below relates to the first thermostat
function.
A thermostat function is activated by allocating the thermostat output THA1 and thermostat sensor THF1.
The thermostat output is switched on if the temperature drops below the reference value less half the differential
gap, and is switched off if the sensor temperature rises above the reference value plus half the differential gap.
The function starts switched-off when the controller is restarted.
