Thermostat mode
Here it is dened how the thermostat is to be operat-
ed. Either as an ordinary ON/OFF thermostat or as a
modulating thermostat.When operation is ”modulat-
ing” the valve will limit the ow of refrigerant so that
the temperature variation will be less than for the
ON/OFF thermostat.The thermostat dierential (r01)
must not be set lower than 2K for ”modulating”. In a
decentralised plant you must select the ON/OFF ther-
mostat setting.
1=ON/OFF, 2=Modulating, 3=ON/OFF Common

Thermostat sensor
