Temperature regulation I:
In this case the thermostat is to be applied in connection with
heating systems or refrigerating systems. The requested
temperature is regulated in the scale with temperatures from
-10°C to +50°C. Check that the hysteresis (Diff) is adjusted
to what is requested (hysteresis at 1°C is recommended for
control of room temperature).
Temperature regulation II:
In this case the thermostat is to be used as a difference
thermostat for regulation of snow and ice melting systems.
The range of the thermostat is decided by adjusting the
temperature range -10°C to +50°C (requested max.
temperature) and the temperature range -10°C to +5°C
(requested min. temperature). If the heating system has to
be connected when the temperatures are b5°C to -
5°C the min. temperature is set to -5°C and the max.
temperature to +5°C.
