The two controls (Cooling and Heating) operate in such a way that the corresponding relays switch off at the
setpoint. If the measured value differs more than the differential (hysterisis) from the setpoint, the relay switches on.
This is assuming that for cooling and heating there is no offset.
If there is an offset, the effective setpoint (which is used for regulation) shifts with the offset value relative to the
setpoint.
The following values are default values set at the factory:
Adjustment Value
Cooling Differential 0.2°C
Cooling Offset -0.1°C
Heating Differential 0.2°C
Heating Offset -0.6°C
The resulting characteristics of the heating and cooling controls are:
Please note:
When changing differentials and offsets of cooling and heating, the PROBA 50 ensures that no situations arise with
which it is possible that cooling and heating are switched on at the same time. In case the user tries to change the
parameter in this way, the
PROBA 50 signals and the faulty adjustment is blocked.
