When the temperature measured is less than or equal to the Set - Diff. The unloading function is deactivated
or however, to prevent prolonged working in unloading with temperature conditions between activation set
and deactivation differential, when the condensation temperature is below the set, the time set is counted.
When this has expired the function is deactivated even if the temperature has not dropped below the set-
differential.
45.2 UNLOADING FROM CONDENSATION HIGH TEMPERATURE TRANSDUCER
The high pressure unloading function is active in cooling and heating units.
The function is managed by means of the analogue input configured as circuit condensation high pressure
probe.
FUNCTION ACTIVATED:
If the pressure measured by the condensation probe is equal to or exceeds the set for a time that can be set,
the unloading function of the circuit to which the probe belongs is activated. The power available is managed
via the parameter chosen of the steps to be inserted into the circuit.
FUNCTION DEACTIVATED:
When the pressure measured is less than or equal to the Set - Diff. The unloading function is deactivated or
however, to prevent prolonged working in unloading with pressure conditions between activation set and
deactivation differential, when the condensation pressure is below the set, the time set is counted. When this
has expired the function is deactivated even if the pressure has not dropped below the set-differential.
