COLD/HOT: PRESERVATION OF AMBIENT TEMPERATURE
The cold and hot call is managed in neutral area depending on the set temperature
setpoint
(“Set Temp” label in “Home 1”) and to the temperature differentials (parameters
dtC and dt
F in “Parameters > Process regulation”). The cold is activated upon exceeding
of set + dtF and remains active until set is achieved (with dnF=0). The hot is activated
below set - dtC and remains active until set is achieved (with dnC=0). It is possible to set a
"dead area" with parameters dtn that deactivates hot and cold when the temperature is
between SET-dnC and SET+dnF.
Parameter C1 (in “Parameters > Machine protection introduces a delay between a switch-
off and the subsequent re-activation of the cold. Hot can be deactivated with parameter
EnH in “Parameters > Configure PAN” (EnH=0 disables the hot relay in all conditions).
Cold can be deactivated with parameter EnC in “Parameters > Configure PAN” (EnC=0
disables the cold relay in all conditions).
