Parameter C1 introduces a delay between a switch-off and the subsequent re-activation of
the cold. Hot can be deactivated with parameter EnH (EnH=0 disables the hot relay in all
conditions).
HUMIDITY/DEHUMIDIFICATION: AMBIENT HUMIDITY MAINTENANCE
The humidity and the dehumidification call is managed in neutral area depending on the
set humidity setpoint (
key 4) and by the humidity differentials (parameters dUU and
dUd). Dehumidification is activated upon exceeding of set + dUd and remains active until
set is reached (with dUn=0). Humidification is activated below set - dUU and remains
active until set is reached (with dUn=0).
It is possible to set a "dead area" with parameter dUn that deactivates humidification and
dehumidification when humidity is between SET-dUn and SET+dUn.
The humidity management can be excluded with parameter Hr.
Dehumidification only can be excluded with parameter End.
Humidification only can be excluded with parameter EnU.
There are three dehumidification modes (parameter dEU):
1. Dehumidifies with the cold (the cold is called to dehumidify, the hot is added only to
maintain ambient temperature).
