HUMIDIFICATION/DEHUMIDIFICATION: PRESERVATION OF AMBIENT HUMIDITY
The humidity and the dehumidification call is managed in neutral area depending on the
set humidity setpoint (“Set RH%” label in “Home 1”) and to the humidity differentials
(parameters dUU and dUd in “Parameters > Process regulation”). Dehumidification is
activated upon exceeding of set + dUd and remains active until set is achieved (with
dnd=0). Humidification is activated below set - dUU and remains active until set is
achieved (with dnU=0).
It is possible to set a "dead area" with parameters dnd and dnU that deactivates
humidification and dehumidification when humidity is between SET-dnU and SET+dnd.
The humidity management can be excluded with parameter H
r in “Parameters > Configure
PAN
”. Dehumidification only can be excluded with parameter End.
Humidification only can be excluded with parameter EnU.
There are four dehumidification methods (parameter dE
U in “Parameters > Configure
PAN
”):
0. Dehumidifies with the cold
(the cold is called to dehumidify, the hot is added only to
maintain ambient temperature)
1. Dehumidifies with the hot
(the hot is called to dehumidify, the cold is added only to
maintain ambient temperature)
2. Separate dehumidification
(only the dehumidification output activates but hot and cold
are not called)
3. Dehumidification separate and working with cold off
(separate dehumidification that
is activated only if a cold call is not in progress)
It is possible to give a maximum time for the dehumidification phase (parameter dEt in
“Parameters > Machine protection”) by signalling an alarm.
