The heating and compressor outputs are activated together when humidity is higher than SET %RH+dbH value. Outputs are disabled when humidity
comes back to the SET %RH value.
4.2.1 Relation between cooling, heating and dehumidifying
1.
If is simultaneously present a request of cooling (temp>SET TEMP+dbt) and dehumidifying (RH > SET %RH+dbH): the cooling action has the
priority over the dehumidifying action: only the compressor relay is energised till the SET TEMP is reached at this point also the heating relay
is enabled.
2.
If is simultaneously present a request of heating (temp< SET TEMP-dbt) and dehumidifying (RH > SET %RH+dbH): the dehumidifying action
has the priority over the heating action: both the compressor and the heating relays are energised till the humidity set is reached at this point
only the heating relay is enabled.
4.3
DEHUMIDIFYING ACTION WITH DEHUMIDIFIER RELAY (OA1 = DEH)
The configurable relay is used,
setting the parameter
oA1 =dEH.
NOTE:
the LIGHT button is not more available;
Two kinds of de-humidifying are available:
4.3.1 Dehumidifying action with ONLY de-humidifier relay
By setting the parameter
tHu
=
db
the de-humidifying action is performed by enabling the de-humidifier relay when the humidity is higher than SET
%RH
+ dbH.
The relay is switch off when humidity comes back to the SET %RH value.
4.3.2 Dehumidifying action with de-humidifier and compressor relays
By setting the parameter
tHu
=
cHu
the de-humidifying action is performed by enabling the de-humidifier and compressor relays together. when the
humidity is higher than SET %RH
+ dbH.
The relays are switched off when humidity comes back to the SET %RH value.
If is simultaneously present a request of cooling (temp>SET TEMP+dbt) and dehumidifying (RH > SET %RH+dbH): the cooling action has the priority
over the dehumidifying action: only the compressor relay is energised till the SET TEMP is reached at this point also the de-humidifier is enabled.

The fan control mode is selected by means of the “
FnC
” parameter:
FnC=C-n
fans will switch ON and OFF with the compressor and
not run
during defrost
:
;
FnC= O-n
fans will run continuously, but not during defrost
FnC=C-y
fans will switch ON and OFF with the compressor and
run
during defrost;
FnC=O-y
fans will run continuously also during defrost
