EL. REAHEAT ENABLE
During dehum operation it could be
necessary to reheat. If it is no problem for the
power consumption, put this parameter to
YES. If compressor and reheat may not
operate at the same time, put it to NO.
YES
dHh
DEHUM. HYSTERESIS
Defines the return air humidity value at which
the dehumidification will be stopped. It is
expressed as percentage of the full humidity
proportional band. (50% means that
dehumidification will be stopped at room
humidity setpoint.
50%
ddb
DEADBAND
The value the dehumidification shall start
later. Means the dehumidification is shifted
with the deadband value to higher humidity.
0%
dEC
DEHUM. RELAY AS
Allows using the digital output of
dehumidification for other purposes, if the
dehumidification mode is not required:
DEHUM:
Dehum relay used for dehumidification
(standard)
WARNING:
Relay used as general warning contact
NO POWER:
relay changes its status if the unit switches to
NO POWER Mode
DEHUM
LSt
WATER LEAK DETECTOR
Enables or disables the sensor. When
enabled can be set to warning (message
only) or to alarm (stops the unit).
NO
dt1
DT ROOM-OUTDOOR
The value of the difference between the
return air temperature and the outdoor
temperature over which the unit will enable
freecooling mode.
If it is set to CON the control expects to get a
command by a switch instead of a temp.
sensor.
If it is set to EFC the unit will not go in
freecooling mode during normal operation but
only in case of NO POWER operation or
compressor failure and the delta t is 3 deg. C.
NO
dt2
DT ROOM-GLYCOL
The value of the difference between the
return air temperature and the glycol
temperature over which the unit will enable
freecooling mode.
If it is set to CON the control expects to get a
command by a switch instead of a temp.
sensor.
NO
dt3
STOP FC AT SET+
The freecooling mode will be stopped if the
return air temperature will be greater than
room temperature setpoint plus STOP FC AT
SET+. If freecooling is stopped for this
reason it will be disabled for at least one
hour.
NO
