Three fan modes are available:
Sense mode: When the dehumidier is on standby, the fan will start every 15 minutes for 1
minute to circulate the room air over the internal sensor element.
Is used if installation has long air ducts.
Continuous mode: Fan runs continuously to circulate room air.
Intermittent mode: Fan runs only when heating, cooling or dehumidication is active.
If installation has long return air ducts, use external RH/T room sensor.
The equipment has to have means of disconnection from power supply according to the local
regulations.
The power cord must comply with local legislation, where the equipment is used.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or si-
milarly qualied persons in order to avoid a hazard. Only connect power via a properly earthed
power cable that is fused according to relevant regulation.
CAUTION
The unit is tted with ’Schrader’ type service valves on the LP side of the cooling circuit.Schrader valves
HP pressostat The dehumidiers are tted with a HP pressostat with manual reset. The HP pressostat can
be located by opening the inspection door from the front side of the dehumidier, where the
touch panel is located.
Note that it is not possible to relocate the HP pressostat if the inspection side is switched
around. A soft HP/LP function has also been implemented to protect the system. If the soft HP/
LP function is activated, the system will stop for a xed duration before attempting to return to
normal operation. If the soft HP function has been activated 6 times within an hour, the com-
pressor will be blocked from starting again until reset. The soft LP and HP function will auto-
matically be reset by the controller unless it is activated 6 times within an hour, which requires
manual reset.
The time between compressor start-ups is limited by a 10 minutes timer, where the compressor
must run for minimum 6 minutes, and must be o for minimum 4 minutes before it is started
again.
The restart timer will prevent instant start of compressor when power is switched on.
The timers protect the compressor against overloading caused by too frequent starting cycles.
