Emergency
cooling
Emergency cooling will occur when
there is either compressor fault or loss
of AC power.
Since active cooling is not possible, the
damper will attempt to provide fresh air
cooling to keep the return temperature 3
degrees below set point even when it is
not possible because of high ambient
temperatures.
At compressor fault:
The compressor fault timer must have
returned to zero before the emergency
cooling situation will end.
At loss of AC mains:
Mains AC power must be back before
the emergency cooling situation will end.
Service/occupied
mode
The service mode should be activated to
make a comfortable climate in the
shelter during service.
In service mode the unit will switch
between active cooling, free cooling,
heating and recycling to maintain:
•
comfort temperature between
20-25 °C
•
low fan speed to reduce sound level
and air flow
Service mode is only for use when
technicians are working in the shelter.
After one hour in service mode the unit
automatically switches back to normal
operation.
It is possible to reactivate the button for
another period of one hour.
