Item Switch/Indicator Function
1 Run/Stop Switch With the run/stop switch selected to the position, the unit is switched off.
With the mode switch in the “MAN” position, operating the run/stop switch to the
position will start the dehumidifier.
With the mode switch in the “AUTO” position, operating the run/stop switch to the
position will allow an external humidistat or RH98 to control the operation of
the dehumidifier.
2 Mode Switch With the mode switch in “MAN” position, the dehumidifier will operate in the manual
mode. In this mode the unit will run continuously when the run/stop switch is
operated to the position.
With the switch in the “AUTO” position, the dehumidifier will operate in the automatic
mode. In this mode a humidistat or RH98 must be connected to the unit. When the
run/stop switch is operated to the position, the humidistat or RH98
determines when the dehumidifier will start and stop.
3 Power Connected Indicator Indicates that mains power is connected to the dehumidifier.
4 Unit Running Indicator Indicates that the dehumidifier is running, or is ready to start on a signal from the
humidistat or RH98 (automatic mode).
5 Fault Warning Indicator Indicates that the unit has shut-down due to the control circuit detecting that either
the high temperature cut-out or the fan motor overload has tripped.
For units fitted with an air cooled condenser, the fault warning indicator is activated
when there is a condenser fan or heater fault.
