S ETTING THE W ATER M ANAGEMENT S YSTEMS P ARAMETERS AND VALUES
There are 4 setup modes available in the water management as set out in the table below. The use of
these modes is based on 2 selection criteria:
Parameter 1 – DUMP VALVE DELAY
This provides the option for a 1 hour delay before dumping the
water from the tank. This function is particularly useful when
the unit is being used in THERM mode as it will stop premature
dumping of the water.
Parameter 2 – PRECOOL: The option to have the pump run for 2 minutes before the fan
starts. The benefit is that when the fan starts cool air will be
delivered immediately.
Parameter 3 – DUMP INTERVALS: This option provides the available hourly dump cycle times
available. These should be set according to water hardness in
the supply.
Parameter 4– PREFILL: The option provides the availability to have the valve prefill the
tank for 2 minutes before starting the pump operation.
