Desert Aire - CM3500 Manual
Aura Q-Pump Inverter Plus models will not include the staged heating timers,
but will include a Suction Valve Off time delay. This delay will force the suction
valve open or closed for this amount of time after the limit switches make to
insure the correct operation of the valve.
The water flow alarm time enables a delay after starting the water pump. The
water flow switch will need to be on before this delay times out or a Low Water
Flow alarm will disable the unit. The Compressor On delay will allow the water
pump to run for one (1) minute before the compressor will turn on. The Pump /
Valve Off delay will run the pump for two (2) minutes after the compressor is
cycled off.
The Fan Delay and Air Flow Delay work together to allow the supply fan to
ramp up to full speed over an extended period of time. The fan delay time will
start once the fan starts and will not set the low air flow alarm during this initial
start. After this time, a low air flow condition will need to be present for the Air
Flow Delay time to set the alarm.
The Damper On/Fan Delay will delay the start of the fan until the damper
has been energized for the delay time. After this time, the fan will start if the
damper end switch is closed.
Aura Q-Pump Inverter Plus models will also include oil management timers.
The oil level indicator is shown here to aid in troubleshooting. The low level
delay will insure that the oil level has dropped before the compressor is
commanded to maximum speed. The off delay will keep the compressor at
maximum speed after the oil level is back to normal. If the oil level does not
return to normal for the alarm delay time, the dehumidifier will stop and
indicate a low oil level alarm.
To modify the time delays, press the ENTER key and use the arrow keys until
the desired setting is shown. Press the ENTER key to accept the delay value.
