Step 3
Next, see the Humidity Screen Display, which will
indicate the current local humidity. Use the Up/Down
arrow buttons to set the humidity set point for the
dehumidifier. If the humidity rises above the set point,
then the dehumidifier will switch ON and run continuously
until the humidity set point is achieved. There may be a
1-2 minute delay when the unit starts a dehumidifier ON
cycle before it actually begins dehumidifying, as there
is a compressor warm-up cycle required and indicated
by a red Compressor light. Likewise, if powering OFF,
there may be a short one minute delay required for the
unit to cycle down and shut off.
Step 4
From there, the unit will run and only needs to be switched
OFF for cleaning and maintenance if necessary.
Whole-House Configuration
After the dehumidifier is properly installed, ducted,
humidistat control wired, connected to AC power,
and condensate drain plumbed, standard operation
can be configured and initiated.
Step 1
Be sure to turn OFF the Dehumidifier Mode on the
external humidistat controller before switching on
the dehumidifier. Also, if an external float switch
is being used for the condensate drain circuitry, be
sure the condensate tank is empty or near empty
and the associated float switch is open.
Step 2
Push the power switch to turn the dehumidifier ON.
Step 3
Press the Central Control button until the Whole-
House light turns on, which indicates the unit is
configured for Whole House Mode of operation.
After a very brief delay, the dehumidifier will switch
into the Whole-House Mode.
Step 4
After setting the unit for Whole-House Mode in Step 3
above and from this point forward, the dehumidifier is
exclusively controlled by the dehumidistat. At this time,
the humidistat controller can be turned on and the humidity
setting adjusted accordingly. When the humidistat
signals the need for dehumidification, there may be a
1-2 minute delay when the unit starts a dehumidifier ON
cycle before it really begins dehumidifying, as there is a
compressor warm-up cycle required and indicated by a
red Compressor light. Likewise, if powering OFF, there
may be a short one minute delay required for the unit to
cycle down and shut off.
From here on, the unit will run and only needs to be
switched off for cleaning and maintenance if necessary.
