1. Press the ON/OFF button to turn the dehumidifier control ON
Dehumidification of the Primary Zone follows the same sequence as described to
the left for Single Zone, with or without a Model 76 external control
installed in the Primary Zone The dehumidifier control display will show
PRIMARY ZONE in addition to that described to the left when sampling or
dehumidifying the Primary Zone The zone dampers are energized when sampling or
dehumidifying the Primary Zone
2. The Secondary Zone uses the humidity setting on the dehumidifier control
During Secondary Zone sampling or dehumidification, the zone dampers are de-
energized and the HVAC blower (if on) stops SECONDARY ZONE will show on the
dehumidifier control display when the Secondary Zone is either sampling or
dehumidifying If the Primary Zone had just finished a dehumidification demand,
the compressor will continue to run during Secondary Zone sampling to prevent
short cycling of the compressor
The Secondary Zone is sampled immediately after the Primary Zone has finished
sampling, or if there is a call for dehumidification from the Primary Zone,
immediately after the call has been satisfied When a Model 76 external control
is installed, the Secondary Zone will be sampled once per hour if there has
not been a call for dehumidification from the Primary Zone Secondary Zone
sampling will also occur whenever the setting on the dehumidifier control is
lowered

SEQUENCE OF OPERATION When wired as shown in FIGURE 28, the ventilation damper
will open whenever there is an HVAC heating (W), cooling (Y) or fan (Gs) call,
allowing fresh air to be brought in when the HVAC blower is running (see
VENTILATION WITH AN EXTERNAL CONTROL section below for exceptions) The
ventilation damper will also open if the dehumidifier is operating VENTILATING
will show on the dehumidifier control when the dehumidifier is actively
ventilating When the HVAC call ends, the dehumidifier stops, or after the set
amount of ventilation time has been met, the ventilation damper will be closed
If the set amount of ventilation time has not been met before the end of the
one-hour cycle, the dehumidifier will turn on the ventilation damper along
with the HVAC blower to ensure the desired ventilation time is satisfied If
the dehumidifier has been set up to operate ventilation with outdoor
temperature restrictions (AUTO-B, AUTO-C or AUTO-D refer to page 20) then
ventilation will be limited as described DEHUMIDIFYING THE FRESH AIR When the
dehumidifier is set up for single zone and there is no external control
installed, the dehumidifier will turn on its blower and measure the RH of the
air entering the dehumidifier during ventilation when ducted as shown in
FIGURE 26 If the relative humidity of the air entering the dehumidifier is
higher than the setting, the dehumidifier compressor will turn to remove
moisture VENTILATION WITH AN EXTERNAL CONTROL When an external control is
installed the dehumidifier will open the ventilation damper only when there is
a cooling call (Y) or when the dehumidifier is operating, unless the
ventilation need has not been met If the set amount of ventilation time has
not been met before the end of the one-hour cycle, the dehumidifier will turn
on the ventilation damper along with the HVAC blower to ensure the desired
