For cooling operation, turn unit on via POWER button.
1.
Select Cooling mode via MODE button.
2.
Room temperature and set point temperature are
displayed.
3.
Setpoint temperature changes by one degree with
each successive press of UP or DOWN ARROW buttons.
Holding button in changes temperature rapidly.
4.
Place setpoint temperature below room temperature.
5.
Three (3) minutes after turning on power, cooling
starts and continues for minimum of two (2) minutes
and continues cooling as long as setpoint remains
below room temperature.
6.
Cooling LED illuminates as long as unit is calling for
cooling.
7.
Once room temperature is satisfied for at least sixty
(60) seconds and two (2) minute minimum run time
has elapsed, cooling cycles off.
8.
Fan operates as described in Fan Operation.
See Page 30.
9.
Once cooling has cycled off or following power outage,
cooling does not restart for at least three (3) minutes

Optional Heating Mode
Optional Electric Or Hot Water Heat Operation
For operation with optional electric or hot water heat
control must be configured properly (Heat Source – ON,
Heat Pump – OFF. See Figure 37, Page 26.
For electric or hot water heat operation, turn unit on via
POWER button.
1.
Select Heating mode via MODE button.
2.
Room temperature and setpoint temperature are
displayed.
3.
Press either UP or DOWN ARROW buttons to change
setpoint temperature.
4.
Setpoint temperature changes one degree with each
successive press of UP or DOWN ARROW buttons.
Holding button down will changes temperature rapidly.
5.
Place setpoint temperature above room temperature.
6.
Electric or hot water heat energizes and heating
continues as long as setpoint remains above room
temperature.
7.
Heating LED illuminates as long as unit is calling
Heating mode.
8.
When room temperature is satisfied for sixty (60)
seconds and two (2) minute minimum on-time has
expired, electric heat switches off.
9.
See Fan Operation, see Page 30.
Dry Mode
Dry mode removes humidity from air while maintaining
specific setpoint temperature. This is done by cycling
cooling mode. Dry mode will NOT maintain specific
humidity level. Fan remains on continuously at low speed
while in Dry mode.
Dry mode operation, turn unit on via POWER button.
1.
Select Dry mode via MODE button.
2.
Room temperature and setpoint temperature are
displayed.
3.
Press either UP or DOWN ARROW buttons to change
setpoint temperature.
4.
Setpoint temperature changes one degree with each
successive press of UP or DOWN ARROW buttons.
Holding button down will change temperature rapidly.
5.
Place setpoint temperature at desired room
temperature.
6.
Depending on difference between room temperature
and setpoint temperature, water valve will either
remain open continuously, cycle open/closed, or remain
closed.
7.
If room temperature is greater than setpoint
temperature by more than two (2) degrees, unit runs
Cooling mode continuously .
8.
If room temperature is within ± two (2) degrees of
setpoint, unit cycles cooling on seven (7) minutes and
off seven (7) minutes to remove humidity from air
while not over cooling room.
9.
If room temperature is less than setpoint temperature
by more than two (2) degrees, cooling remains off.

Control must first be configured properly, heat source –
ON. See Figure 37, Page 26.
Auto changeover mode, cassette will operate in either
Cooling mode or Heating mode. Control selects mode
of operation dependent upon setpoint temperature,
room temperature and differential setting selected in
configuration mode.
Auto changeover mode, turn unit on via POWER button.
1.
Select Auto mode via MODE button.
2.
Room temperature and setpoint temperature are
displayed.
3.
Press either UP or DOWN ARROW buttons to change
setpoint temperature.
4.
Setpoint temperature changes one degree with each
successive press of UP or DOWN ARROW buttons.
Holding button down changes temperature rapidly.
5.
