°F vs. °C Display
The unit is factory congured to display all temperatures in degrees
Fahrenheit (° F). To switch to degrees Celsius press the ‘Fan Only’ and
‘Low Fan’ buttons simultaneously for three seconds. The display will show
a ‘C’ as acknowledgement of the change. To revert back to ° F press the
‘Fan Only’ and ‘Low Fan’ buttons simultaneously for three seconds. The
display will show an ‘F’ as acknowledgement of the change.
Cooling Mode
Pressing the ‘Cool’ button while the unit is in any mode, including off,
will put the unit into cooling mode. Adjust the temperature readout to the
desired room temperature and the unit will cycle the compressor on and
off to maintain a comfortable room. The compressor will come on anytime
that the room temperature is 1.8° F above the desired temperature. The
fan operation is dependent on the fan mode selected, either continuous
or cycling. See Fan Mode for fan cycle control.
Heating Mode
Pressing the ‘Heat’ button while the unit is in any mode, including off, will
put the unit into heating mode.
Heat Pump Models (PDH)
When the ‘Heat’ button is pressed initially the unit will energize the electric
resistance heat to quickly bring the room to the set temperature. When the
desired room temperature falls 1.8° F below the desired set temperature the
unit will cycle the compressor on and operate as a heat pump to maintain
the room temperature while running more efciently than resistance heat
only models. If the room temperature should fall more than 5° F from the
set temperature the unit will run the resistance heater. The fan operation
is dependent on the fan mode selected, either continuous or cycling. Dip
switch 3 controls the fan mode, see page 23 for setting.
utes the unit will operate the resistance heaters and not the compressor.
When the outdoor coil temperature reaches ° F the compressor will be
allowed to operate again.
Heat/Cool Models (PDE)
After pressing the ‘Heat’ button, adjust the temperature readout to the
desired room temperature and the unit will cycle the resistance heat on
and off to maintain a comfortable room. The heater will come on anytime
that the room temperature is 1.8° F below the desired temperature. The
fan operation is dependent on the fan mode selected, either continuous
or cycling. Dip switch 3 controls the fan mode, see page 23 for setting.
Emergency Heat Operation
In the event of a compressor failure in heat pump mode the compressor may
be locked out to provide heat through the resistance heater. This feature
ensures that even in the unlikely event of a compressor failure the room
temperature can be maintained until the compressor can be serviced. Dip
switch 1 controls the emergency heat setting, see page 23.
Fan Mode
All units are shipped with fan mode to continuous for cooling and cycle
for heating.
Fan Only
Pressing the ‘Fan Only’ button will run the fan to allow for air circulation
in the room without operating the compressor or heater regardless of the
room or set temperature. The fan speed selection is made by pressing
either the ‘High Fan’, ‘Med Fan’ or ‘Low Fan’ button.
Cycle/Continuous
The owner may choose between fan cycling or fan continuous mode based
on property preference (Note: Even heat monitoring and quiet start/stop
fan delay only operate in fan cycle mode). Fan continuous mode is used
to keep constant airow circulation in the room during all times the unit is
‘ON’. Fan cycle will conserve energy by only operating the fan while the
compressor or electric heater is operating. Dip switch 3-4 controls the fan
mode, see page 23 for setting.
