UNIT MOUNTED INFRARED COMPATIBLE CONTROL
COOLING ONLY OPERATION
For cooling operation first turn the unit on via the
On/off
button. Select
Cool
mode via the
Mode
button. The room
temperature will be displayed. Then, by depressing either
the
Up
or
Down
arrow once, the setpoint temperature will
appear. The setpoint temperature can then be changed with
each successive press of the
Up
or
Down
arrow buttons or
by holding the button in. Place the setpoint temperature
below the room temperature. The compressor will start and
cooling will continue for a minimum of two minutes and as
long as the setpoint remains below room temperature.
(On
initial startup or if power is lost, there is a three-minute de-
lay between compressor re-starts.)
Once the room temperature is satisfied and the two-
minute minimum run time has elapsed the compressor will
cycle off. The fan will operate as described in “Fan Opera-
tion”
(
Figure 5)
.
NOTE: Once the compressor is switched off there is a
three-minute delay before it will re-start.
OPTIONAL ELECTRIC HEAT OPERATION
(Non Heat Pump Condenser Units Only)
For electric heat operation first turn the unit on via the
On/off
button. Select
Heat
mode via the
Mode
button. The
room temperature will be displayed. Then by depressing
either the
Up
or
Down
arrow once, the setpoint tempera-
ture will appear. The setpoint temperature can then be
changed with each successive press of the
Up
or
Down
arrow or by holding the button in. Place the setpoint tem-
perature above room temperature. The electric heat will en-
ergize and heating will continue as long as the setpoint
remains above room temperature. Once the room tempera-
ture is satisfied the electric heat will cycle off. The fan will
operate as described in “Fan Operation”
(
Figure 5)
.
Figure 5
has been off for ten minutes, the fan will cycle on for 60
seconds. This is done so the microprocessor can sample
the room air and also helps eliminate room temperature
stratification.
When the unit is in
Dry
mode the fan speed will remain
constant at
low
speed. While the unit is in
Fan
mode,
Auto
is bypassed and only
High
or
Low
are available (
