SEqUENCE Of OpERATION
Place the setpoint temperature above
room temperature. The outdoor unit will
energize in heat pump mode and heat
-
ing will continue so long as the setpoint
remains above room temperature. The
Heating LED will illuminate so long as the
unit is calling
heating Mode . When the
room temperature has been satisfied for
at least sixty (60) seconds and the two (2)
minute minimum on time has expired, the
electric heat will switch off. The fan will op
-
erate as described in “Fan Operation”.
OpTIONAL HEAT pUMp WITH ELECTRIC
heat (2-stage heatIng):
For heat pump operation with electric heat
the control must first be configured prop
-
erly (Heat source – ON, Heat pump – ON).
See: Configuration Mode.
For heat pump operation with optional
electric heat, turn the unit oN via the
PoWER/SEND button. Then select
heat-
ing Mode via the MoDE button.
The room temperature and setpoint tem
-
perature will be displayed. Press either
the UP or DoWN ARRoW buttons to
change the setpoint temperature. The set
-
point temperature will change by one (1)
degree with each successive press of the
UP or DOWN ARROW buttons. Holding
the button down will change the tempera
-
ture rapidly.
Place the setpoint temperature above
the room temperature by one (1) degree.
The compressor will start and heating will
continue for a minimum of two (2) minutes
and as long as the setpoint remains above
room temperature. The Heating LED will
illuminate so long as the unit is calling for
heating Mode.
When the room tempera
-
ture has been satisfied for at least sixty
(60) seconds and the two (2) minute mini
-
mum on time has elapsed, the compres
-
sor will switch off. The fan will operate as
described in “Fan Operation”.
Next, place the setpoint temperature
above the room temperature by at least
two (2) degrees. The compressor will start
and, the electric will also energize after a
thirty (30) second delay, thus two-stage
heating. The electric heat will run for a
minimum of two (2) minutes and until the
deviation between room temperature and
setpoint temperature is less than two (2)
degrees. At that time the electric heat will
switch off and the heat pump (compres
-
sor) will take over the heating demand.
The electric heater will not re-start until a
three (3) minute delay has elapsed. Once
the room temperature is satisfied and the
two (2) minute minimum run time has
elapsed, the compressor will cycle off. The
compressor will not re-start until a three
(3) minute delay has elapsed. The fan will
operate as described in “Fan Operation”.
DRY MODE:
Dry Mode
will remove humidity from the
air while maintaining a specific setpoint
temperature. This is done by cycling
Cool-
ing Mode. Dry Mode will NoT maintain a
specific humidity level. The fan will remain
on constantly at low speed while in
Dry
Mode.
for Dry Mode
operation, first turn the unit
oN via the PoWER/SEND button. Se-
lect
Dry Mode via the MoDE button. The
room temperature and setpoint tempera
-
ture will be displayed. Press either the UP
or DoWN ARRoW buttons to change the
setpoint temperature. The setpoint tem
-
perature will change by one (1) degree with
each successive press of the UP or DOWN
ARROW buttons. Holding the button down
will change the temperature rapidly.
Place the setpoint temperature at a de
-
sired room temperature. Depending on
the difference between room temperature
and setpoint temperature the compressor
will either remain on constantly, cycle on/
off, or remain off.
