COOlINg Operation
Optional wired wall controller controls call for cooling
operation (On or Off).
After connecting thermostat to unit, place system switch in
Cool mode.
• Adjust set-point temperature below room
temperature.
• Compressor and fan motors start and cooling begins.
Place set-point temperature above room temperature.
• Outdoor condenser stops.
• Fan operates as described in FAN operation.
Once cooling has cycled off or following power outage,
compressor does not start for at least 3 minutes (short-
cycle protection).
fAN Operation
Indoor unit utilizes 3 speed motor.
• Unit controller FAN button allows selection of desired
fan speed setting (High, Medium or Low).
• Wired wall controller controls call-for-fan operation
(On or Off).
After room temperature has been satisfied and call for fan
has been removed, indoor fan remains on for additional
60 seconds. This increases efficiency by pulling remaining
energy from the unit.
Optional wired wall controllers are equipped with AUTO/ON
fan switch.
• When switch is placed in ON position, indoor fan runs
continuously.
• When switch is in AUTO position, indoor fan cycles
with call for heating or cooling.
When power is first applied to control or after power outage
there is 3 minute delay before compressor or electric heat
energize. This is to protect unit from short cycling due to
loss of power.

eleCTRIC HeAT Operation
Optional wired wall control operation with electric heat,
control must be configured properly. "Wired Wall Control
Heat source ON". See Table 7, Page 27
.
Wired Wall Controller controls call for electric heat opera
-
tion (On or Off).
After connecting controller to unit, place system switch in
Heat mode.
• Adjust set-point temperature above room
temperature.
• Electric heat energizes with indoor fan motor.
• Heating continues so long as set-point remains above
room temperature.
Place set-point temperature below room temperature.
• Electric heater will switch off and indoor fan remains
on for additional 60 seconds.
Once heating has cycled off or following power outage,
heating does not start for at least 3 minutes (short-cycle
protection).
optional
Heat pump With Electric heat (Two-
stage Heating)
Optional wired wall controller operation for two stage
heating including heat pump condenser and indoor electric
heat, control must be configured properly. Wired Wall
Control, heat source ON". See Table 7, Page 27
.
Wired Wall Controller controls call for electric heat
operation (On or Off).
After connecting controller to unit, place system switch in
Heat mode.
• Adjust set-point temperature above room
temperature. Compressor and fan motors start and
heating begins.
• Electric heat will energize when deviation between
room temperature and set point temperature is high
enough to call for second stage heating.
Place set-point temperature below room temperature.
• Outdoor condenser and electric heat stop while indoor
fan remains on for additional 60 seconds.
Once heating has cycled off or following a power outage,
heating does not start for at least 3 minutes (short-cycle
protection).
