Sequence of Operation – Wall mounted thermostat mode

Heat Pump with Electric Heat: Select a thermostat that is compatible with a single stage cooling, two-stage heat, heat pump system. The thermostat should have “R”, “Y”, “O”, “W (or W2)” and “G” terminals. The thermostat may also have a “C” terminal. If the indoor unit is not equipped with electric heat then a single stage heat pump thermostat is ad- equate.

Fan Operation

The indoor unit utilizes a two-speed mo- tor. The FAN button will allow the selection of the desired fan speed setting (High or Low). The wall thermostat will control the call for fan operation (On or Off) through the low volt terminals “R” and “G”.

After the room thermostat has been sat- isfied and the call for fan has been re- moved, the indoor fan to remain on for an additional 60 seconds. This increases efficiency by pulling the remaining energy from the unit.

Some thermostats are equipped with an “AUTO/ON” fan switch. When this switch is placed in the “ON” position the indoor fan will run continuous. When the switch is in the “AUTO” position the indoor fan will cycle with the call for heating or cooling.

Cooling operation:

The wall thermostat will control the call for cooling operation (On or Off) through the low volt terminals “R” and “Y”. After con- necting the thermostat to the unit, place the system switch in Cool mode. Adjust the set-point temperature below the room temperature. The compressor and fan motors will start and cooling will begin. Next, place the set-point temperature above the room temperature. The outdoor condenser will stop. The fan will operate as described in Fan Operation.

Note: Once the cooling has cycled off or following a power outage, the com- pressor will not start for at least three minutes (See Short Cycle Protection).

Electric heat operation:

For remote thermostat operation with electric heat the control must first be configured properly (Remote – ON, Heat source – “ON”). See: Configuration Inter- face mode.

The wall thermostat will control the call for electric heat operation (On or Off) through the low volt terminals “R” and “W”. After connecting the thermostat to unit, place the system switch in Heat mode. Adjust the set-point temperature above the room temperature. The electric heat will ener- gize along with the indoor fan motor. Heat- ing will continue so long as the set-point remains above room temperature. Next, place the set-point temperature below room temperature. The Electric heater will switch off and the indoor fan will remain on for an additional sixty seconds.

Note: Once the heating has cycled off or following a power outage, the heat- ing will not resume for at least three minutes (See Short Cycle Protection).

Optional Heat pump with Electric heat (2-stage heating):

For remote thermostat operation for two stage heating including a heat pump condenser and indoor electric heat, the control must first be configured properly (Remote – ON, Heat source – “ON”). See: Configuration Interface mode.

The wall thermostat will control the call for electric heat operation (On or Off) through the low volt terminals “R” and “W” for compressor (heat pump) heating through terminals “R” and “Y”. After connecting the two stage heating thermostat to the unit,
