OPERATING INSTRUCTIONS
Thermostat styles vary. Some models may not include
the AUTO mode and others will have the AUTO in place
of the HEAT and COOL. Others may include all three.
Please refer to the thermostat’s User Manual for detailed
programming instructions..
The thermostat should be mounted about 5 feet above the
fl oor on an inside wall and not on an outside wall or other
location where its operation may be adversely affected by
radiant heat from fi replaces, sunlight, or lighting fi xtures,
and convective heat from warm air registers or electrical
appliances.
Cooling Operation
1. Set the thermostat system mode to COOL and the
thermostat fan mode to AUTO. See Figure 1.
2. Set the thermostat temperature selector to the desired
temperature level. The outdoor fans, compressors, and
indoor blower will all cycle on and off to maintain the
indoor temperature at the desired cooling level.
Heating Operation
1. Set the thermostat system mode to Heat and the
thermostat fan mode to AUTO. See Figure 1.
2. Set the thermostat temperature selector to the desired
temperature level. The indoor blower and optional
electric heat module will cycle on and off to maintain
the indoor temperature at the desired heating level.
Operating the Indoor Blower Continuously
Set the thermostat fan mode to ON (or CONT on some
thermostat models). See Figure 1.
The indoor blower will start immediately, and will run
continually until the fan switch is reset to AUTO.
The continuous indoor blower operation can be obtained
with the thermostat system switch set in any position,
including OFF. NOTE:
Continuous indoor blower operation
is typically used to circulate the indoor air to equalize a
temperature imbalance due to a solar load, occupancy
loads, or mechanical equipment operation.
