Routing of the thermostat wiring harness must comply with
all local and national electrical codes. Collect any excess
thermostat harness in the air conditioner mounting
compartment. Be sure to secure the excess wiring within the
compartment. Coiling the excess harness into 3" diameter
circles or larger is acceptable.
THERMOSTAT MOUNTING
Follow the instructions packed with the thermostat to select a
location for thermostat mounting. Pay particular attention to
choose a location which is not totally isolated from air
currents and is not subject to direct discharge from an air
register.

door.
3.
Before beginning the checkout procedure, thoroughly
read the instructions in either the thermostat
installation instructions or in the owners manual
provided with this product.
Keep in mind that the wall thermostat provides a
3 minute delay between off and on cycles.
There is also a 30 second delay between 1
st
and 2
nd
stage cooling. This is to prevent both compressors
from starting simultaneously. To insure that the
thermostat calls for both 1
st
and 2
nd
stage cooling,
verify that the cool setpoint is well below actual
indoor temperature.
4.
After complying with steps 1 through 3, engage
power to all systems and begin checkout procedure.

Test each thermostat function such as fan modes and
cool modes to insure proper operation.
