This thermostat has a technician setup menu for easy installer
configuration. To set up the thermostat for your particular application:
1. Hold down the + and - buttons together for 3 seconds.
2. Use the + and - buttons to modify a setting. Use the Fan button to
go back a step and use the system button to go forward a step.
3. To exit Tech Settings, press and hold the + and - button together for
3 seconds or wait 60 seconds.
The swing setting often called
“cycle rate”, “differential” or
“anticipation” is adjustable. A
smaller swing setting will cause
more frequent cycles and a larger
swing setting will cause fewer
cycles.
Cooling
Swing
The cooling swing setting
is adjustable from 0.2˚ to
2˚. For example: A swing
setting of 0.5˚ will turn the
cooling on at approximately
0.5˚ above the setpoint
and turn the cooling off at
approximately 0.5˚ below
the setpoint.

degrees for heating and the thermostat is set at 70
˚
F, the first stage will turn
on at approximately 69.5
