Symptom
My thermostat is reading in Celsius.
How do I change it to Fahrenheit?
My display light does not work. Can it be
fixed or replaced?
My setpoint temperature is flashing.
What does that mean?
How can I get a copy of the Operating
Manual for my thermostat?
Corrective Action
Your thermostat display can be set to display temperature in Fahrenheit or
Celsius. This option can be set in the INSTALLER/CONFIGURATION MENU
of your thermostat. See page 6 step 12.
Because it is soldered to the circuit board it is not possible to repair or
replace.
When the thermostat compressor time delay occurs it will flash the setpoint
for about five minutes. This is intended to help protect the compressor from
short cycling.

Lockout Code
Why won't my 2nd or 3rd
stage come on?
First Stage is keeping up with
demand
CAUTION: This resets the thermostat to factory
default settings of the configuration menu. After
performing this reset, the thermostat will require
configuration again. Be sure that you know the
required configuration settings before resetting.
With the thermostat in any mode, press

the same time to enter the configuration menu at the
point where the lockout code is to be entered. Press
and and SYSTEM button at the same time to
reset the lockout code, unlock the keypad and reset
all configuration menu settings.
Your thermostat is designed to determine the
optimum time to activate the second stage. Simply
raising the temperature in heating or lowering it in
cooling will not always force the thermostat to bring
the second stage on quickly. There is a time delay
from 0-30 minutes depending on the performance of
the first stage of the system.
