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.

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.
There is no need to select a time to stop a programming period. Starting a
new programming period will stop the previous program period.
Unless the thermostat appears to be damaged it will follow the program that is
in the memory. The most common reason a thermostat will appear not to be
following the program is a programming error. Verify that the AM or PM
settings are correct for each period. Also verify that the Day of the week is set
correctly. Models with EMR (Energy Management Recovery) start early to
make the temperature they are programmed for by the time specified in the
program. See the CONFIGURATION MENU on page 6 step 3.
Any time you wish to turn your system off, simply press the SYSTEM button
until “OFF” is displayed. This will not affect your thermostat’s programming in
any way. To turn the system back on, press the SYSTEM button to HEAT or
COOL and press RUN. The system will begin operating according to the
current thermostat program. See under OPERATION page 8 & 9.
Because it is soldered to the circuit board it is not possible to repair or
replace.
No. This thermostat has permanent memory, although you will have to reset
your clock.
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.

You can perform software reset by pressing
and SYSTEM buttons
simultaneously when SYSTEM mode is OFF. See “Forget Keypad Lockout
Code” under “TROUBLESHOOTING” for details.
