when SYSTEM switch is in the OFF position).

should be replaced.

The configuration menu allows you to set certain thermostat
operating characteristics to your system or personal requirements.
To enter the configuration menu, with SYSTEM switch in OFF
position, hold
and
configuration menu, move the SYSTEM switch from the OFF
position.
2. In the run mode, if the setpoint temperature is manually raised
by 3 F (2 C) or more above the actual temperature with the
TEMPERATURE UP key, and the fast second stage feature is
enabled, FA on, the second stage will energize immediately.
With FA off, second stage will not energize until the setpoint
temperature is 1 F or more above actual temperature for more
than ten minutes.
3. Select Compressor Lockout CL OFF or ON – Selecting CL
ON will cause the thermostat to wait 5 minutes before turning
on the compressor if the heating and cooling system loses
power. It will also wait 5 minutes minimum between cooling and
heating cycles. This is intended to help protect the compressor
from short cycling. Some newer compressors already have a
time delay built in and do not require this feature. Your com-
pressor manufacturer can tell you if the lockout feature is
already present in their system. When the thermostat compres-
sor time delay occurs it will flash the Snowflake and Flame
Icons for about five minutes.
4. Select Temperature Display Adjustment 3 LO to 3 HI –
Allows you to adjust the room temperature display up to 3 higher
or lower. Your thermostat was accurately calibrated at the
factory but you have the option to change the display temperature
to match your previous thermostat. The current or adjusted
room temperature will be displayed on the left side of the display.
