INSTALLER/CONFIGURATION MENU
6 & 7)
Fast or Slow Cycle Selection
– The factory default
setting for Heat is fast cycle (FA), which cycles heat at
approximately 0.6°F. If you prefer slow cycle, press the
or
key to change to SL. Heat will cycle at approxi-
mately 1.2°F. For Cool the default setting is fast cycle
(FA), which cycles cool at approximately 1.2°F. If you
prefer slow cycle, press the
or
key to change to SL,
cool will cycle at approximately 1.7°F.

Select Compressor Lockout CL OFF or ON
– Selecting
CL ON will cause the thermostat to wait 5 minutes be-
tween cooling cycles. This is intended to help protect the
compressor from short cycling. Some newer compres-
sors already have a time delay built in and do not require
this feature. Your compressor manufacturer can tell you if
the lockout feature is already present in their system.
When the thermostat compressor time delay occurs, it
will flash the setpoint for up to five minutes.
When CL is ON and 24V common (C) is connected, the
lockout feature will prevent compressor start after a 24V
power interruption of less than 5 minutes. This will
assure a 5-minute delay to prevent premature compress-
or failure.
9)
Select Backlight Display
– The display backlight
improves display contrast in low lighting conditions.
When the
C
terminal is powered, selecting backlight (dL
ON) will turn the light on continuously. Selecting backlight
OFF will turn the light on momentarily after any key is
pressed. When the
C
terminal is not powered, this
selection has no effect.
