Compressor
Short Cycle Protection.
Your thermostat can be configured to
protect your system against premature
compressor failure by “locking out”
the compressor. This ensures that the
compressor will stay off for at least
five minutes on each cycle. When the
thermostat is in compressor lock-out,
the word COOL will flash. During this
period, the compressor will not be
energized. See the installation
instructions.
Service Button Menu
The Service button allows setting of
maintenance reminders for three
optional equipment accessories
typically used with forced air heating/
cooling systems. The three accessories
humidifier, air filter, and UV light are
designed to enhance indoor air quality.
A humidifier will add humidity when
conditions would normally make the
indoor air uncomfortably dry. Air
filters are designed to clean the air
through a forced air system. These
accessories require routine mainte-
nance to provide optimum perfor-
mance. The service button mainte-
nance reminders are designed so that
they can be customized to the
requirements of each accessory. If your
system is a forced air system you may
have none or all three accessories. The
fourth maintenance reminder is for
routine servicing of your system by a
professional HVAC contractor. The
fourth reminder option may be used in
lieu of or in conjunction with the other
reminders. If you’d prefer having a
professional service your system, the
Routine Maintenance Reminder is the
only reminder you’ll need to set. To
disable a feature that was previously
selected, press TIME
BACK
button to
show either REM PAD TIME, REM
FLTR TIME, REM UV TIME, or
REM SERV TIME and then press the
