OPERATION

Figure 6 – Thermostat display, buttons and switches

Before you begin programming your thermostat, you should be
familiar with its features and with the display and the location
and operation of the thermostat buttons. Your thermostat
consists of two parts: the thermostat cover and the base. To
remove the cover, pull it straight out from the base. To replace
the cover, line up the cover with the base and press until the
cover snaps onto the base.

Fast or Slow Cycle Selection

Fast or Slow Cycle Selection – The factory default setting
is fast cycle, which cycles 1st stage at approximately 1.2°F
and 2nd stage 0.75°F. If you prefer slow cycle, press the
temperature key to change to SL. The 1st stage and 2nd
stage would be 1.5°F and 1.2°F respectively.

3) Select Compressor Lockout CL OFF or ON

Select Compressor Lockout CL OFF or ON

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 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 about five minutes.
