Example: E On is selected and your heating is pro-
grammed to 65° at night and 70° at 7 AM. If the build-
ing temperature is 65°, the difference between 65° and
70° is 5°. Allowing 5 minutes per degree, the thermostat
setpoint will change to 70° at 6:35 AM. Cooling allows
more time per degree, because it takes longer to reach
set temperature.

9) Select Compressor Lockout CL OFF or ON – Select-
ing CL ON will cause the thermostat to wait 5 minutes
between cooling cycles. This is intended to help protect
the compressor from short cycling. Some newer com-
pressors 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 oc-
curs, it will flash the setpoint for up to five minutes.
To reset the combination code and unlock the keypad if
the code is forgotten, see troubleshooting section.

value is 0 which disables this feature. Cool Savings is
an optional energy saving feature that can reduce your
cooling costs. It is based on the principal that lower
indoor humidity makes a slightly higher temperature
feel more comfortable. Cool Savings operates during
periods of high demand which normally occur on the
hottest summer days when a cooling system may run
for hours to reach the thermostat setting. Long cooling
run times also lower the indoor humidity. Cool Savings,
very slowly, adjusts the setpoint temperature to make the
setpoint closer to the displayed room temperature, to a
maximum of the number of degrees you select. Adjust-
ing the setpoint temperature over a long cooling run time
allows the system to reach your set temperature and turn
off. The room temperature will actually be higher than
the thermostat displays but the reduction in humidity will
allow comfort at the slightly higher temperature.
