with 1 (1°) being the least amount of adjustment and 6 (6°)
being the most amount of adjustment. Default value is 3.
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 onthe 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. Adjusting 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.
To turn this feature on in the Cool mode press Cool

Energy Management Recovery (E) On enables the ther-
mostat to start heating or cooling early to make the building
temperature reach the program setpoint at the time you
specify. Heating will start 5 minutes early for every 1° of
temperature required to reach setpoint.
Example

Example

Example: E On is selected and your heating is pro-
grammed to 65° at night and 70° at 7 AM. If the building
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.

5, 6 & 7) Cycle Rate Selection

Cycle Rate Selection

Cycle Rate Selection – The factory default setting for

Heat and Cool modes, SS1, MS2, is medium cycle (ME).
For Heat Pump, HP1, HP2, the default setting is medium
(ME). For Emer (Aux) the default setting is fast cycle
(FA).To change cycle rate, press the

key.

Cycle rate differentials for different settings are:

CL ON will cause the thermostat to wait 5 minutes between
cooling cycles. This is intended to help protect the compres-
sor from short cycling. Some newer compressors 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.

this thermostat requires a "B" terminal, to energize the
changeover relay in HEAT, the O/B option should be set at
"B" position.
