3) Select Cool Savings™ value – Selects the amount of
adjustment for the Cool Savings™ feature in Cool mode
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 tem-
perature 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.
To turn this feature on in the Cool mode press Cool
Savings. The display will show “Save” next to the set-
point temperature. When Cool Savings is making adjust-
ments to the room temperature display “Save” will be
fl ashing and the displayed room temperature may vary
within the adjustment range you selected.
If "Save" is not displayed and this feature is OFF, no
change will occur when the cooling system is continuously
running during periods of high demand.
4) Energy Management Recovery: (this step is skipped if
confi gured to be non-programmable).
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 approximately 5 minutes early
(15 minutes for heat pump) for every 1° of temperature
required to reach setpoint.
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 approxi-
mately 15 minutes per degree, because it takes longer to
reach set temperature.
