“Comfort Temperature is already set . See Auto Schedule
in Programming section .
19)
Select Cool Savings™
: With Cool Savings™ enabled,
the thermostat will make small adjustments to the
setpoint temperature during periods of high demand to
reduce AC system running time and save energy . When
the cooling system has been running for more than 20
minutes, humidity in the home will be lower and a higher
temperature will feel comfortable . After 20 minutes of run
time, the thermostat will start increasing the setpoint
temperature in steps of less than one degree as the
system continues to run . These adjustments will eventu-
ally cause the system to satisfy the thermostat to turn the
system off and reduce the energy consumption . When
the Cool Savings™ feature is active and making ad-
justments, the display will flash
“Cool Savings”
. The
amount of the adjustments to the setpoint temperature
is dependent on the Cool Savings™ value that is set, 1
being the least adjustment and 6 being the most adjust-
ment . With this feature set to OFF, no change will occur
when the AC system is continuously running during the
periods of high demand . Periods of high demand will nor-
mally occur during the late afternoon and early evening
on the hottest days of the summer . As demand lessens
the adjustments to setpoint temperature are reversed
until setpoint temperature returns to normal and
“Cool
Savings”
no longer flashes.
1) This control can be configured for:
MS2 – Multi-Stage System (2 heat/2 cool)
HP1 – Heat Pump with one stage of compressor
(2 heat/1 cool)
HP2 – Heat Pump with two stage compressor or two
compressor system, Gas or Electric backup; (Dual Fuel
see menu item 26) (3 heat/2 cool)
SS1 – Single Stage System (3 wire zone see wiring
diagram 37-6808A)
2) GAS or Electric (ELE) fan operation . If the heating
system requires the thermostat to energize the fan,
select ELE . Select GAS if the heating system energizes
the fan on a call for heat .
Note: Resetting the thermo-
stat switches the option to ELE.
3)
Programs per week
– This control can be configured for
7 independent day or 5/1/1 day programming or non-
programmable modes . Default is 7-day mode . The
display indicates
"7 Days"
as default . Other options
"5
Days"
or
"0 Days"
can be selected by pressing touch
keys, or . If
"0 Days"
is selected for non-program-
mable mode, the step for EMR will be skipped, as this
feature will not be available in this mode .
4)
Program Steps per day
– This control can be configured
for 4 or 2 program steps per day . Default is
"4 PS"
and
can be toggled between 4 PS and 2 PS by pressing
the or touch keys .
5)
System Switch Configuration (MS2/SS1)
– This ther-
mostat is configured for Heat and Cool with Auto change
-
over default (Cool-Off-Heat-Auto). Can be configured as
Heat & Cool (Cool-Off-Heat), or Heat Only (Off-Heat), or
Cool Only (Cool-Off) .
When the control is in heat pump configuration
(HP1/
HP2)
, the system switch configuration will have an
additional mode available namely,
Emer
for
Emergency
Mode
.
6)
Energy Management Recovery (EMR)
– (this step is
skipped if configured as non-programmable).
When set to "On" causes the thermostat to start heating
or cooling early to make the building temperature reach
the program setpoint at the time you specify .
Example:
Let us say, the heating program is 65°F at
night and 70° at 7 AM . If the building temperature is 65°F,
the difference is 5°F . Allowing 5 minutes per °F rise, the
thermostat setpoint will change to 70° at 6:35 AM .
Cooling allows more time per °F, because it takes
longer to reach temperature .
7, 8 & 9)
Cycle Rate Selection
– The factory default setting
is fast cycle (FA Cr) in all modes (Heat, Cool, Emer) . To
slow cycling (SL, Cr), press touch keys or toggle
between FA & SL . The cycle rates are as below different
selections:
Mode
Fast rate
Slow rate

1 .7°F
Emer

10)
Select Compressor Lockout (CL)
– Selecting 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 of the newer
compressors have already got a time delay built in and
do not require this feature to be activated in the thermo-
stat . Your compressor manufacturer can tell you if this
lockout feature is already present in their system . When
