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 adjust-
ments, the display will flash “
Cool Savings” . The amount
of the adjustments to the setpoint temperature is depen-
dent on the Cool Savings™ value that is set, 1 being the
least adjustment and 6 being the most adjustment . 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 normally 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 .
20)
Heat Temperature Limit Range – This feature adjusts
the highest setpoint temperature for heat . The default
setting is 99°F . It can be changed between 62°F and
98°F by pressing the or key . The "
temperature
limit" icon will be displayed to the left of your setpoint
temperature when using this feature . The "
temperature
limit" icon will flash if an attempt is made to adjust the
temperature beyond the range selected .
1) This control can be configured for:
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)
2) GAS or Electric (ELE) fan operation . If the back-up
heating system requires the thermostat to turn on the
fan, keep the default ELE selection . Select GAS if the
back-up heating system manages the fan operation on
a call for back-up heat .
Note: Resetting the thermostat
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 config-
ured for 4 or 2 program steps per day . Default is "
4 PS"

System Switch Configuration – This thermostat is con-
figured for Heat and Cool with Auto changeover default
(Cool-Off-Heat-Emer-Auto) . Can be configured as Heat
& Cool (Cool-Off-Heat-Emer), or Heat Only (Off-Heat), or
Cool Only (Cool-Off) .
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
Heat
0 .6°F
1 .2°F
Cool
1 .2°F
1 .7°F
Emer
1 .2°F
1 .7°F
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 the thermostat compressor time delay is activated,
it will flash the set point for up to five minutes .
11)
Select Continuous Backlight – In low lighting condi-
tions, display backlight improves the display contrast .
When
C terminal is connected, selecting dL On will turn
the backlight on continuously . Selecting dL Off will turn
the backlight on momentarily after any key is pressed .
