5) System Switch Configuration (MS2/SS1) – This

(Off-Heat), or Cool Only (Cool-Off).

or
touch keys to select the feature, OFF.
17 & 18) Select Automatic Schedule – This feature allows
programming a “Comfort Temperature” into all program
periods with the Auto Schedule key. When Heat AS (for
Heat mode) or Cool AS (for Cool mode) is selected On,
the Auto Schedule feature is ready to be set. Off
indicates that the feature is not ready to be used or a
“Comfort Temperature is already set. See Auto Schedule
in Programming section.
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.
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.
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
Heat
Cool
Fast rate
0.6°F
1.2°F
Slow rate
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.
