INSTALLER/CONFIGURATION MENU
1) This control can be configured for:
SS1 – Single Stage System
HP1 – Heat Pump with one stage of compressor
(2 heat/1 cool)
(Dual Fuel see menu item 25)
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 (SS1/HP1) – 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), 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
between FA & SL . The cycle rates are as below different
selections:
Mode
Fast rate
Heat
0 .6°F
Cool
1 .2°F
Emer
1 .2°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 .
When C terminal is not powered (battery only), dL On
enables the momentary backlight whenever a key is
pressed .
12) Select Backlight Intensity – This thermostat has the
ability to provide two selectable intensities of the back-
light: HI and LO . Using
toggle the selection between HI and LO .
13) Select Temperature Display Adjustment 4 LO to 4 HI
This allows you to adjust the room temperature display
by an amount in the range of -4°F to +4°F in 1° steps by
using the
or
touch keys . Your thermostat was
accurately calibrated at the factory, however you have the
option to change the display temperature value to match
your previous thermostat, if you so prefer .
14) Select °F or °C Readout – Select the desired temper-
ature unit by pressing
15) Select Audio Prompting (Beeper) On or Off – Factory
default setting is on (b, On) . If you wish to turn off the
beeper select OFF .
16) Select Daylight Saving Time Calculation – This feature
will allow the thermostat to calculate the DST automati-
cally and apply it to the Real Time Clock display . Default
On . Use
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 in-
dicates that the feature is not ready to be used or a
"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.
