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
or touch keys you can
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
or . Factory default is °F.
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 ash “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 ashes.
1) This control can be congured 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 congured 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 congured
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 Conguration (SS1/HP1) – This ther-
mostat is congured for Heat and Cool with Auto change-
over default (Cool-Off-Heat-Auto). Can be congured as
Heat & Cool (Cool-Off-Heat), or Heat Only (Off-Heat), or
Cool Only (Cool-Off).
When the control is in heat pump conguration (HP1), the
system switch conguration will have an additional mode
available namely, Emer for Emergency Mode.
6) Energy Management Recovery (EMR) – (this step is
skipped if congured 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
ash the set point for up to ve 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
