INSTALLER/CONFIGURATION MENU
10) 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 .
11) 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 ac-
curately calibrated at the factory, however you have the
option to change the display temperature value to match
your previous thermostat, if you so prefer .
12) Select °F or °C Readout – Select the desired temper-
ature unit by pressing or . Factory default is °F .
13) Select Audio Prompting (Beeper) On or Off – Factory
default setting is on (b, On) . If you wish to turn off the
beeper select OFF .
14) 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 .
15 & 16) Select Automatic Schedule – With just one touch
of the Auto Schedule key this feature allows you to pro-
gram a desired comfort temperature into all the program
periods along with a 6° set back for night periods of both
Heat and Cool programs . Factory default is "On" for both .
When Heat AS On and Cool AS On are activated while
in Heat or Cool mode, select desired setpoint tempera-
ture and press Auto Schedule . Auto Schedule will flash,
press it again to copy . This value will be copied into all
the morning, day and evening program periods . The night
program periods will be with a 6°F set back .
17) Select Cool Savings™: With Cool Savings™ enabled,
the thermostat will make small adjustments to the sensed
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 tempera-
ture will feel comfortable . After 20 minutes of run time, the
thermostat will start decreasing the sensed temperature
in steps of less than one degree as the system contin-
ues to run . These adjustments will eventually 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 adjustments,
the display will flash “CoolSavings” . The amount of the
adjustments to the sensed temperature is dependent 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 sensed temperature are reversed until sensed tem-
perature returns to normal and “CoolSavings” no longer
flashes.
1) 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 thermostat switches
the option to ELE.
2) Programs per week – This control can be configured for
7 independent day or 5/1/1 day programming or nonpro-
grammable 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-programmable mode,
the step for EMR will be skipped, as this feature will not
be available in this mode .
3) 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 .
4) System Switch Configuration – This thermostat is con-
figured for Heat and Cool with Auto changeover default
(Cool-Off-Heat-Auto). Can be configured as Heat & Cool
(Cool-Off-Heat), or Heat Only (Off-Heat), or Cool Only
(Cool-Off) .
5) 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 . Cool-
ing allows more time per °F, because it takes longer to
reach temperature .
6 & 7) Cycle Rate Selection – The factory default setting
is fast cycle (FA Cr) in all modes (Heat, Cool) . 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
8) 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 thermostat . Your compres-
sor 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 setpoint for up to five minutes.
9) 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 .
