INSTALLER/CONFIGURATION MENU
1 . This control can be configured for:
MS2
– Multi-Stage System - No Heat Pump (2 heat/2
cool)
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 27) (4 heat/2 cool)
SS1
– Single Stage System and 3 wire zone systems see
wiring diagrams .
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 thermostat
switches the option to GAS.
3 .
O/B Terminal selection
– Selects the operation of the
reversing valve (when item 1 is set to HP1 or HP2 only) .
When set to "O" the changeover valve will be energized
in COOL to accommodate the majority of heat applica-
tions . If the heat pump requires the changeover valve to
energize in HEAT, select "B" .
4 .
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 . 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 .
5 .
System Switch Configuration (MS2/SS1)
– This ther-
mostat is configured for Heat and Cool with Auto change-
over default (Cool-Off-Heat-Auto) . It 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/
HP2)
, the system switch configuration will have an
additional mode available,
Em
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:
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 set-
point 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
change to slow cycling (SL, Cr), press touch keys or
toggle between FA & SL . The cycle rates are below:
Mode
Fast rate
Slow rate
Heat (SS1, MS2)
0 .6°F
1 .5°F
Cool (SS1, MS2)
1 .2°F
1 .7°F
Heat Pump (HP1, HP2) 1 .2°F
1 .7°F
Emer Heat (HP1, HP2)
0 .6°F
1 .7°F
10 .
Select Compressor Lockout (CL)
– Selecting (CL On)
will cause the thermostat to wait 5 minutes between cool-
ing cycles . This is intended to help protect the compressor
from short cycling . Some of the newer compressors have
a time delay built in and do not require this feature to be
activated in the thermostat . Your compressor manufactur-
er 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 (dL)
– In low lighting con-
ditions, 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 . You can toggle the selection between HI
and LO .
13 .
Select Temperature Display Adjustment 5 LO to 5 HI
This allows you to adjust the room temperature display
by -5°F to +5°F in 1° steps . Your thermostat was accu-
rately calibrated at the factory, however you have the
option to change the display temperature value to match
the previous thermostat, if you so prefer .
