INSTALLATION
!

WARNING

Thermostat installation and all components of the
control system shall conform to Class II circuits per
the NEC code.

Remove Old Thermostat
Before removing wires from old thermostat, mark wires for
terminal identification so the proper connections will be made
to the new thermostat.

Installing New Thermostat
1.	 Pull the thermostat body off the thermostat base. Forcing	
or prying on the thermostat will cause damage to the unit.
2.	 Place base over hole in wall and mark mounting hole	
locations on wall using base as a template.
3.	 Move base out of the way. Drill mounting holes. If you	
are using existing mounting holes and the holes drilled	
are too large and do not allow you to tighten base snugly,
use plastic screw anchors to secure the base.
4.	 Fasten base snugly to wall using mounting holes shown	
in Figure 1 and two mounting screws. Leveling is for	
appearance only and will not affect thermostat operation.

Thermostat Power Method

Switch Position/Description

Battery Powered, no 24
Volt system power available.

Switches "On", thermostat
runs on batteries.

Hardwired with Battery
Back-up, for 24 Volt systems
with common connection from
transformer to "C" terminal
on thermostat.

Switches "On", thermostat
runs on power directly from
transformer with battery backup.

*Battery Powered with
Power Stealing Assist,
for 24 Volt systems with no
common connection from
transformer to "C" terminal on
thermostat.

Switches "On", thermostat
runs on batteries and
supplemental power drawn
through the heat or cool circuit.

*Power Stealing Assist is very reliable to increase battery life,
but on a small number of heating or cooling systems with high
impedance electronic modules you may observe one of the
following conditions:
1.	 The furnace draft inducer motor may run with no call for 	
heat.
2.	 The furnace fan may turn on with no call for heat or may 	
not turn off.
3.	 The furnace may not turn off when the call for heat ends.

5.	 Connect wires to terminal block on base using appropriate 	
wiring schematic.

4.	 The air conditioner may not turn off when the call for cool
ends.

6.	 Push excess wire into wall and plug hole with a fire resistant material (such as fiberglass insulation) to prevent	
drafts from affecting thermostat operation.

If the Power Stealing Assist method is not compatible with
your system, place the Power Stealing Switches to "Off". This
cancels Power Stealing Assist, operates the thermostat on
batteries and corrects the condition.

7.	 Carefully line the thermostat up with the base and snap	
into place.

Figure 1 – Thermostat Base Multi-Stage 1F95-1291

Battery Location
2 "AA" alkaline batteries are included in the thermostat at the
factory with a battery tag to prevent power drainage. Remove
the battery tag to engage the batteries.
To replace batteries, set system to OFF, remove thermostat
from wall and install the batteries in the rear along the top
of the thermostat (see Figure 1). For best results, use a
premium brand "AA" alkaline battery such as Duracell® or
Energizer®. If the home is going to be unoccupied for an
extended period (over 3 months) and
is displayed, the
batteries should be replaced before leaving.

Power Stealing Switches
The Power Stealing Switches (Fig. 1) should be left in the
"On" position for most systems. The information in the
following table details the thermostat power method and
switch options.

Dehumidification wiring without an electronically controlled variable speed blower system for
single stage compressor system only.
If you have a single stage compressor system see the diagram below. A relay (customer provided) should be installed
as shown in Fig 7 to switch the fan speed to the next lower
speed on a call for dehumidification from the thermostat. The
reduction in air flow allows the coil to remove more humidity
from the air. The relay should be rated for blower motor load.
Since this configuration reduces the air flow in cooling, the

anti-freeze-up control (White-Rodgers CAFC) or equivalent is
recommended. The CAFC prevents the air conditioning coil
from freezing due to low air flow, dirty filters, low refrigerant
pressure, etc. The CAFC snaps onto the suction line close to
the evaporator coil as possible and breaks the compressor
circuit when the suction line drops below 38­°F and re-make
the circuit at 46°F.

1.	 This control can be configured for:
	 MS2 – Multi-Stage System (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 screen reference number 33) (4 heat/2 cool)
	 SS1 – Single Stage System (3 wire zone 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 applications. 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 nonprogrammable 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 nonprogrammable mode, the step for EMR will be skipped, as
this feature will not be available in this mode.
5.	 Program Steps per day – Not available if configured for
non-programmable. 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.

Option
Selected

6.	 System Switch Configuration (MS2/SS1) – This thermostat is configured for Heat and Cool with Auto changeover 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, Em for Emergency.	
7.	 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 setpoint will change to 70° at 6:35 AM. Cooling allows more
time per °F, because it takes longer to reach temperature.
8, 9 & 10. Cycle Rate Selection – The factory default setting 	
is fast cycle (FA Cr) in all modes (Heat, Cool, Em). To
or
change to slow cycling (SL, Cr), press touch keys
toggle between FA & SL. The cycle rates are below:
	 Mode	
Med	
Slow
	 Heat		
0.6°F	 1.5°F
	 Cool		
1.2°F	 1.7°F
	 Heat Pump	
1.2°F	 1.7°F
	 Emer Heat	
0.6°F	 1.7°F	
11.	 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

7

INSTALLER/CONFIGURATION MENU
a time delay built in and do not require this feature to be
activated in the thermostat. 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.
12.	 Select Continuous Display Lighting (dL) – In low
lighting conditions, display backlight improves the display
contrast. When C terminal is connected, selecting dL On
will turn the display light on continuously. Selecting dL
Off will turn the display light 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.
	 Continuous Display Lighting without common wire
connection – When thermostat is Battery Powered with
Power Stealing assist with low voltage 24V connections
to both W and Y terminals, selecting dL "On" will provide
continuous display light.
Note: If power stealing operation is not compatible with either
the W or Y connection (see page 2), or if only a single
connection to W or Y, continuous display light will be
interrupted when the active power stealing connection (W
or Y) is operating the system. In power stealing mode, the
continuous display light will increase in brightness when a
button is pressed. And on some systems with high impedance, the display light may dim slightly when thermostat
is calling for heat or cool.
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 accurately calibrated at the factory, however you have the
option to change the display temperature value to match
the previous thermostat, if you so prefer.
14.	 Select °F or °C Readout – Changes the display readout
to Celsius or Fahrenheit as required.
15.	 Select Audio Prompting (Beeper) On or Off – Factory 	
default setting is 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 automatically
and apply it to the Real Time Clock display. Default	 is On.
17 & 18.	Select Automatic Schedule – Not available if
configured for non-programmable. 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.
19 & 20. Select Cool Savings™ – Cool Savings™ provides an
energy saving temperature offset (from 1-6 degrees) under
peak cooling load conditions (high outdoor temperatures).
If selected on, Cool Savings™ becomes active when the
air-conditioner runs for periods of longer than 20 minutes.
When active, Cool Savings™ gradually offsets the indoor
temperature display downward. The first 1° of adjustment
will take one hour of continuous air conditioner run time
with subsequent 1° adjustments occurring with each additional half hour of run time (ex for a 2° offset, the air conditioner would need to run continuously for 1 ½ hours). The
offset is limited to the number of degrees you select from
1 up to 6. When an offset starts or is active, “Cool Savings”
will flash on the display.
	 The principle of this energy saving feature takes advantage
of the long air conditioning run times lowering the indoor

8

humidity allowing a slightly higher temperature to feel
comfortable. As the peak load subsides, this feature also
takes advantage of the air conditioner's increased capacity
under more efficient conditions to gradually reduce the offset back to zero and return control to the selected setpoint
temperature.
	 If Cool Savings is selected off, no temperature offset
will occur.
21.	 Compressor Optimization – (Not available on earlier
models) CO provides a delay in circulator fan operation
after the compressor turns on or off. With CO selected
ON, when the compressor turns on (for a call for heat
in heat pump or a call for cool) the fan will be delayed
for five seconds before turning on to allow the air to be
heated or cooled. After the compressor turns off for call
for cool, the fan will continue to run for 20 seconds to
capture additional cooling from the system. If CO is set to
OFF, there will be no delay in fan operation.
22.	 Comfort Alert with Active Protection – (not available
on earlier models) Turn this feature ON to enable active
protection. This allows the thermostat to identify fault
codes sent by the Comfort Alert module when compressor damage is possible and react to those codes by
turning the compressor off. Fault codes from the Comfort
Alert module will flash on the thermostat. (Refer to Comfort Alert Codes in Troubleshooting section.) If a Comfort
Alert module is not connected, or to disable active protection, turn this feature OFF. If a Comfort Alert module is
connected and this feature is turned OFF, the thermostat
will still receive and flash the fault codes from the Comfort
Alert module, but the active protection will not be enabled
to protect the compressor.
23.	 Heat Temperature Limit Range – This feature adjusts
the highest setpoint temperature for heat. The default setting is 99°F. It can be changed to a setting between 62°F
and 98°F. The "temperature limit" icon will be displayed
to the left of your setpoint temperature when using this
feature. The "temperature limit" icon will flash if an
attempt is made to adjust the temperature beyond the
range selected.
24.	 Cool Temperature Limit Range – This feature adjusts 	
the lowest setpoint temperature for cool. The default 	
setting is 45°F. It can be changed to a setting between
46°F and 82°F. The "temperature limit" icon will be displayed to the left of your setpoint temperature when using
this feature. The "temperature limit" icon will flash if an
attempt is made to adjust the temperature beyond the
range selected.
25 & 26.	Keypad Lockout – This step allows you to select
the type of lockout or limited range security required. If no

27 & 28.	Select Fast Second Stage, ON or OFF – Not
available if configured for SS1. Selecting FA ON forces
is
additional heat stages to come on quickly when
used to raise the temperature a few degrees above the
room. Select this setting if you want the heat to increase
quickly when you manually raise the temperature.
	 Selecting FA OFF allows the thermostat to calculate an
optimal time to bring on additional stages of heat. When
is used to raise the setting above the room temthe
perature additional heat stages may come on very quickly
or very slowly (up to 30 minutes later) depending on
recent system performance. Select this setting if you do
not require the additional heat stages to come on quickly
when you manually raise the setting and want to allow the
thermostat to stage based on recent system performance.
	 The Fast Cool feature operates the cooling stages in the
same manner as Fast Heat, On or Off when the temperature is lowered below the room setting.
29. Select Remote Temperature Sensor Enabled – ON
enables a remote sensor connected to thermostat and displays the sensor temperature in the clock digits. OFF (default) indicates no remote sensor connected or enabled.
30. Select Remote Sensor as Indoor or Outdoor – If 30
is enabled, select the remote to be Remote In (Indoor,
F145-1328) or Outdoor Remote (Outdoor, F145-1378).
Default is Remote In.
31. Select Local Sensor Disable – If 31 is selected Indoor,
the thermostat Local Sensor can be disabled so the
displayed temperature will be from the Remote Sensor.
Default is On LS. To disable the Local Sensor, change
selection to OFF LS.
32. Select Dual Fuel Feature (dF) – This feature is applicable only in heat pump modes (HP1, HP2). Enables (On)
or disables (Off) dual fuel feature of thermostat.
33. Select Dual Fuel Temperature – With dF selected On
and outdoor remote sensor available, select the outdoor
temperature the thermostat will use to determine when to
switch to gas heat and shut down the compressor. When
the outdoor temperature falls below the selected temperature the gas heat will begin. Default is 35°, but can be
set in the range of -5 to 50°. A lower setting will delay the
start of gas heat allowing cooler temperature in the home.
34. Select Dual Fuel Setting – With DF selected On and no
outdoor sensor, select the dF setting from 01-09. Factory default is 05. The dF setting influences when second
stage comes on. The factory default creates a separation
of approximately 1°F between stages. Increasing the setting decreases the separation between stages. Decreasing the value increases stage separation. This adjustment allows a small change in the operation of your heat

pump system versus your auxiliary system relative to the
thermostat adjustment. The higher the number the sooner
the auxiliary stage energizes for better comfort. The lower
the number the longer period of time before auxiliary is
energized for more economy.
Note: This setting is not minutes or degrees. It is numeric setting that will influence the internal thermostat calculation
for staging.
35.		Select Compressor Delay (Cd) – After the auxiliary heat
is turned on, the compressor(s) shut down is delayed for
the time selected (in seconds). This delay is factory set to
60, but can be set in the range of 0 to 99.
36.	 Select Auxiliary Off (AO) – Applicable with HP1 or HP2
selected with outdoor sensor. Select the temperature
that will inhibit the auxiliary heating stage. As long as the
outdoor temperature is above the selected temperature,
the auxiliary heat will not turn on. The default setting is
80°(disabled), but can be set in the range of -5 ° to 79°.
Thermostat will not allow a setting at or below the (dF)
dual fuel setting.
	 If indoor temperature drops below 45° because of a possible heat pump malfunction, the thermostat will turn off
the pump and switch to Auxiliary heat. "Call for Service"
will display on screen.
	 There are two ways the thermostat will return to normal
heat pump operation:
•	 Press any key to retry the pump and erase the "call for
service icon.
•	 When setpoint is achieved on Auxiliary, system will
return to heat pump operation on next call for heat.
37.	 Select Programmable Blower Balance Point (bP) –
Applicable with HP1 or HP2 selected, dF On with outdoor
sensor. Requires DHM connection from thermostat to
heat pump system. This feature de-energizes the DHM
terminal to operate the blower at a slower speed for first
stage heat when the outdoor temperature is below the
temperature selected. This circulates warmer air than the
higher fan speed. The default is 80° (disabled), but can be
set from 20° to 79°. Select an outdoor temperature where
the air coming out of the ducts begins to feel cool and the
thermostat will lower the fan speed to circulate warmer air.
38.	 Humidity Display (Hd) – Selecting HD On enables the
display to alternately show the current time and the humidity. If HD is selected OFF, the display will not show the
humidity. (See page 10 for Humidity setpoint range)
39.	 Adjustable Humidity Display – The display will show
the ambient humidity and 00 (default). The setting can
be changed from -20 and LO to 20 and HI. The displayed
humidity will change as the offset is changed. In Run
mode, the displayed humidity will be the ambient humidity
adjusted by the setting selected.
40. Auto Humidity Reduction (HR) – This feature automatically lowers humidity setting when the outside
temperature drops to prevent the interior windows/walls
from reaching the dew point where water condenses on
surfaces. This feature default is OFF. It can be changed
to select LO (low humidity reduction) or HI. To achieve
automatic humidity reduction, the thermostat lowers the
humidity when furnace cycles are long. When the outside
temperature rises, it increases humidity. "LO" indicates a
low amount of humidity reduction.
41. Automatic Humidification (AH) – This feature if enabled
allows for humidification independent of a call for heating
– useful in arid climates where addition humidification in
heating and/or cooling is desired. If enabled, will energize
the humidifier and circulator blower (“G” terminal and the

9

INSTALLER/CONFIGURATION MENU
“HM” terminal) if the actual humidity is below the humidity set point. The display indicates AH. Pressing the
key will cycle the display from OFF to H (feature enabled
in Heat mode) to C (feature enabled in Cool mode) to A
(feature enabled to Auto mode) and back to OFF.
42.	 Cycle Humidifier (CH) – This feature provides an option that reduces the water usage by up to 50% when a
flow-through humidifier is controlled by the thermostat. It
is recommended for use on flow-through humidifiers only.
The display indicates CH (Cycle Humidifier) with the deor
keys will toggle
fault indicating OFF. Pressing the
the display from OFF to On and back to OFF. When CH is
enabled, the humidifier will cycle to turn off for 10 minutes
after it has run for 10 minutes. The blower and/or furnace
will continue to run during the humidifier off period.
43. Programmable Dehumidification Optimal Comfort
Mode (OC) or Optimal Dehumidification (Od) – This
item can be selected to OC (Optimal Comfort mode), Od
(Optimal Dehumidification), or OFF. When Optimal Comfort (OC) is enabled, this feature automatically reduces
indoor humidity with a call for Cooling if humidity is 2%
above humidity setpoint. Humidity is set by pressing the
Humidity key when in the appropriate mode, in this case
or
keys to set desired
Cooling, and pressing the
humidity (range 40% to 95%) level followed by pressing
Humidity key again. This dehumidification feature uses
less energy by maintaining temperature and dehumidifying only when a call for Cooling is required. Optimal Dehumidification (Od) when enabled, this feature automatically reduces indoor humidity with a call for Cooling if
humidity is 2% above setting. Humidity is set by pressing
the HUMIDITY key when in the appropriate mode, in
or keys to set
this case Cooling, and pressing the
desired humidity level followed by pressing Humidity key

again. This dehumidification feature may use more energy
by making dehumidification a priority initiating a call for
cooling if humidity is 2% above desired setting. This
feature may also over-cool the condition space by up to 3
degrees to achieve the desired humidity level. (Note: Both
dehumidification modes operate in Cooling mode only
with a call for cooling)
44 & 45. Change UV Lamp – This feature allows the thermostat to display the words "Change UV Lamp" (Call for
Service of UV bulb) after a set time of UV bulb operation.
This is a reminder to maintain your UV system at optimum level of operation. When enabled, the factory set
interval for "Change UV Lamp" to be displayed is 350
days of UV bulb operation and can be adjusted in 25 day
increments. This should be adjusted with respect to the
bulb’s recommended maintenance schedule.
	When "Change UV Lamp" is displayed, you can clear it
by pressing Clean Display.
46 & 47. Change Humidifier Pad – This feature allows the
thermostat to display the words "Change Pad" after a set
time of humidifier operation. This is a reminder to maintain or clean your humidifier. The factory set interval for
"Change Pad" to be displayed is 100 hours of humidifier
operation. This should be adjusted with respect to the
humidifier’s recommended maintenance schedule.
	When "Change Pad" is displayed, you can clear it by
pressing Clean Display.
48 & 49.	Select Change Filter Run Time – This feature
allows thermostat to display "Change Filter" after a set
time of blower operation. This is a reminder to change
or clean your air filter. This time can be set from 25 to
1975 hours in 25 hour increments. A selection of OFF will
cancel this feature. When "Change Filter" is displayed,

The 1F95-1291 comes configured for 7 day programming and can also be configured for 5+1+1 programming (see configuration section).
Factory settings are listed on Monday, Saturday and Sunday. If you are re-programming a 5+1+1 day schedule, pencil in your
own times and temperatures directly below the factory times and temperatures.
If you are re-programming a 7 day schedule, fill in all lines with the times and temperatures you want.
Keep the following guidelines in mind when planning your program.
•	 In Heating, lower temperatures will save energy.
•	 In Cooling, higher temperatures will save energy.
•	 If you plan on using Auto Changeover, do not program the heating temperature higher than the cooling temperature.

Wired Remote Temperature Sensing
One remote temperature sensor can be installed indoor or
outdoor and connected to the thermostat by a maximum
cable length of 100 meters (300 feet). Terminals +, S and - on
the terminal block allow connection of the remote sensor.
The thermostat must have 24 VAC Common connection to
terminal C for the remote sensor to operate. The remote sensor can be enabled or disabled in the Installer/Configuration
menu, item 29.
When remote sensor, Remote, is selected Off (factory default), no remote sensor is enabled. When remote sensor is
selected On, the next step is to select the remote as indoor,
Remote In, or outdoor, Outdoor Remote. If the remote is selected as Remote In, an additional step will be to select if the

14

temperature shown on the display will be from the thermostat,
LS On, or the remote sensor LS Off.
In normal operation, when a remote sensor is enabled the
time digits of the display will alternate between the time and
the remote temperature for three seconds each. Above the
remote temperature will be Remote, for indoor sensor or
Outdoor Remote, for outdoor sensor. If the remote sensor is
an indoor sensor and the local display has been disabled, the
temperature displayed as the room temperature will be the
remote sensor temperature.
Sensing Range:
Outdoor temperature range is -40oF to 140oF
Indoor temperature range is 32oF to 99 oF

PROGRAMMING
Averaging or Weighting Remote Sensors

Dual Fuel Temperature Setpoint

The thermostat will weight or average the temperature of the
indoor remote sensor with the local sensor in the thermostat
for each program period. The averaging will be active only
when the local sensor and the indoor remote sensor are both
functional and enabled in the Installer/Configuration menu.

When the thermostat is configured for Heat Pump mode and
the Dual Fuel feature is selected on, the thermostat can monitor the outside temperature using remote sensor F145-1378
or use software logic to determine when to switch to gas heat
and shut down the compressor. This eliminates the need for a
fossil fuel kit.

When the thermostat is in the Set Schedule mode, the weight
of the indoor sensor will be shown in the current temperature
digits of the display. The weight will show as A2 (average and
default), H4 (high) or L1 (low). Pressing the
and
keys at
the same time will change the weight for the program period.
The weight of the thermostat sensor is fixed.
In normal operation of the thermostat, the current temperature displayed will be the weighted average of the local
sensor and the remote sensor using the formula (local sensor
weight x local sensor temperature) + (remote sensor weight x
remote sensor temperature) / (local sensor weight + remote
sensor weight).
Example: Local sensor temperature is 80° and the remote
sensor is 70°.
If weight is selected H4, the averaged temperature of 72° will
be displayed.
(1 x 80) + (4 x 70) / 5 = 72°
If weight is selected A2, the average temperature of 73° will
be displayed.
(1 x 80) + (2 x 70) / 3 = 73.3°
If weight is selected L1, the average temperature of 75° will
be displayed.
(1 x 80) + (1 x 70) / 2 = 75°
The example shows that the weight selected would prioritize
the overall averaged temperature between the two sensors.
The high weight selection caused the remote sensor to have
a higher influence in the calculated temperature average than
the local sensor and the low weight selection caused the
remote sensor to have less influence.

The user selectable temperature is called the dual fuel temperature setpoint, dF and is set in the Installer/Configuration
menu, items 33 or 34. With outdoor remote sensor installed
and enabled, the dual fuel temperature setpoint (menu item
33) can be set to a temperature of -5° through 50°. When
outdoor remote sensor is not installed, a software logic
based dual fuel number (menu item 34) from 01 to 09 can be
selected. A higher temperature or dual fuel setting will provide
a smaller stage separation between the heat pump and Aux
to give more comfort. A lower temperature or number will
provide a larger stage separation for more economy.
is
After the dual fuel temperature setpoint is set and
pressed, a delay, Cd, can be set for compressor shutdown
after the auxiliary stage is energized. This delay can be set
from 0 seconds to 99 seconds to minimize the time that the
system may blow cooler air until the alternate source of heat
comes on. Default setting for delay is 60. When setting the
or
keys are held depressed, the setpoint
delay, if the
will increase or decrease at the rate of one degree every half
second for the first three seconds and double the speed after
three seconds.

Blower Balance Point for Heating
Requires DHM connection from thermostat to heat pump
system. Air to air heat pumps use a fast fan speed to circulate warm air for first stage heating. As outdoor temperatures
drop, the heat pump produces less heat and a high fan speed
makes the air from the ducts feel cooler. Blower Balance Point
allows you to select an outdoor temperature to slow the fan
speed so the air from the duct feels warmer. Select an outdoor temperature where the air from the ducts starts to feel
cool (Installer Configuration Menu item 37). When the outdoor
temperature drops to the selected temperature, the thermostat will slow the fan speed so the outlet air feels warmer.

TROUBLESHOOTING
Comfort Alert Codes
The Comfort Alert diagnostics product monitors the air conditioning outdoor systems with single phase Copeland Scroll
compressors. Abnormal system and electrical conditions are
indicated by flashing ALERT codes on the yellow LED on the
Comfort Alert module. The flash codes are transmitted to the
thermostat by the Comfort Alert Thermostat interface module.
The Comfort Alert compatible thermostat displays “Call For
Service” that flashes at the same rate as the yellow LED on
the Comfort Alert module.

TROUBLESHOOTING
Reset Operation
Note: If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation, you can reset the
thermostat by removing the thermostat from the wall plate and removing batteries for 2 minutes. After two minutes, replace
the batteries and replace thermostat on wall plate. If the thermostat has been reset and still does not function correctly contact
your heating/cooling service person or place of purchase.
Symptom

Possible Cause

Corrective Action

No Heat/No Cool/No Fan
(common problems)

1.	Blown fuse or tripped circuit breaker.
2.	Furnace power switch to OFF.
3.	Furnace blower compartment door or
	 panel loose or not properly installed.
4.	Loose connection to thermostat or system.
1.	Pilot light not lit.
2.	Furnace Lock-Out Condition. Heat
	 may also be intermittent.

Replace fuse or reset breaker.
Turn switch to ON.
Replace door panel in proper position to engage safety
interlock or door switch.
Tighten connections.
Re-light pilot.
Many furnaces have safety devices that shut down when
a lock-out condition occurs. If the heat works intermittently
contact the furnace manufacturer or local HVAC service
person for assistance.
Diagnostic: Set SYSTEM Switch to HEAT and raise the
setpoint above room temperature. Within a few seconds
the thermostat should make a soft click sound. This sound
usually indicates the thermostat is operating properly. If
the thermostat does not click, try the reset operation listed
above. If the thermostat does not click after being reset
contact your heating and cooling service person or place
of purchase for a replacement. If the thermostat clicks,
contact the furnace manufacturer or a HVAC service
person to verify the heating is operating correctly.
Same as diagnostic for No Heat condition except set the
thermostat to COOL and lower the setpoint below the
room temperature. There may be up to a five minute delay
before the thermostat clicks in Cooling.
Check each wire connection to verify they are not shorted
or touching together. No bare wire should stick out from
under terminal block. Try resetting the thermostat as described above. If the condition persists the manufacturer
of your system or service person can instruct you on how
to test the Heat/Cool system for correct operation. If the
system operates correctly, replace the thermostat.
The thermometer can be adjusted +/- 4 degrees. See
Temperature Display Adjustment in the Configuration
Menu section.
Digital thermostats provide precise control and cycle
faster than older mechanical models. The system turns
on and off more frequently but runs for a shorter time
so there is no increase in energy use. If you would like
an increased cycle time, choose SL for slow cycle in the
Configuration menu, step 7 (heat) or 8 (cool). If an acceptable cycle rate is not achieved, contact a local HVAC
service person for additional suggestions.
