INSTALLATION
!
WARNING
Thermostat installation and all components of the control system shall conform to Class II circuits per the NEC code.
Figure 1 – Battery door shown open
“AA” Alkaline Batteries
Remove Old Thermostat
A standard heat/cool thermostat consists of three basic parts:
1) The cover, which may be either a snap-on or hinge type.
2) The base, which is removed by loosening all captive screws.
3) The switching subbase, which is removed by unscrewing the mounting screws that hold it on the wall or adapter plate.
Before removing wires from old thermostat,
label each wire with the terminal designation from
which it was attached. Disconnect the wires from the old thermostat one at a time.
Do not let wires fall back into the wall.
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 2 and two mounting screws. Leveling is for appearance only and will not affect thermostat operation.
5) Connect wires to terminal block on base.
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.
7) Carefully line the thermostat up with the base and snap into place.
Batteries
2 “AA” alkaline batteries are included with the thermostat.
To install the batteries, pull the battery door as shown by the arrow and lift open. Using the polarity indicated inside the battery door, insert the batteries. To close the battery door, swing the door down while pulling in the direction of arrow. Once fully down, snap the door back into position. To replace the batteries, set system to OFF.
Thermostat can be powered by system AC power or Battery.
If is displayed, the thermostat is battery powered. If is not displayed, thermostat is system powered with optional battery back-up. When battery power remaining is approximately half, the will be displayed. When
“Change ”
is displayed, install fresh “AA” alkaline batteries immediately.
For best results, replace all batteries with new premium brand alkaline batteries such as Duracell
®
or Energizer
®
. We recommend replacing batteries every 2 years. 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. When less than two months of battery life remain, the setpoint temperature will offset by 10 degrees (10 degrees cooler in Heat mode / 10 degrees warmer in Cool mode). If offset occurs, the normal setpoint can be manually reset with or . Another offset will occur within two days if batteries are not replaced.

INSTALLER/CONFIGURATION MENU
1)
Keypad Lockout – This menu selection will display “Lk” and “OFF” (default, keypad not locked out). The and
are used to toggle the selection between OFF and
“
L” (keypad locked out). When the keypad lockout selection is enabled “L”, and the MENU button is pressed again, the display will indicate the number “0” (default, still disabled) in the time digits. The and are used to set the combination number from
0 to 999. If a combination of 0 is selected and the MENU button is pressed, the menu will be exited and keypad will not be locked. If
1 to 999 is selected and the MENU button is pressed, the combination is stored into memory and the menu is exited. The “ LOC” will display designating keypad locked with a valid combination. The SYSTEM button will operate for 10 seconds after the menu mode is exited to allow the user to change the mode from “ OFF” to the desired SYSTEM mode.
While the keypad is locked out, a press of MENU will enter the configuration menu. The first menu item displayed is the combination code “ 0”. The or keys are used to set the combination unlock number from
0 to
999. If the unlock number matches exactly with the combination lock number stored in memory when the MENU button is pressed, the keypad is unlocked and the “LOC” is removed. If the unlock number does not match when the MENU button is pressed, the combination returns to
“0” for another attempt to set the unlock code. To exit the menu without unlocking the keypad, press RUN SCHED.
To reset the combination code and unlock the keypad if the code is forgotten, see troubleshooting section.
2) This control can be configured for:
MS 2 – Multi-Stage System (no heat pump)
HP 1 – Heat Pump with one stage of compressor
SS 1 – Single Stage System
3) 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.
4)
Select Cool Savings™ value – Selects the amount of adjustment for the Cool Savings™ feature in Cool mode with 1 (1°) being the least amount of adjustment and 6 (6°) being the most amount of adjustment. Default value is 0 which disables this feature. Cool Savings is an optional energy saving feature that can reduce your cooling costs. It is based on the principal that lower indoor humidity makes a slightly higher temperature feel more comfortable. Cool Savings operates during periods of high demand which normally occur on the hottest summer days when a cooling system may run for hours to reach the thermostat setting. Long cooling run times also lower the indoor humidity. Cool Savings, very slowly, adjusts the setpoint temperature to make the setpoint closer to the displayed room temperature, to a maximum of the number of degrees you select. Adjusting the setpoint temperature over a long cooling run time allows the system to reach your set temperature and turn off. The room temperature will actually be higher than the thermostat displays but the reduction in humidity will allow comfort at the slightly higher temperature.
To turn this feature on in the Cool mode press
Cool
Savings. The display will show “Save” next to the setpoint temperature. When Cool Savings is making adjustments to the room temperature display
“Save” will be flashing and the displayed room temperature may vary within the adjustment range you selected.
If
“Save” is not displayed and this feature is OFF, no change will occur when the cooling system is continuously running during periods of high demand.
5)
Energy Management Recovery: (this step is skipped if configured to be non-programmable). Energy Management Recovery (E) On enables the thermostat to start heating or cooling early to make the building temperature reach the program setpoint at the time you specify. Heating will start 5 minutes early for every 1° of temperature required to reach setpoint.
Example: E On is selected and your heating is pro- grammed to 65° at night and 70° at 7 AM. If the building temperature is 65°, the difference between 65° and
70° is 5°. Allowing 5 minutes per degree, the thermostat setpoint will change to 70° at 6:35 AM. Cooling allows more time per degree, because it takes longer to reach set temperature.
6, 7 & 8) Cycle Rate Selection – The factory default setting for Heat and Cool modes, SS1 and MS2 is medium cycle
(ME). For Heat Pump and HP1, the default setting is medium (ME). For Emer (Aux) the default setting is fast cycle (FA). To change cycle rate, press the or key.
Cycle rate differentials for different settings are:
MODE
Heat (SS1, MS2)
Cool (SS1, MS2)
Fast
FA
Medium Slow
ME SL
0.4°F 0.6°F 1.7°F

Emer (HP1)
0.9°F 1.2°F 1.7°F
0.9°F 1.2°F 1.7°F
0.6°F - 1.7°F
9) Select Compressor Lockout CL OFF or ON – 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 newer compressors already have a time delay built in and do not require this feature. Your compressor manufacturer can tell you if the lockout feature is already present in their system. When the thermostat compressor time delay occurs, it will flash the setpoint for up to five minutes.
10)
System Mode Configuration – This thermostat is configured for Heat and Cool (SYSTEM switch with Cool Off
Heat) default. It can also be configured for Heat and Cool with Auto changeover (Heat, Auto, Cool, Off), Heat only with fan (Off Heat), Heat only without fan, Auto only
(Auto Off), and Cool only (Cool Off).
11) Select Backlight Display – The display backlight improves display contrast in low lighting conditions. When the “C” terminal is powered, selecting backlight CdL ON will keep the light on continuously. Select backlight OFF will turn the light on momentarily after any key is pressed.
When the “C” terminal is not powered, the light will be on momentarily after any key is pressed no matter whether the backlight is selected ON or OFF.
12)
Select Temperature Display Adjustment 4 LO to 4 HI
– Allows you to adjust the room temperature display up to 4° higher or lower. Your thermostat was accurately calibrated at the factory, but you have the option to change the display temperature to match your previous thermostat. The current or adjusted room temperature will be displayed.
13)
Select F° or C° Readout – Changes the display readout to Celsius or Fahrenheit as required.
14) Limited Heat Range – This feature provides a maximum setpoint temperature for heat. The default setting is 90
°F.
It can be changed between 62°F and 89°F by pressing the or key.
15)
Limited Cool Range – This feature provide a minimum setpoint temperature for cool. The default setting is 45 °F.
It can be changed between 46 °F and 82°F by pressing the or key.
16) Program Options: Configured for 5/1/1 day or 5/2 day programming or non-programming mode. The default setting is P3, indicating 5/1/1 day programming. The programs per week can be changed to P2 or P0 by pressing the or keys. A selection of 0 Days for non-programmable will eliminate the need for EMR, and that step in the menu will be skipped.
5
INSTALLER/CONFIGURATION MENU
17 & 18)
Select Automatic Schedule – With just one touch of the Auto Schedule key this feature allows you to program 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 temperature and press
Auto Schedule. This value will be copied into all the morning, day and evening program periods. The night program periods will have a
6°F set back.
19 & 20) Select Fast Second Stage ON or OFF – Heat pump or Multi-stage only, in the run mode, with the fast
Heat feature enabled (FA Heat On), if the Heat setpoint temperature is manually raised by 3°F (2°C) or more above the actual temperature using the second stage will energize immediately. With FA OFF, second stage will not energize until the setpoint temperature is
1°F or more above actual temperature for more than ten minutes. The Fast Cool feature (FA Cool) provides the same controls when the setpoint temperature is lowered.
21) Comfort Alert with Active Protection – 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 Yellow 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.
22) 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 On. Use or touch keys to select the feature OFF.
23)
Select Filter Replacement Reminder and Set Run
Time – Select the “Change Filter” reminder On or
OFF. If selected On, press MENU to select the time period from 25 to 1975 hours in 25 hours increments.
In a typical system, 200 hours (default) of run time is approximately 30 days. After the selected time of blower operation, the thermostat will display
“Change Filter”
as a reminder to change or clean your air filter. When
“Change Filter” is displayed, press MENU or RUN
SCHED button to clear the display and restart the time to the next filter change.
24)
Select Reversing Valve Output – The O/B option is factory set at “O” position. This will accommodate the majority of heat pump applications, which require the changeover relay to be energized in
COOL. If the thermostat you are replacing or the heat pump being installed with this thermostat requires a “B” terminal, to energize the changeover relay in
HEAT, the O/B option should be set at “B” position.

TROUBLESHOOTING
Reset Operation
Note: When thermostat is reset, installer configuration menu settings and programming will reset to factory settings.
If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation, you can reset the thermostat by removing the wires from terminals R and C
(do not short them together) and removing batteries for 2 minutes. After resetting the thermostat, replace the wires and batteries. If the thermostat has been reset and still does not function correctly contact your heating/cooling service person or place of purchase.
Note: Be sure to review the installer configuration menu settings.
To reset the programming, clock and configuration settings, press and and the FAN button simultaneously. The thermostat should go blank and then all segments will be displayed momentarily.

Possible Cause
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.
3. Heating system requires service or
thermostat requires replacement.
1. Cooling system requires service or
thermostat requires replacement.
1. Possible short in wiring.
2. Possible short in thermostat.
3. Possible short in heat/cool/fan system.
4. FAN Switch set to Fan
ON.
1. Thermostat thermometer setting
requires adjustment.
1. The location of the thermostat and/or
the size of the Heating System may
be influencing the cycle rate.
Correction Action
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 6 (heat), 7 (cool) or 8 (heat pump). If an acceptable cycle rate is not achieved, contact a local HVAC service person for additional suggestions.
Hold MENU key for 20 seconds and the lockout will reset.
