WARNING  
Thermostat installation and all components of the  
control system shall conform to Class II circuits per  
the NEC code.  
“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.  
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 approxi-  
mately 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 recom-  
mend 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  
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.  
or  
. Another offset will occur within two days if batter-  
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 snug-  
ly, 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 re-  
sistant 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.

1) This control can be configured for:  
8) Select Compressor Lockout CL OFF or ON – Select-  
ing 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 com-  
pressors 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 oc-  
curs, it will flash the setpoint for up to five minutes.  
9) 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).  
10) Select Backlight Display – The display backlight im-  
proves 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.

SS 1 – Single Stage System  
2) GAS or Electric (ELE) fan operation. If the heating sys-  
tem requires the thermostat to energize the fan, select  
ELE. Select GAS if the heating system energizes the fan  
on a call for heat.  
3) 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. Selecting a value  
greater than 0 will display Cool Savings on the screen  
and enable the key for Cool Savings feature. Cool Sav-  
ings 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. Adjust-  
ing 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 ad-  
justments to the room temperature display “Save” will be  
flashing and the displayed room temperature may vary  
within the adjustment range you selected.  
11) 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 cali-  
brated at the factory, but you have the option to change  
the display temperature to match your previous thermo-  
stat. The current or adjusted room temperature will be  
displayed.  
12) Select F° or C° Readout – Changes the display readout  
to Celsius or Fahrenheit as required.  
13 & 14) Temperature Limit Range Heat or Cool – This  
selection sets the maximum HEAT (13) or minimum  
COOL (14) temperature for the setpoint range. Select the  
limit temperature using the  
or  
keys. In the Run  
Schedule mode, the setpoint temperature will not adjust  
past the limit temperature selected. When the limit tem-  
perature is reached, trying to raise or lower the setpoint  
past the limit will cause “Lto be displayed in the times  
digits for about 6 seconds. This feature not available on  
earlier models.  
If “Save” is not displayed and this feature is OFF, no  
change will occur when the cooling system is continu-  
ously running during periods of high demand.  
4) Energy Management Recovery: (this step is skipped if  
configured to be non-programmable). Energy Manage-  
ment 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. Heat-  
ing will start 5 minutes early for every 1° of temperature  
required to reach setpoint.  
15) Program Options: Not available on 1F83, configured for  
5/1/1 day or 5/2 day programming or non-programma-  
ble 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.  
16 & 17) Select Automatic Schedule – Not available on  
1F83, with just one touch of the Auto Schedule button  
this feature allows you to program a desired comfort tem-  
perature 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.  
Example: E On is selected and your heating is pro-  
grammed to 65° at night and 70° at 7 AM. If the build-  
ing 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.  
5, 6 & 7) Cycle Rate Selection – The factory default setting  
for Heat and Cool modes, SS1, MS2, is medium cycle  
(ME). For Heat Pump, HP1, HP2, the default setting is  
medium (ME). For Emer (Aux) the default setting is fast  
cycle (FA). To change cycle rate, press the  
key.  
or

20) 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 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.  
23) 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.

PlanningYour Program – Important  
The Heating and Cooling Program schedules below allow you  
to pencil in your own program times and temperatures.  
The programmable comes configured for 5/1/1 day program-  
ming and can also be configured for 5/2 day programming  
(see configuration section).  
If you are re-programming a 5+1+1 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 higher than the cooling.  
Factory settings are listed on Monday through Friday, Satur-  
day and Sunday. If you are re-programming a 5/2 day sched-  
ule, pencil in your own times and temperatures directly below  
the factory times and temperatures.

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.  
3. Heating system requires service or  
thermostat requires replacement.  
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.  
No Cool  
1. Cooling system requires service or

be influencing the cycle rate.  
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,
