“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

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.

Lk” and “OFF” (default, keypad not locked out). The  
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.  
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.

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.

5) 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. 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.

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.  
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.

IMPORTANT!  
delay second stage for a longer time if you manually raise  
the temperature or if the room temperature quickly changes.  
Once the second stage comes on, it will come on sooner the  
next time there is a difference between the setpoint and the  
room temperature. The net effect of the staging program is  
that when the first stage is capable of making temperature  
the second stage will delay longer. When the thermostat  
calculates that first stage cannot make temperature in a  
reasonable time, the second stage will come on sooner. This  
built in function automatically optimizes the use of additional  
stages of heat or cool.  
Second Stage Time Delay  
Your thermostat is designed to determine the optimum time  
to activate the second stage. Simply raising the temperature  
in heating or lowering it in cooling will not always force the  
thermostat to bring the second stage on quickly. There is a  
time delay from 0-30 minutes depending on the performance  
of the first stage of the system.  
EXAMPLE: For the last 2 hours the thermostat is set on 70°  
and the room temperature is 70° with the equipment using  
only the first stage of heat. Since the equipment is keeping  
the temperature within 1° of setpoint, the thermostat will

PROGRAMMING  
PlanningYour Program – Important  
The Heating and Cooling Program schedules below allow you  
to pencil in your own program times and temperatures.  
The 1F85-0422 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.

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

Symptom  
Possible Cause  
Correction 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.  
Replace fuse or reset breaker.  
Turn switch to ON.  
Replace door panel in proper position to engage safety  
interlock or door switch.  
Tighten connections.  
No Heat  
1. Pilot light not lit.  
Re-light pilot.  
2. Furnace Lock-Out Condition. Heat  
may also be intermittent.  
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  
thermostat requires replacement.  
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.

1. Thermostat thermometer setting  
requires adjustment.  
The thermometer can be adjusted +/- 4 degrees. See  
Temperature Display Adjustment in the Configuration Menu  
section.  
Furnace (Air Conditioner)  
Cycles Too Fast or Too  
Slow (narrow or wide  
temperature swing)  
1. The location of the thermostat and/or  
the size of the Heating System may  
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,  
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.
