INSTALLATION  
Battery Location  
WARNING  
Thermostat installation and all components of the  
control system shall conform to Class II circuits per  
the NEC code.  
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)  
!
Remove Old Thermostat  
A standard heat/cool thermostat consists of three basic parts:  
Figure 1 – Thermostat Base Multi-Stage 1F97-1277

2
The cover, which may be either a snap-on or hinge type  
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.

Pull the thermostat body off the thermostat base Forcing  
or prying on the thermostat will cause damage to the unit  
Place base over hole in wall and mark mounting hole  
locations on wall using base as a template  
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

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  
Connect wires to terminal block on base using appropriate  
wiring schematic (see diagrams on next page)  
. Push excess wire into wall and plug hole with a fire resis-  
tant material (such as fiberglass insulation) to prevent  
drafts from affecting thermostat operation

System Switch Configuration (SS1/HP1) – This ther-  
mostat is configured for Heat and Cool with Auto change-  
over default (Cool-Off-Heat-Auto). 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), the  
system switch configuration will have an additional mode  
available namely, Emer for Emergency Mode  
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: Let us say, 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  
On Use  
or  
touch keys to select the feature, OFF  
17 & 18)Select Automatic Schedule – 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 in-  
dicates that the feature is not ready to be used or a  
“Comfort Temperature is already set See Auto Schedule  
in Programming section  
6)  
19) Select Cool Savings™: With Cool Savings™ enabled,  
the thermostat will make small adjustments to the  
setpoint temperature during periods of high demand to  
reduce AC system running time and save energy When  
the cooling system has been running for more than 20  
minutes, humidity in the home will be lower and a higher  
temperature will feel comfortable After 20 minutes of run  
time, the thermostat will start increasing the setpoint  
temperature in steps of less than one degree as the  
system continues to run These adjustments will eventu-  
ally cause the system to satisfy the thermostat to turn the  
system off and reduce the energy consumption When  
the Cool Savings™ feature is active and making ad-  
justments, the display will flash “Cool Savings” The  
amount of the adjustments to the setpoint temperature

Planning Your Program – Important  
The Heating and Cooling Program schedules below allow you to pencil in your own program times and temperatures  
The 1F97-1277 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 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.

Wired Remote Temperature Sensing  
Weight of Remote Reading:  
When in view schedule mode the weight of the indoor remote  
sensor will be shown in the left actual temperature digits des-  
ignated as A2 (default for average weight), H4 (high weight)  
or L1 (low weight) The period (Morning, Day, Evening, Night)  
will also be shown to the right of the weight value in the actual  
temperature digits  
One remote temperature sensor can be installed indoor or  
outdoor and connected to the thermostat by a maximum  
cable length of 100 meters (300 ft) Three terminals, +, S & -  
are provided on the terminal block to connect to the White-  
Rodgers standard wired remote sensor This sensor will be  
read by the thermostat only when 24VAC is present  
When used as indoor sensor, the readings can be weighted  
with the local sensor for specific program periods. User can  
enable or disable the remote sensor in the installer configura-  
tion mode and also the outdoor temperature can be selected  
to show on the display  
When in view schedule mode, press

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
