PRECAUTIONS  
CAUTION  
To prevent electrical shock and/or equipment dam-  
age, disconnect electric power to system at main fuse  
or circuit breaker box until installation is complete.  
!
NOTE  
If in doubt about whether your wiring is millivolt, line, or low  
voltage, have it inspected by a qualified heating and air  
conditioning contractor or electrician.  
Do not exceed the specification ratings.  
WARNING  
Do not use on circuits exceeding specified voltage.  
Higher voltage will damage control and could cause  
shock or fire hazard.  
!
All wiring must conform to local and national electrical codes  
and ordinances.  
This control is a precision instrument, and should be handled  
carefully. Roughhandlingordistortingcomponentscouldcause  
the control to malfunction.  
Do not short out terminals on gas valve or primary  
control to test. Short or incorrect wiring will damage  
thermostat and could cause personal injury and/or  
property damage.  
The remote sensors cannot be used with systems where power  
interruptions are part of normal system operation.

300 feet from the thermostat.  
2. Locate sensor about 5 ft. above the room floor level.  
3. Install sensor on a partitioning wall, not on an outside wall.  
2. Install the interior mounting base within 12 ft. of the  
intended outdoor probe location.  
3. Never install the outdoor probe where it will be exposed to  
direct light from lamps, sun, fireplaces or any temperature  
radiating equipment.  
4. Never expose sensor to direct light from lamps, sun,  
fireplaces or any temperature radiating equipment.  
5. Avoid locations close to windows, adjoining outside walls,  
or doors that lead outside.  
4. Make sure there are no pipes or ductwork in the wall  
chosen for the base location.  
6. Avoid locations close to air registers or in the direct path of  
air from them.  
5. Outdoor temperature measurement requires installing the  
probe outdoors. Good probe locations would be under a  
bay window or overhang, out of direct sunlight. Direct sun  
exposure will affect sensed temperature. Install probe with  
spacer to obtain a more accurate temperature.  
7. Make sure there are no pipes or duct work in that part of  
the wall chosen for the sensor location.  
8. Never locate sensor in a room that is normally warmer or  
cooler than the rest of the home (such as the kitchen) or  
building.  
9. Avoid locations with poor air circulation, such as behind  
doors or in alcoves.  
Mounting  
10. In the home, the living or dining room is normally a good  
location, provided there is no cooking range or refrigerator  
on opposite side of wall.

6. Although connected to the probe wire for outdoor tempera-  
ture sensing, the interior mounting base must be placed  
indoors. Therefore, the interior mounting base must be  
installed near the perimeter of the building, so that the  
probe wire can be run through to the outside of the  
structure and placed in the selected (shaded) location. The  
outdoor probe wire is 12 feet long (and should not be cut  
or spliced), so plan the placement of both the probe and  
interior mounting base accordingly. Any excess wire may  
be coiled or bundled. The probe should be connected to E2  
as shown in figure 2.

REMOTE SENSOR CALCULATED PRIORITY AVERAGE  
1F93-380, 1F94-371, 1F95-371, 1F95-377, 1F95-391  
Single stage thermostats accept only 1 remote sensor. 90 Series multi-stage and heat pump thermostats accept up to 3  
indoor remote sensors and can be assigned sensor priorities.  
Tables 1-3 show how priority (LO, AVG, HI) effects the room temperature calculation. The example below table three shows  
the calculation of each remote sensor and how it uses them to arrive at room temperature average.

The example below lists three sensors each with a different priority and room temperature. All three sensors are combined in  
the calculation to display the average temperature. The priority multiplier shown in the tables above causes a sensor with  
low priority to carry less weight in the calculated average. A sensor with a HI priority setting contributes more to the calcu-  
lated average. Assume that the building in which the thermostat is located has three indoor remote sensors (SA, SB, SC)  
that have different room temperatures (70, 75, 80). The calculated average will be displayed as the room temperature  
shown in the example below.

Troubleshooting Chart  
To function correctly and read temperature accurately, the thermostat (when set up for a remote as outlined above) must  
have constant 24-volt power. If the thermostat temperature is steadily dropping, reading low, or reads 08° when a remote  
sensor is installed, it can be traced to one of the three following conditions.

Test

temperature stays at or near 08°, it indicates a shorted or  
damaged remote sensor.  
Note: Digital thermostats and remote sensors acclimate very slowly to temperature change. It may take an hour or more for  
the temperature to acclimate to the room temperature from a low temperature reading as outlined above. To expedite the  
room temperature display use the reset instructions listed in the installation instructions for the thermostat model you are  
working with. When reset, the thermostat will default to a room temperature of 70° and begin sensing room temperature. Be  
sure to reconfigure the installer menu for a remote sensor because the reset function may cancel remote sensing.
