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.
All wiring must conform to local and national electrical codes
and ordinances.
This control is a precision instrument, and should be handled
carefully. Rough handling or distorting components could cause
the control to malfunction.
The remote sensors cannot be used with systems where power
interruptions are part of normal system operation.

Proper location insures that the remote sensor will provide a
comfortable home or building temperature. Observe the following general rules when selecting a location:
1. The remote sensor can be located a
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.
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.
6. Avoid locations close to air registers or in the direct path of
air from them.
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.
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.

Proper location insures that the remote sensor will provide a
correct outdoor temperature reading. Observe the following
general rules when selecting a location:
1. The interior mounting base can be located a
300 feet from the thermostat.
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. Make sure there are no pipes or ductwork in the wall
chosen for the base location.
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.

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 calculated 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.

room temperature display use the reset instructions listed in the installation instructions for the thermostat model you are

sure to reconfigure the installer menu for a remote sensor because the reset function may cancel remote sensing.
