INSTALLATION
INDOOR SENSOR
1. The interior mounting base can be located a
maximum of 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.
SELECT SENSOR LOCATION
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 maximum
of 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.
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.

6. Although connected to the probe wire for outdoor temperature 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
Consult Maximum Sensing Locations Per Thermostat chart on page 6 to determine how many sensors a
thermostat will accept.
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.

TROUBLESHOOTING
To function correctly and read temperature accurately, the thermostat 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.
Condition
1. Loss of 24-volt
power.
Test
On models with batteries, remove
the batteries and re-install thermostat. If the display is blank,
check heating and cooling system
to determine why 24-volt power is
absent.
2. A broken wire on
S1, S2 and S3 or
(+, SA, -) from the
thermostat to the
remote.
Disconnect sensor wires at thermostat. Attach a short piece (2')
of three-wire shielded cable to
S1, S2 and S3 or (+, SA, -) on the
subbase. Bring the remote sensor
to the thermostat location and
attach S1, S2 and S3 or (+, S, -)
respectively. Reattach thermostat.
If the temperature begins to climb
(slowly), it is reading correctly. If it
reads correctly with the 2' length
but improperly when attached to
the wire run, it indicates a fault in
the wire run.
Replace remote sensor.
Because it is an electronic sensor,
there are no Ohm values to test. If
correct conditions as listed in 1 & 2
above and the temperature stays at
or near 08°, it indicates a shorted or
damaged remote sensor.
3. A shorted or
damaged remote
sensor.
Comments
For the sensor to read correctly, the
24-volt system power must be present.
Some systems may require an isolation
relay to provide constant power to the
thermostat. Limit or safety devices in
the equipment can also cause a power
interruption.
Repair or replace the 3 wire shielded
cable. Be sure the remote wire run is
not parallel to line voltage wires that
carry heavy inductive loads, or across
fluorescent light ballasts that may
cause an inductance to be transmitted
to the thermostat.
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.
