For applications where the wire run is short (100 ft.
or less) shielded cable may not be required provided
the wires are not routed parallel to or across other
wires carrying electrical power. To reduce electrical
interference or inductance from other electrical wir­ing or devices use shielded cable and keep Remote
Sensor wire runs separate from thermostat wiring.
Remote sensors cannot be used with systems where
power interruptions are part of normal system op­eration. Compatible with all White-Rodgers remote
sensing thermostats.

To prevent electrical shock and/or equipment
damage, disconnect electric power to system
at main fuse or circuit breaker box until instal­lation is complete.

WARNING

Do not use on circuits exceeding specied

voltage. Higher voltage will damage control

and could cause shock or re hazard.

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.

INDOOR SENSOR

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 . above the room oor
level.

3. Install sensor on a partitioning wall, not on an
outside wall.

4. Never expose sensor to direct light from lamps,

sun, replaces 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.

OUTDOOR SENSOR

SELECT SENSOR LOCATION

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
maximum of 300 feet from the thermostat.

2. Install the interior mounting base within 12 .
of the intended outdoor probe location.

3. Never install the outdoor probe where it will be
exposed to direct light from lamps, sun, re­places 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

aect sensed temperature. Install probe with

spacer to obtain a more accurate temperature.

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 gure 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) eects 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 dierent 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 dierent 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 Test Comments

1. Loss of 24-volt
power.

2. A broken wire on
S1, S2 and S3 or
(+, SA, -) from the
thermostat to the
remote.

3. A shorted or
damaged remote
sensor.

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.

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.

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.

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

uorescent light ballasts that may

cause an inductance to be transmitted
to the thermostat.

Replace 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 recongure
the installer menu for a remote sensor because the reset function may cancel remote sensing.
