INSTALLATION
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. Makesure there are no pipes orductworkinthat
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. Inthehome,thelivingor diningroomisnormally
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.

Spacer
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 1.

Checkwireconnectionsbeforeapplyingpower.
Improper connections will lead to permanent
damage to the sensor.
When shielded cable is used, cable shield must

To function correctly and read temperature accurately, the thermostat must have constant 24-volt pow-
er. 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.
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.
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.
2. A broken wire on
+, S or - from the
thermostat to the
remote.
Disconnect sensor wires at
thermostat. Attach a short piece
(2') of three-wire shielded cable to
+, S, and - on the subbase. Bring the
remote sensor to the thermostat
location and attach +, S, and -,
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.
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.
3. A shorted or
damaged 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.
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.
