INSTALLATION INSTRUCTIONS

DESCRIPTION

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 F145-1328 remote sensor is approved for indoor use
only.

Temperature range: 40° to 99° F.

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 200 feet
from the thermostat.

PRECAUTIONS

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 specified voltage.
Higher voltage will damage control and could cause
shock or fire 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.

SPECIFICATIONS

Operating humidity range: 0 to 90% RH (non-condensing).

20 gauge, three-conductor shielded cable must be used for all
remote sensor wiring.

INSTALLATION

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.

INSTALLATION (cont’d)

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 senosr 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.

WIRING REMOTE SENSOR

Installation of the remote sensor requires 20 gauge, three­conductor thermostat wire. The thermostat and remote sensor
must be wired so that terminals “+”, “S”, and “–” on the sensor
match up correctly with “+”, “S”, and “–” or “S1”, “S2”, and “S3”
on the thermostat.

See figs. 1, 2, and 3 for correct wiring between thermostat and
remote sensor(s).

CAUTION

!

Do not allow the 3-conductor wire to be pinched
between the sensor and the wall.

Check wire connections before applying power. Im­proper connections will lead to permanent damage to
the sensor.

20 Gauge Shielded cable must be used. Cable shield
must be connected to "-" or S3 on the THERMOSTAT
ONLY (see figs. 2 and 3).
