Locate and Mount C7189U Remote Indoor

Temperature Sensor (Optional)

1. Choose a location (see Fig. 27) for mounting the sensor

on an inside wall about 5 ft (1.5m) above the floor. A

vertically-mounted standard 2 x 4 in. (51 x 102 mm)

junction box can also be used.

2. Be sure wire distance between C7189 and thermostat is

less than 200 feet.

3. Make sure there is good air circulation at average

temperature at the chosen location. Avoid the following

locations because they can introduce errors in sensor

measurements. See Fig. 27.

a. Hot areas caused by:

(a) Concealed pipes or ducts.

(b) Drafts from fireplaces or other heat sources.

electrical equipment.

b. Cold areas caused by:

(a) Concealed pipes or ducts.

(b) Drafts from windows and doors.

location.

c. Dead air areas:

(a) Behind doors, furniture and curtains.

(b) In corners and alcoves.

4. Mark the area on the wall selected for mounting the

C7189 Sensor or junction box.

5. Run wire cable to a hole at the selected wall location.

Pull approximately three inches of wire through the

opening. Color-coded, 18-gauge thermostat wire is

recommended.

Wire C7189 Indoor Sensor

CAUTION

Electrical Interference (Noise) Hazard.

Can cause erratic system operation.

Keep wiring at least one foot away from large inductive

loads such as motors, line starters, lighting ballasts

and large power distribution panels.

IMPORTANT

Erratic temperature readings from a sensor can

occur as a result of any of the wiring practices

described below. Avoid these practices to assure

correct operation.

— Be sure wires have a cable separate from the

thermostat cable.

— Do not route temperature sensor wiring with building

power wiring, next to control contactors or near light

dimming circuits, electric motors or welding

equipment.

— Avoid poor wiring connections.

— Avoid intermittent or missing building earth ground.

CAUTION

Electrical Shock Hazard.

Can cause electrical shock or equipment damage.

Disconnect power supply before connecting wiring.

Wiring must comply with applicable codes, ordinances and

regulations.

1. Wire C7189 Indoor Sensor to S1and S2 terminals on

the thermostat. For an example of general wiring of

C7189, see Fig. 28 to wire one sensor and 29 to wire

multiple sensors.

2. Push excess wire back into the hole. Plug the hole

using nonhardening caulk, putty or insulation to prevent

drafts from affecting performance.

3. Remove C7189 cover.

4. Mount C7189 to the wall or junction box using the

screws and anchors provided.

5. Level the C7189 for appearance only. Device functions

correctly even when not level.

6. Install C7189 cover.
