C7189U Remote Indoor Sensor
(USE WITH VISIONPRO® THERMOSTATS)
INSTALLATION INSTRUCTIONS
APPLICATION
This indoor sensor is designed to sense temperature at a remote location and send this information to the VisionPRO Thermostat. This sensor can be used as a stand alone sensor or as part of an averaging network. Once a remote indoor temperature sensor is connected to the thermostat, the thermostat's sensor is no longer used. The thermostat's installer setup should be modified to tell the thermostat that remote indoor temperature sensor(s) have been used. The Inside temperature reading on the thermostat's display will be the remote sensor(s) temperature location(s).

Remote Sensor Wallplate Installation
Remove the cover from the remote sensor as shown in Fig. 3.
1.Pull wires through wire hole.
2.Position wallplate on wall, level and mark screw hole positions with pencil.
3.Drill holes at marked positions, then tap in supplied wall anchors.
4.Place wallplate over anchors, insert and tighten mounting screws. See Fig. 4.

C7189U REMOTE INDOOR SENSOR
WIRING
The sensor can be used to provide one remote sensor (see Fig. 6) or as a temperature averaging network with multiple sensors connected (see Fig. 7). The thermostat is not part of the average network.
CAUTION
ELECTRICAL HAZARD.
Can cause electrical shock or equipment damage. Disconnect power before wiring.
1.Run the wire cable from the thermostat to the remote sensor location.
2.Loosen screw terminals, insert wires into terminal block (polarity does not matter), then retighten screws.
3.Push excess wire back into the wall opening.
4.Plug the wall opening with non-flammable insulation to prevent drafts from affecting the sensor operation and replace the cover on the remote sensor.
5.Connect the two wires to the thermostat's remote sensor terminals (polarity does not matter) and replace the thermostat back onto the wallplate. See Fig. 6.

OPERATION
Once a remote indoor temperature sensor is connected to |
. |
the thermostat, the thermostat's sensor is no longer used. |
|
The thermostat's installer setup should be modified to tell |
|
the thermostat that remote indoor temperature sensor(s) |
|
have been used. The Inside temperature reading on the |
|
thermostat's display will be the remote sensor(s) |
|
temperature location(s). See Fig. 8. |

CHECKOUT
For best results, allow the sensor to absorb the air moving through the room for a minimum of twenty minutes before taking a resistance measurement.
1.Use an accurate thermometer (+/-1ºF[0.5ºC]) measure the temperature at the sensor location.
2.Remove one wire from one of the sensor's wiring terminals. Use an ohmmeter to measure the resistance across the sensor. Verify the sensor accuracy with the temperature/resistance in Table 1.
CALIBRATION
The sensor is calibrated at the factory and cannot be recalibrated in the field.
