and regulations.
5. Do not route temperature sensor wiring:
a. With building power wiring.
b. Next to control conductors.
c. Near electric motors.
d. Near welding equipment.
e. Near ballast of gas-bulb lighting power transformer.
6. Improper shield grounding or bad connectors can
cause erratic readings.
Install and wire 198212CA Outdoor Temperature Sen-
sors as follows:
1. Mark the area on the wall where the sensor or sun
shield will be mounted.
2. Wire the sensor as shown on the job drawings and
Fig. 35.
