SPECIFICATIONS

Models: See Table 1.

Dimensions: See Fig. 1.

Temperature Ratings:

Operating: 45°F to 99°F (7°C to 37°C).

Shipping: -40°F to 150°F (-40°C to 65°C).

Long-term temperature sensor drift:

(for 20K ohm sensors only) 

Maximum sensor drift is nom/-0.13°F after 5 years of 

operation, no appreciable drift thereafter. No calibration of the 

device is possible. Long term drift calibration/maintenance 

through controller software is typically not necessary.

Humidity Ratings: 5 to 95% rh, non-condensing.

Approvals:

National Electrical Code (NEC) Class II.

INSTALLATION

When Installing this Product...

1. Read these instructions carefully. Failure to follow them 

could damage the product or cause a hazardous

condition.

2. Check the ratings given in the instructions and on the 

product to make sure the product is suitable for your 

application.

3. Installer must be a trained, experienced service 

technician.

4. After installation is complete, check out product 

operation as provided in these instructions.

5. Follow local codes for installation and application.

IMPORTANT

All wiring must agree with applicable codes, 

ordinances and regulations.

CAUTION

Electrical Shock or Equipment Damage Hazard.

Can shock individuals or short equipment 

circuitry.

Disconnect all power supplies before installation.

Location

The C7772 Wallplate Temperature Sensor should be located 

where it can sample an average air temperature. Avoid 

locations where air stratification can cause sensing errors. 

The sensor mounts directly on a 2 in. x 4 in. conduit box with 

the screws provided.
