C7772A, F, G

Wallplate Temperature Sensor

APPLICATION

The C7772A series of Wallplate Temperature Sensors are 

designed to be used with the Excel 5000 family and other 

Honeywell controllers. The C7772F Series is designed to be 

used with the TB7600, TB7300, and TB7200 Series 

communicating thermostats and other controllers that require 

a 10K ohm NTC Type II sensor. The C7772G is designed to 

be used with WEBs-AX I/O modules and other controllers that 

require a 10K ohm NTC Type III sensor. The C7772 sensors 

provide a resistive output signal proportional to sensed room 

or space temperature. The C7772 is well suited for low-profile 

wall-mounted applications where durability and tamper-proof 

construction is desired, such as schools, prisons and 

institutions.

FEATURES

• Low profile when mounted on industry standard utility 

conduit box.

• Rugged, brushed stainless steel wallplate.
• Integral foam pad isolates wallplate sensor from conduit 

box.

• Insulated screw terminals ensure reliable field wiring 

connection.

• Models available with a variety of resistive temperature 

sensor elements.
