250 F 121 C Electronic Temperature Sensor W973 and M7415; W7210, W7212, W7213,

C7150 Solid State mixed air sensor is used with Honeywell
economizer logic modules and W973 and M7415 to proportion
outdoor and return air dampers in economizer systems.

• Uses thermistor sensing element in ventilation duct systems

• Negative temperature coefficient (NTC) causes resistance
to decrease as sampled air temperature increases

• Resistance change used as in input to control W973 and M7415

• Requires no settings or calibration

• Mounts on duct surface with four screws (not supplied)

Mounting: Mount on a mounting bracket (not included) inside the mixed

air or discharge air duct

Operating Temperature Range: 40 F to 110 F (4 C to 43 C)
Electrical Connections: 1/4 in. (6 mm) quick-connect terminals

C7250 Temperature Sensor

The C7250 Mixed Air sensor is designed for use as a 20k input to a
controller for mixed air temperature in rooftop packaged air
conditioning equipment.

A separate controller such as the JADE™ Economizer System
(Model W7220) provides power and communications for the C7250
Mixed Air sensor.

Application: Electronic 20K temperature sensor
Dimensions, Approximate: 4.25 in high x 2.17 in wide x .81 in deep

(108 mm high by 55 mm wide x 20.5 mm deep)

Sensor Type: 20K NTC
Color: Gray
Mounting: Mounted in any position where it is exposed to freely circulating air
Operating Temperature Range: -40 F to 150 F (-40 C to 66 C)
