Honeywell C7650A specifications

•Senses temperature of outdoor air.

• Long lasting thermistor sensing element is accurate

and stable over time.

•When temperature of outdoor air increases, the

outdoor air damper is closed to a preset minimum

position.

•When temperature of outdoor air is low, the outdoor

air damper is opened to reduce the cooling load in the

building.

•Provides 10 to 20 mA output signal to W7459 Solid

State Economizer Control; setpoint is located on solid

state economizer control.

•Sensor is enclosed in a rugged, corrosion-resistant

glass-fiber reinforced plastic case.

•Compact size and lightweight construction provide

easy mounting in HVAC rooftop unit.

C7650A Solid State Thermistor Sensor is used with the

W7459 Solid State Economizer Control Package. The W7459

Solid State Economizer Control Package is usually mounted

on an M7405/M7415 Actuator. It permits the use of outdoor

air as the first stage of cooling in heating, ventilating and air

conditioning (HVAC) systems. The application is for

differential or single temperature economizer control on

HVAC equipment up to approximately 20 tons.
