C7660

Selectable Temperature Sensor

FOR ECONOMIZERS

PRODUCT DATA

FEATURES

GENERAL

C7660 Selectable Temperature Sensor is used with the W7459, W7215, W7212, W7213 and W7214 Economizer Controls. The economizer controls are mounted on an M7415/ M7215 Actuator. They permit the use of outdoor air as the first stage of cooling in heating, ventilating and air conditioning (HVAC) systems.

The C7660 Selectable Temperature Sensor is only to be used with single temperature change over with the sensor located in the outdoor air.

•Senses temperature of outdoor air and provides a signal to economizer control with OK or not OK to economize.

•Selectable dip switch provides 8 change over temperature options.

•When temperature of outdoor air is below change over temperature, the outdoor air damper is opened to reduce the cooling load in the building.

•Provides 4 OR 20 mA output signal to economizer control; At 4 mA not OK to economize, 20 mA OK to economize.

•Highly accurate microprocessor control.

•Sensor is enclosed in a rugged, corrosion-resistant plastic case.

•Replaces C7650 temperature sensors and the control function of temperature change over in the economizer control.
