Honeywell C7400S Installation Instructions

C7400S Enthalpy Sylk Bus Sensor

PRODUCT DESCRIPTION

The C7400S Sylk Bus sensor is a combination temperature
and humidity sensor, which is intended to be used in
commercial roof top units for sensing air. The sensor is
powered by and communicates on the Sylk Bus. The C7400S
communicates temperature and humidity separately digitally
on the Sylk Bus Communication Protocol.
A separate controller such as the JADE™ Economizer
System (Model W7220) provides power and communications
on the Sylk Bus for the C7400S Sylk Bus sensor.
