WIRING APPLICATION
EXAMPLES
This section describes the wiring configurations for the JADE™
Economizer system. The configurations are:
— “Stand-alone Economizer”
— “Economizer with Sylk Bus Sensors” on page 9
Stand-alone Economizer
The most basic configuration is the stand-alone Economizer
(see Fig. 7 and Fig. 8 on page 8).
A stand-alone Economizer is directly wired to sensors,
actuators, thermostat, and mechanical controls in the roof top
unit. It does not require Sylk Bus communications.
