WIRING APPLICATION EXAMPLES
This section shows the wiring configurations for the JADE™ Economizer system.
Stand-alone Economizer
The most basic configuration is the stand-alone Economizer (see Fig. 10 and Fig. 15).
A stand-alone Economizer is directly wired to sensors, actuators, thermostat, and mechanical cooling controls in the roof
top unit. It does not require Sylk Bus communications.
