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 116
Stand-alone Economizer
The most basic configuration is the stand-
alone Economizer (see Fig. 4 and Fig. 6). 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.
