ECONOMIZER MODULE WIRING DETAILS — Use
Fig. 38 and Tables 9 and 10 to locate the wiring terminals for
the Economizer module.
NOTE: The four terminal blocks are removable. Slide out each
terminal block, wire it, and then slide it back into place.
Fig. 38 — W7220 Wiring Terminals
S-Bus Sensor Wiring — The labels on the sensors and con-
troller are color coded for ease of installation. Orange labeled
sensors can only be wired to orange terminals on the controller.
Brown labeled sensors can only be wired to S-bus (brown) ter-
minals. Use Fig. 38 and Table 9 to locate the wiring terminals
for each S-Bus sensor.
Use Fig. 38 and Table 12 to set the DIP switches for the de-
sired use of the sensor.
