INSTALLATION INSTRUCTIONS62-0331-15 jade Economizer Module (MODEL W7220)This document describes wiring, power up, basic troubleshooting, and common installation issues for the jade Economizer Module (Model W7220). For further information on mounting and operation, refer to Honeywell document INSTALLATIONR eview the following before installing the The W7220:ElectricalRated Voltage: 20 to 30 Vac RMS; 50/60 HzTransformer: 100 VA maximum system inputRelay Digital Output Rating: 30 Vac IMPORTANTAll inputs and outputs must be Class 2 wiring. InputsA Mixed air (MA) analog sensor is required on all W7220 units; either an OA (Outdoor Air) sensor for dry bulb change over or an OA Sylkbus sensor for outdoor enthalpy change over is required in addition to the MA sensor . An additional Return Air (RA) Sylkbus sensor can be added to the system for differential enthalpy changeover.
