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 63-2700.

BEFORE INSTALLATION

Review the following before installing the The W7220:
Electrical
Rated Voltage: 20 to 30 Vac RMS; 50/60 Hz
Transformer: 100 VA maximum system input
Relay Digital Output Rating: 30 Vac
IMPORTANT
All inputs and outputs must be Class 2 wiring.
Inputs
A 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
INSTALLATION INSTRUCTIONS
for differential enthalpy changeover. JADE can be used with a
CO2 indoor air sensor for Demand Control Ventilation and
with a VFD for two speed fan operation.
DCV (CO
) Sensor (C7232): 2-10 Vdc control signal;
2
minimum impedance >50k ohm.
Outputs
Actuator signal: 2-10 Vdc; minimum actuator impedance is
2k ohm; Sylkbus two-wire output for Honeywell Sylkbus
communicating actuators.
Exhaust fan, Y1, Y2 and AUX1 O: Contact closure (24 Vac)
All Relay Outputs (at 30 Vac):
Running: 1.5A maximum
Inrush: 7.5A maximum
