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 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

for differential enthalpy changeover.

DCV (CO

2

) Sensor (C7232): 2-10 Vdc control signal;

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
