JADE™ Economizer Module

(MODEL W7220)

INSTALLATION INSTRUCTIONS

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 (CO2) 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

When Installing This Product

1.Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition.

2.Check ratings given in instructions and on the product to ensure the product is suitable for your application.

3.Installer must be a trained, experienced service technician.

4.After installation is complete, check out product operation as provided in these instructions.

JADE™ ECONOMIZER MODULE

INSTALLATION AND SETUP

The Economizer module may be mounted in any orientation. However, mounting in the orientation shown above permits proper viewing of the LCD display and use of the keypad.

NOTE: Jade will be in the "set up" mode for the first 60 minutes after powered. If a sensor for OA air or Sylkbus device (sensor, actuator) is disconnected during the set up mode, the Jade will not alarm that failure. The MA sensor is a system "critical" sensor; if the MA sensor is removed during the set up mode, the Jade will alarm. After 60 minutes the Jade controller will change to operation mode and all components removed or failed will alarm in the operation mode.

WIRING

All wiring must comply with applicable electrical codes and ordinances, or as specified on installation wiring diagrams. Module wiring in the field is terminated to the four screw terminal blocks located on the left and right sides.

Module wiring at the OEM factory is terminated via the header pin terminals located on the left and right sides. The header terminal pins and the terminal blocks have common terminations for the appropriate input or output. The part number for the OEM female mating connector is 0039973997.

WARNING

Electrical Shock Hazard.

Can cause severe injury, death or property damage.

Disconnect power supply before beginning wiring, or making wiring connections, to prevent electrical shock or equipment damage.

CAUTION

Equipment Damage Hazard.

Electrostatic discharge can short equipment circuitry.

Ensure that you are properly grounded before handling the unit.

Each terminal can accommodate the following gauges of wire:

Single wire – from 18 AWG to 22 AWG solid or stranded

Multiple wires – up to two 22 AWG stranded

For the 24 Vac connections: single wire – from 14 to 18 AWG solid or stranded

For S-BUS wiring, the sensors may be mounted up to 200 ft. (61 m) from the JADE controller. When the length of wire is over 100 feet use twisted pair shielded wire.

NOTE: All wiring is polarity insensitive.

Refer to Fig. 1 through Fig. 6 for common wiring configurations.

Actuator Wiring Options:

1.The JADE economizer controller can only have one (1) communicating actuator connected to it.

2.Up to four (4) non-communicating and (2) 2-position actuators (1 each on EXH1 and AUX1 O)

3.One (1) communicating and up to four (4) non-commu- nicating and (2) 2-position actuators (1 each on EXH1 and AUX1 O)

When using a 2-position actuator on the AUX1 O the AUX1 O must be programmed for Exh2 and the % open is the % open of the outdoor damper when the 2-pos actuator opens.

Connect 24 V to Exh1 and/or AUX1 O and ground to the Jade "C" terminal.
