Honeywell W7220 Installation Guide

JADE™ Economizer Module

(MODEL W7220)

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.

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

DCV (CO

) 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

JADE™ ECONOMIZER MODULE

WARNING

CAUTION

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.

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.

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-communicating 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.

Note the W7220 economizer will not work with an old “black motor” M7415; replace the M7415 with a M7215 or MS3103 DCA.

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. 7 for common wiring configurations. Refer to Fig. 8 for use with the Smart VFD. Figure 8 shows how to make a single-speed blower operate with two speeds with JADE. When the thermostat calls for first stage cooling or independent fan, the VFD will operate the fan at low speed. When the thermostat calls for first stage heat or second stage cooling, it will operate the fan at high speed. To achieve this, wire relays as shown, and configure the VFD to the minimum frequency M3.3.1 for low speed fan, and for high speed fan configure Preset frequency 1, M3.3.12.
