The JADE™ Economizer System includes an Economizer Module, 20k mixed air sensor, damper actuator, an optional CO

sensor, and either a 20k outdoor air temperature sensor

or Sylk Bus sensors for measuring Outdoor Air and return air enthalpy, temperature, and humidity.

Economizer Module

This is the core of the JADE™ Economizer System and includes the user interface for the system. The W7220 Economizer Module provides the basic inputs and outputs to provide simple economizer control. When used with the optional Sylk Bus sensors, the Economizer Module provides more advanced economizer functionality.

Sylk Bus Sensors (optional)

PRODUCT DESCRIPTION

The JADE™ Economizer System is an expandable economizer control system, which includes a W7220 Economizer Module (controller) with an LCD and keypad. The W7220 can be configured with optional sensors.

The W7220 Economizer Module can be used as a standalone economizer module wired directly to a commercial set back space thermostat and sensors to provide Outdoor Air dry-bulb economizer control.

The W7220 Economizer Module can be connected to optional Sylk Bus sensors for single or differential enthalpy control. The W7220 Economizer Module provides power and communications on the Sylk Bus for the Sylk Bus sensors.

The W7220 Economizer Module automatically detects sensors by polling to determine which sensors are present. If a sensor loses communications after it has been detected, the W7220 Economizer indicates a device fail error on its LCD.

The Sylk Bus Sensor is a combination temperature and humidity sensor which is powered by and communicates on the Sylk Bus. Up to three sensors may be configured with the JADE™ Economizer Module. See page 2 for details.

CO2 Sensor (optional)

A CO2 sensor can be added for Demand Control Ventilation (DCV). Either an analog (2-10 Vdc) or a wall-mount Sylk bus TR40 CO2 sensor can be used with the Jade economizer.

PC MOD Tool (optional)

The PC MOD tool is connected to a personal computer and communicates with the Jade economizer controller via the Sylk bus. The W7220 PCMOD tool software is free and can be downloaded from the url in the Accessories section.

Some features on the Jade controller can only be enabled or disabled using the W7220 PC MOD tool. See the PC MOD tool options section in Table 5.

MOUNTING

This section describes the mounting procedures for the JADE™ Economizer module and the sensors.

Economizer Module Location and Mounting

IMPORTANT

Avoid mounting in areas where acid fumes or other deteriorating vapors can attack the metal parts of the module’s circuit board, or in areas where escaping gas or other explosive vapors are present.

IMPORTANT

The module must be mounted in a position that allows clearance for wiring, servicing, and removal.

Mount the Economizer module on any convenient interior location using the two mounting holes provided on the enclosure using #6 or #8 screws (screws are not provided and must be obtained separately). Use the dimensions in Fig. 1 on page 3 as a guide.

BEFORE INSTALLATION

Review the “Specifications” on page 2 before installing the The JADE™ Economizer System.

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.

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.

The Economizer module may be mounted in any orientation. However, mounting in the orientation shown in Fig. 1 on page 3 permits proper viewing of the LCD display and use of the keypad.

Sensor Location and Mounting

The JADE™ Economizer W7220 uses digital and communicating sensors for control.

number. The sensor is set for the appropriate type of sensing using the three position DIP switch located on the sensor. OA position is OFF, OFF, OFF; RA is ON, OFF, OFF and DA is OFF, ON, OFF. During installation the sensors are set for the usage desired. See “Sylk Bus Sensor Wiring” on page 7 for DIP switch details.

NOTE: The protective film on the dip switch is only nec-

essary during the factory assembly process. Simply push through the film to set the dip switches; this will not harm the device.

Once installed, a sensor can be changed to a different application by simply changing the DIP switch setting.

Sensor Mounting

The sensors can be mounted directly on to the sheet metal of unit or can be mounted in the air stream using the duct mounting kit (order separately).

The kit contains a rod to hold the sensor in the duct, a flange to secure the sensor rod to the duct wall and fill the hole and a gasket to prevent air from leaking through the duct wall. There are five (5) kits in each bag assembly. See Fig. 2.

The rod has slots for threading the wire to prevent loose or hanging wire in the duct and can be adjusted for 6 to 12 inch length. The flange has extended relief for ease of mounting. See Fig. 3.

Economizer Module Wiring Method

Wire the sensors and outputs, then wire the power connection.

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.

• All sensor wiring to the Sylk bus and analog sensors is polarity insensitive.

Prepare wiring for the terminal blocks, as follows:

1. Remove the plastic tabs from the side of the controller where the connectors will slide onto the PWA.

2. Strip 1/2 in. (13 mm) insulation from the conductor.

3. Cut a single wire to 3/16 in. (5 mm). Insert the wire in the

required terminal location and tighten the screw.

4. If two or more wires are being inserted into one terminal location, twist the wires together a minimum of three turns before inserting them to ensure proper electrical contact. See Fig. 5 on page 6.

5. Cut the twisted end of the wires to 3/16 in. (5 mm) before inserting them into the terminal and tightening the screw.

6. Pull on each wire in all terminals to check for good mechanical connection.

NOTE: When using the Sylkbus sensors there will be a

slight delay while the Jade controller and the sensor communicate. Analog sensors do not communicate on the Sylkbus and output a 20k ohm signal to the Jade controller so the response time is instantaneous.

NOTE: When using the C7400S (Sylk bus enthalpy)

sensor there is an operation that will allow test of the operation of the W7220 economizer when the outdoor air conditions (temperature and humidity) are too high for economizing.

1. Remove the C7250A dry bulb sensor from the OAT

terminals IF you are using temperature only economizing change over.

2. If you are using enthalpy change over and have a C7400S sensor with a date code prior to 1301, remove the sensor and replace it with one with a date code after

1301.

3. Connect a C7400S Sylk bus sensor to the S-Bus terminals (brown colored) on the W7220A Jade using 18 AWG to 22 AWG solid or stranded wires.

4. Check the STATUS screen for actual outdoor air (OA) temperature and OA humidity readings.

5. Change the 3-position DIP switch on the C7400S sensor from 1 OFF, 2 OFF, 3 OFF to 1 ON, 2 ON, 3 ON position and immediately back to 1 OFF, 2 OFF 3 OFF position.

6. The output of the C7400S sensor to the W7220A will be 40 ºF and 40 %RH which will allow the economizer to go into free cooling mode (economizing available).

7. Make sure you have 24 Vac on terminal Y1 In to simulate a call for cooling.

8. After 15 minutes the C7400S sensor will change back to the actual OA temperature and humidity.

NOTE: If you removed a dry bulb sensor, remove the

C7400S from the S-bus terminals and replace the OAT sensor onto the OAT terminals.

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 two (2) 2-position actuators (1 each on EXH1 and AUX1 O)

3. One (1) communicating and up to four (4) non-communicating and two (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.

CO2 Sensor Wiring

When using the C7232 Honeywell CO2 sensors the black and brown common wires are internally connected and only one is connected to "IAQ COM" on the Jade. Use the power from the Jade to power the CO2 sensor OR make sure the ground for the power supplies are common. See wiring diagram below for the C7232 and C7632 wiring diagrams.

NOTE: When using the C7632 (or any 0-10 Vdc CO

sor) with the Jade you will need to set the CO2ZERO to 400 ppm and the CO2SPAN to 1600 ppm in the ADVANCED SETUP menu.

NOTE: When using the TR40 CO
