sensor is required for all applications and is mounted in the mixed air section of a rooftop unit either directly to the sheet metal using self tapping sheet metal screws or in the air stream using the duct mounting kit. Duct mount kit is part number 50053060-001.Optional OA, RAa and DAb Sylkbus sensors communicate with the W7220 on the two-wire communication bus and can either be wired using a two pin header or using a side connector. Each Sylkbus sensor includes a two pin side connector with the packaging. The SKU number of the Sylkbus sensor is C7400S. All OA, RA and DA sensors are the same SKU 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 necessary 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 MountingThe 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.

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.

63-2700–11

JADETM ECONOMIZER MODULE

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) 2position 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 WiringWhen 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 CO2 sensor) 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 CO2 sensor set the address on the TR40-CO2 to 6. Only one TR40 CO2 sensor can be used with the Jade economizer controller. Address 6 is for a CO2 sensor, address 11 is for a communicating actuator.

Menu Structure

Table 5 on page 19 illustrates the complete hierarchy of menus and parameters for the JADETM Economizer system.

The Menus in display order are: · STATUS · SETPOINTS · SYSTEM SETUP · ADVANCED SETUP · CHECKOUT · ALARMS

IMPORTANTTable 5 on page 19 illustrates the complete hierarchy. Your menu parameters will be different depending on your configuration.

For example if you do not have a DCV (CO2) sensor, then none of the DCV parameters appear and only MIN POS will display. If you have a CO2 sensor, the DCV MIN and DCV MAX will appear AND if you have 2 speed fan DCV MIN (high and low speed) and DCV MAX (high and low speed will appear).

SETUP AND CONFIGURATION

Before being placed into service, the JADETM Economizer module must be setup and configured for the installed system.IMPORTANT During setup, the Economizer module is live at all times.The setup process uses a hierarchical menu structure that is easy to use. You press the and arrow buttons to move forward and backward through the menus and press the button to select and confirm setup item changes.

Time-out and ScreensaverWhen no buttons have been pressed for 10 minutes, the LCD displays a screen saver, which cycles through the Status items. Each Status items displays in turn and cycles to the next item after 5 seconds.

ACTUATOR SLIPPAGE Enabled ALARM

Enabled or Disabled

Alarms if the actuator becomes disconnected from the damper or is slipping on the shaft. If Enabled, the Jade system will complete a system air temperature check. If there is the expected change in system air temperature, then Jade assumes the actuator is connected to the damper. If the expected system air temperature changes do not occur, then an actuator slippage alarm is displayed on the Jade LCD. Found on the configuration page of the Trade version.

ACTUATOR SLIPPAGE Low ALARM SENSITIVITY

Low, Standard or High

Sensitivity can be set to HIGH, STANDARD or LOW. High means the system will check 5 times for the damper to move before displaying the alarm. Standard is 10 times before the alarm is displayed. Low is 20 times before the alarm is displayed. Found on the economizer page of the Trade version.

LOCATION OF ECONOMIZER CONTROL SENSOR

Before the Before coil or The operator can choose if the economizer control sensor (normally

cooling coil AUTO

referred to as the Mixed air sensor) is placed in the mixed air (before

the coil) or Auto in the case the sensor is placed after the cooling coil.

Found on the configuration page of the Trade version.

DAMPER AIA THRESHOLD

15 degrees 5 to 40 degrees

Damper threshold feature (Adaptive Integral Action) is the difference in the mixed air temperature reported by the MAT sensor and the MAT setpoint. Lower (2 degrees) transfer rate between the actual MAT sensor reading and the MAT setpoint normally means the damper is closing and opening faster. Larger transfer rate (up to 20 degrees) between the sensor reading and the setpoint normally means the damper is opening and closing slower. Used in applications where there is a large MA space or there is a long duct between the OA and the MA causing a delay. Found on the economizer page of the Trade version.

Two-Speed Fan Operation

Enthalpy SettingsWhen the OA temperature, enthalpy and dew point are below the respective setpoints, the Outdoor Air can be used for economizing. Fig. 22 shows the new single enthalpy boundaries in the W7220. There are 5 boundaries (setpoints ES1 through ES5), which are defined by dry bulb temperature, enthalpy and dew point.Refer to Table 15 for the ENTH CURVE setpoint values.To use enthalpy the W7220 must have a C7400S Sylkbus sensor for OA. The W7220 calculates the enthalpy and dew point using the OA temperature and humidity input from the OA sensor. When the OA temperature, OA humidity and OA dew point are all below the selected boundary, the economizer sets the economizing mode to YES, economizing is available.

The later versions of the W7220 Jade controller have the capability to work with a system using a 2-speed supply fan. The W7220 does not control the supply directly but uses the following input status to determine the speed of the supply fan and controls the OA damper to the required position.

OCC Y1 Y2 W

State

Low Low High High

Fan Speed

The W (heating mode) is not controlled by the W7220 but it requires the status to know where to position the OA damper for minimum position for the fan speed.

When conditions are above the selected boundary, the conditions are not good to economize and the mode is set to NO.Fig. 22 shows the 5 current boundaries. There is also a high limit boundary for differential enthalpy. The high limit boundary is ES1 when there are no stages of mechanical cooling energized and HL when a compressor stage is energized.

The 2 speed fan delay is available when the system is programmed for 2 speed fan (in the System Setup menu item). The 2 speed fan delay is defaulted to 5 minutes and can be changed in the Advanced Setup menu item. When the unit has a call for Y1 In and in the free cooling mode and there is a call for Y2 In, the 2-speed fan delay starts and the OA damper will modulate 100% open, the supply fan should be set to high speed by the unit controller. After the delay one of two actions will happen:

Table 15 provides the values for each boundary limit.

· The Y2 In call will be satisfied with the damper 100% open and fan on high speed and the call will turn off

TROUBLESHOOTING

AlarmsThe Economizer module provides alarm messages that display on the 2-line LCD.

NOTE:

Upon power up, the module waits 60 minutes before checking for alarms. This allows time for all the configured devices (e.g. sensors, actuator) to become operational. The exception is the MA sensor which will alarm immediately.

If one or more alarms are present and there has been no keypad activity for at least 5 minutes, the Alarms menu displays and cycles through the active alarms.

You can also navigate to the Alarms menu at any time.

Clearing AlarmsOnce the alarm has been identified and the cause has been removed (e.g. replaced faulty sensor), the alarm can be cleared from the display.

To clear an alarm, perform the following: 1. Navigate to the desired alarm. 2. Press the button.3. ERASE? displays. 4. Press the button.5. ALARM ERASED displays.

6. Press the

button (MenuUp/Exit) to complete

the action and return to the previous menu.

NOTE: If an the alarm still exists after you clear it, it redisplays within 5 seconds.
