JADE™ Economizer Module (MODEL W7220) PRODUCT DATA System Components The JADE™ Economizer System includes an Economizer Module, 20k mixed air sensor, damper actuator, an optional CO2 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. 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. Sylk Bus Sensors (optional) 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.

Review the “Specifications” on page 2 before installing the The JADE™ Economizer System. Sensor Location and Mounting When Installing This Product 1. 2. 3. 4. The JADE™ Economizer W7220 uses digital and communicating sensors for control. The C7250 temperature sensors (MAa and OAb) are 20k NTC. A MA 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. Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition. Check ratings given in instructions and on the product to ensure the product is suitable for your application. Installer must be a trained, experienced service technician. After installation is complete, check out product operation as provided in these instructions. Optional OA, RAc and DAd 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 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. a MA = Mixed Air OA = Outdoor Air c RA = Return Air d DA = Discharge Air b 3 63-2700—10 JADE™ ECONOMIZER MODULE 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. WIRE HOLDER Sensor Mounting LENGTH ADJUSTS 6-12 INCHES 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. EXTENDED RELIEF (FOR CORRECT MOUNTING) M32282A Fig. 3. Duct Mounting Adjustments.

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. 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. Check the STATUS screen for actual outdoor air (OA) temperature and OA humidity readings. 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. 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). Make sure you have 24 Vac on terminal Y1 In to simulate a call for cooling. 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. SYLK BUS 2 PIN SIDE CONNECTOR M32271B Fig. 7.

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 ALARM SENSITIVITY Low 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 cooling AUTO coil DAMPER AIA THRESHOLD 15 degrees The operator can choose if the economizer control sensor (normally 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. 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. Table 5 illustrates the complete hierarchy. Your menu parameters may be different depending on your configuration. For example if you do not have a DCV (CO2) sensor, then none of the DCV parameters appear. b When values are displayed, pressing and holding the or button causes the display to automatically increment. n/a = not applicable d ERV Operation: When in Cooling mode AND the conditions are NOT OK for economizing - the ERV terminal will be energized. In the Heating mode the ERV terminal will be energized when the OA is below the ERV OAT setpoint in the setpoint menu. e When used with Honeywell communicating actuator the damper out is reported in XX.X% open versus XX.X Vdc. f After 10 minutes without a command or mode change, the controller will change to normal operation. c 63-2700—10 24 JADE™ ECONOMIZER MODULE Table 6.

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. Enthalpy Settings When 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. State 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. Fan Speed OCC Low Y1 Low Y2 High W High 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. 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: 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. 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 OR • If the call for additional cooling in the space has not been satisfied then the first stage of mechanical cooling will be enabled through Y1 Out or Y2 Out. 29 63-2700—10 JADE™ ECONOMIZER MODULE CHECKOUT a Inspect all wiring connections at the Economizer module’s terminals, and verify compliance with the installation wiring diagrams.

Power Up After the module is mounted and wired, apply power. Initial Menu Display On initial start up, Honeywell displays on the first line and Economizer W7220 on the second line. After a brief pause, the revision of the software appears on the first line and the second line will be blank. CAUTION Equipment damage may result. Power Loss (Outage or Brownout) Be sure to allow enough time for compressor startup and shutdown between checkout tests so that you do not short-cycle the compressors. All setpoints and advanced settings are restoreda after any power loss or interruption. 63-2700—10 All settings are stored in non-volatile flash memory. 30 JADE™ ECONOMIZER MODULE TROUBLESHOOTING Clearing Alarms Once the alarm has been identified and the cause has been removed (e.g. replaced faulty sensor), the alarm can be cleared from the display. Alarms The Economizer module provides alarm messages that display on the 2-line LCD. 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. 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. 6. 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. 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. You can also navigate to the Alarms menu at any time. 31 63-2700—10 JADE™ ECONOMIZER MODULE By using this Honeywell literature, you agree that Honeywell will have no liability for any damages arising out of your use or modification to, the literature.
