DIRECT MOUNT ECONOMIZER OPERATION

GENERAL This accessory economizer package is designed to save energy costs by using outdoor air for cooling and ventilation in place of mechanical cooling whenever possible. The economizer continuously monitors indoor and outdoor air conditions and compares them to a user-selected setpoint to determine if free cooling is available. The economizer utilizes a fully-modulating damper actuator, which will control the outside air damper and return air damper in order to maintain a factory-set mixed air/discharge air temperature.
ACCESSORIES
(-)XRX-BV01 – Dual Enthalpy Upgrade Kit For maximum energy savings, this upgrade kit will allow the economizer to compare the outdoor air enthalpy to the return air enthalpy, instead of a user-selected setpoint to determine if “free cooling” is available. This Sylk Bus Sensor is a combination temperature and humidity sensor which is powered by and communicates on the two-wire communication bus of the W7220 economizer logic module. All OA (Outside Air) and RA (Return Air) sensors are the same. Sensor must be set for the type of sensing using the three DIP switches located on the sensor during INSTALLATION.

(-)XRX-AR02 – Wall-Mounted Carbon Dioxide Sensor For installations requiring Demand Control Ventilation (DCV) based upon indoor air levels of carbon dioxide (CO2). When the unit supply fan is running, the CO2 sensor modulates the outside air damper to maintain a user-selected CO2 level inside the occupied space. Energy savings are achieved by not bringing in excessive amounts of outdoor air when the indoor air conditions are suitable. Energy savings can be substantial on buildings with highly variable occupancy rates.
NOTE: The (-)XRX-AR02 has a default setting of a 2-10 Vdc output for a 500-1500 ppm CO2 input. The W7220 economizer controller requires jumper pins on the sensor to be relocated to provide a 0-2000 ppm input.

Notes
Setpoint determines where the economizer will modulate the OA damper to maintain the mixed air temperature.
Setpoint determines outdoor temperature when the mechanical cooling cannot be turned on. Commonly referred to as the Compressor lockout.
Setpoint determines where the economizer will assume outdoor air temperature is good for free cooling; e.g.; at 63ºF unit will economizer at 62ºF and below and not economize at 64ºF and above. There is a 2ºF deadband.
Drybulb Differential will only show if using dual drybulb, i.e. when an ourdoor air temperature air sensor C7250 is attached to OAT terminals, and a C7400S sensor is wirred to S-BUS and configured for RAT (Return Air). Free cooling will be assumed whenever OA temperature is at or below RAT minus this drybulb differential setting.
Does not display if a field installed Dual Enthalpy kit is connected. Enthalpy boundary “curves” for economizing using single enthalpy comparison between outdoor air enthalpy and setpoint.
Displays ONLY if field installed CO2 sensor is connected. Setpoint for Demand Control Ventilation of space. Above the setpoint, the OA dampers will modulate open to bring in additional OA to maintain a space ppm level below the setpoint.
Displays ONLY if a CO2 sensor is NOT connected.
With 2-speed fan units MIN POS L (low speed fan) and MIN POS H (high speed fan) settings are required. Default for MIN POS L is 3.2V and MIN POS H is 2.8V
Displays only if a field installed CO2 sensor is connected. Used for Vbz (ventilation max cfm) setpoint. VENTMAX is the same setting as MIN POS would be if you did not have the CO2 sensor.
If OA, MA, RA and CO2 sensors are connected and DCV CAL ENABLE is set to AUTO mode, the OA dampers are controlled by CFM and displays from 100 to 9990 cfm.
With 2-speed fan units VENTMAX L (low speed fan) and VENTMAX H (high speed fan) settings are required. Default for VENTMAX L is 3.2V and VENTMAX H is 2.8V.
Dis plays only if field in stalled CO2 sen sor is con nected. Used for Va (ven ti la tion min cfm) setpoint. This is the ven ti la tion re quire ment for less than max i mum oc cu pancy of the space.
If OA, MA, RA and CO2 sen sors are con nected and DCV CAL EN ABLE is set to AUTO mode, the OA damp ers are con trolled by CFM and dis plays from 100 to 9990 cfm.
With 2-speed fan units VENTMIN L (low speed fan) and VENTMIN H (high speed fan) set tings are re quired. De fault for VENTMIN L is 2.5V and VENTMIN H is 2.25V.
Only when AUX1 O = ERV
Setpoint for OA damper position when exhaust fan 1 is powered by the economizer. With 2-speed fan units Exh1 L (low speed fan) and Exh1 H (high speed fan) settings are required. Default for Exh1 L is 65% and Exh1 H is 50%.
Setpoint for OA damper position when exhaust fan 2 is powered by the economizer. Only used when AUX1 O is set to EHX2. With 2-speed fan units Exh2 L (low speed fan) and Exh2 H (high speed fan) settings are required. Default for Exh2 L is 80% and Exh2 H is 75%.

When AUX1 O is set to SYS and there is any alarm (e.g., failed sensors, etc.), the AUX1 O terminal has 24 Vac out. Voltage received by Actuator is above expected range Voltage received by Actuator is below expected range Actuator stopped before achieving commanded position

Alarms The 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 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. 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 alarm still exists after you clear it, it redisplays within 5 seconds.

TYPICAL ADJUSTMENTS 1. Economizer ENTH CURVE Setpoint
a. Only the coolest, driest outside air is used for economizer operation when parameter “ES5” is selected on the SETPOINT MENU. Select parameter “ES1” on the SETPOINT MENU for the greatest energy savings.
b. Adjustments are ES1, ES2, ES3, ES4, ES5. c. “ES3” is the default setting. d. Economizer ENTH CURVE Setpoint can be adjusted at
any time and may need adjustment for jobsite conditions.

e. Single enthalpy strategy: If outdoor air enthalpy is lower than the ENTH CURVE setpoint, then free cooling is available.
f. Dual enthalpy strategy: ENTH CURVE Setpoint is not used. If outdoor air enthalpy is lower than return air enthalpy, then free cooling is available. There is also a high limit boundary for dual enthalpy. The high limit boundary is “ES1” when there are no stages of mechanical cooling energized and “HL” when a compressor stage is energized.

NOTES
1. This economizer requires a two-stage thermostat.
2. When diagnosing the system, the best results are obtained by first putting the fan setting on the Thermostat to the “Continuous Fan” mode.
3. Operation of the optional power exhaust only depends upon the supply fan running and the damper position (it is possible to set the minimum position high enough to engage the power exhaust in the heating mode).

4. Upon loss of power to the unit or economizer, the outside air damper will spring close shut in about 5 seconds.
5. Compressor Time Delays, Compressor Interstage Delays are not provided by the economizer controller.

B With STG3 DLY in ADVANCED SETUP MENU at 2.0 hours, the 2nd stage of mechanical cooling Y2-O can be energized after a 2 hour delay if the call for Y1-I and Y2-I have not been satisfied.
C The CO2 sensor has a relay output that is active when the CO2 level is above 1200ppm that can be used to energize the indoor fan through the “G” thermostat input of the unit even if there is not a call for fan, cooling or heating by the room thermostat. Additional field wiring is required to enable this option.
D AUX2-I is used only on heat pump models to indicate unit is in heat pump (heating) mode.

e Unoccupied Mode is only available by field wiring a normally open (NO) relay in the “G” signal wiring between the unit and economizer. A thermostat with an occupied output is required which energizes the relay when the space is occupied. The relay interrupts the 24 volt “G” signal from the unit indoor fan when the space is unoccupied.
