General Information RT-SVX24K-EN21 prevent over/under pressurization. The overall scheme will remain very similar to VAV units with Space Pressure Control with the exception of the dynamic Exhaust Enable Setpoint. For SZVAV an Exhaust Enable Setpoint must be selected during the 100% Fan Speed Command. Once selected, the difference between the Exhaust Enable Setpoint and Design OA Damper Minimum Position at 100% Fan Speed Command will be calculated.The difference calculated will be used as an offset and added to the Active Building Design OA Minimum Position Target in order to calculate the dynamic Exhaust Enable Target, which will be used throughout the Supply Fan Speed/OA Damper Position range. The Exhaust Enable Target could be above or below the Active Building Design OA Minimum Position TargetSetpoint, based on the Active Exhaust Enable Setpoint being set above or below the Building Design Minimum Position at 100% Fan Speed Command. Note that an Exhaust Enable Setpoint of 0% will result in the same effect on Exhaust Fan control as on VAV applications with and without Statitrac. Occupied Cooling Operation For normal cooling operation, cooling capacity will be staged or modulated in order to meet the calculated discharge air target setpoint. If the current active cooling capacity is controlling the discharge air within the deadband, no additional cooling capacity change will be requested. As the Discharge Air Temperature rises above the deadband, the algorithm will request additional capacity as required (additional compressors or economizer). As the Discharge AirTemperature falls below the deadband, the algorithm will request a reduction in active capacity. Default Economizer Operation By default, the unit will be setup to optimize the minimum supply fan speed capability during Economizer Only operation. If the economizer is able to meet the demand alone, due to desirable ambient conditions, the supply fan speed will be allowed to increase above the minimum prior to utilizing mechanical cooling if discharge air setpoint falls below the discharge air Lower Limit (Cooling) setpoint. Unoccupied Mode In Unoccupied mode the unit will utilize setback setpoints, 0% Minimum OA Damper position, and Auto Fan Mode operation as on normal CV units. The Supply Fan speed, and cooling and modulating types of heat, will be controlled to the discharge air target setpoint as is done during occupied periods. The Supply fan speed during staged heat control will be forced to 100% as on normal CV units. Occupied Heating Operation Occupied heating operation has two separate control sequences; staged and modulated. All staged heating types will drive the supply fan to maximum flow and stage heating to control to the Zone Heating Setpoint. For units with Hydronic and Gas heat, modulated SZVAV Heating. On an initial call for heating, the supply fan will drive to the minimum heating airflow. On an additional call for heating, the heat will control in order to meet the calculated discharge air target setpoint. As the load in the zone continues to request heat operation, the supply fan will ramp-up while the control maintains the heating discharge air temperature. Heating can be configured for either the energy saving SZVAV Heating solution as described above, or the traditional, less efficient CV Heating solution. Compressor (DX) Cooling Compressor control and protection schemes will function identical to that of a traditional unit. Normal compressor proving and disable input monitoring will remain in effect as well as normal 3-minute minimum on, off, and inter- stage timers. Also, all existing head pressure control schemes will be in effect. Cooling Sequence If the control determines that there is a need for active cooling capacity in order to meet the calculated discharge air target setpoint, once supply fan proving has been made, the unit will begin to stage compressors accordingly. Note that the compressor staging order will be based on unit configuration and compressor lead/lag status. Once the discharge air target setpoint calculation has reached the Minimum Setpoint and compressors are being utilized to meet the demand, as the discharge air target setpoint value continues to calculate lower the algorithm will begin to ramp the supply fan speed up toward 100%. Note that the supply fan speed will remain at the compressor stage’s associated minimum value (as described below) until the discharge air target setpoint value is calculated below the discharge air temperature Minimum Setpoint (limited discharge air target setpoint). As the cooling load in the zone decreases the zone cooling algorithm will reduce the speed of the fan down to minimum per compressor stage and control the compressors accordingly. As the compressors begin to de-energize, the supply fan speed will fall back to the Cooling Stage’s associated minimum fan speed, but not below. As the load in the zone continues to drop, cooling capacity will be reduced in order to maintain the discharge air within the ± ½ discharge air target deadband. Fault Detection and Diagnostics Fault Detection of the Outdoor Air Damper will be evaluated based on the commanded position of the damper compared to the feedback position of the damper.
General Information 22RT-SVX24K-EN The damper is commanded to a position based on a 2-10 VDC signal. If the Damper position is outside of ±10% of the commanded position, a diagnostic is generated. Unit Not Economizing when it should be: The Unit is operating in Cooling Mode, Economizing is enabled and/or Mechanical Cooling is enabled. If the Commanded Economizer Position is greater than Current Economizer Feedback Position + 10% for 5 continuous minutes, Unit Not Economizing when it should be diagnostic is generated. Unit Economizing when it should not be: The unit is operating in Cooling Mode, Economizing is enabled and or Mechanical Cooling is enabled. If the commanded Economizer Position is less than the current Economizer Feedback Position - 10% for 5 continuous minutes, Unit Economizing When it should not be diagnostic is generated. Outdoor Air Damper Not Modulating The unit is operating in Ventilation Only Mode - not attempting to Economize and the Commanded Damper Position is greater than the Current Damper Feedback Position + 10% for 5 continuous minutes, Outdoor Air Damper Not Modulating diagnostic is generated. Excessive Outdoor Air The unit is operating in Ventilation Only Mode - not attempting to Economize and the Commanded Damper Position is less than the Current Damper Feedback Position - 10% for 5 continuous minutes. Excessive Outdoor Air diagnostic is generated. To change the Economizer Control Function to dry bulb, go to the Configuration Menu on the Human Interface Module and set Comparative Enthalpy to Not Installed.This allows the user to select dry bulb under the Economizer Control Function which is a Submenu of the Setup Menu. For additional instructions please see the Programming and Troubleshooting Guide.
