Configuring a VEC for COBP using the SBH - Verasys - LIT-12012371 - LC-SBH300-0 - Building automation software - Verasys System - 5.1

The VEC is by default a COBP system. Partial factory setup is already completed. Complete the following procedures to check that the minimal settings have been performed.

1. Log on to the SBH.
2. From the device list screen, select VEC. The VEC home page and the VEC menu structure appear.
3. The VEC home page provides an overview of the status of the unit. Check that the SAT sensor reading is correct.
   Note: For the unit to have control, you need minimum one SAT sensor.
4. Navigate to the Details > Service > Factory tab to adjust the setup of the unit to the third-party equipment.
   1. Set the number of stages of heating and cooling that the unit has.
   2. If the VEC controls the economizer, set it to yes.
      Note: An outside air temperature is required for the economizer to modulate.
   3. Set the RTU controller type to COBP.
   4. Variable speed drive should be set to false if a BYP200 is used. If you use a variable speed fan to control duct static pressure, instead of a BYP200, variable speed drive can be set to true. The VEC100 must have a discharge air duct static pressure sensor connected and the RTU must have a variable frequency drive that the VEC100 can control. Refer to your specific VEC100 application note for wiring details.
