Configuring a VEC using the SBH - Verasys - LIT-12012371 - LC-SBH200-0 - Building automation software - Verasys System - 4.2

The Verasys Equipment Controller (VEC) is by default a change-over bypass system. You must change this to a VAV system. Complete the following procedures to check that the minimal settings have been performed.

1. Log in 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 Supply Air Temperature (SAT) appears properly.
   Note: For the unit to have control, you need at least one SAT sensor.
4. Navigate to the Details > Service > Factory tab. From this tab, complete the following actions:
   • Adjust the setup of the unit to the third-party equipment.
   • Set the number of stages of heating and cooling that the unit has.
   • If the VEC has control of the economizer, set it to Yes.
     Note: You must have an outside air temperature installed for the economizer to modulate.
   • Set the RTU controller type to VAV. It defaults to change-over bypass so you must change it.
