The following describes the supported features and modes for the changeover bypass (COBP) systems. The system consists of the following components:
- COBP zone damper controllers
- Bypass damper controller
- VEC
- VZC
- RTU, heat pump, or split system equipment with SMART Equipment controls
The Verasys system uses the VEC or the RTU, heat pump, or split system with SMART Equipment controls. The VEC board interfaces with non-smart equipment RTUs on a zoning system. The VEC controller communicates in the same way as an intelligent thermostat controller so the unit must have a thermostat interface.
COBP systems use a zone voting logic. The following sections provide details about this logic.
