Kele Constant Volume Zoning System

 

The technologically advanced Kele KTEC Zoning Control System provides efficient space temperature control for constant volume zoning systems in multi-zone heating and cooling applications. This cost-effective zoning control system can operate as a stand-alone system, or it can be mapped into a supervisory controller via a BACnet, Master-Slave/Token-Passing (MS/TP) Bus to enable remote monitoring and programmability within a Building Automation System (BAS).
