Description
The EVCB Series is a combination controller and thermostat with
support for networked communications via the BACnet MS/TP or
Modbus protocol. The EVCB Series controller is compatible with both
TRL24 and TDU series thermostats. The Networkable Dual Duct VAV
Controller is designed for simple and accurate control of any variable
air volume box in a number of zone control configurations. Its field
configurable algorithms enable versatile implementation of required
control sequences.
