C221-01
C221 is a versatile control unit specifically designed for individual room temperature, VAV and zone control applications. The control unit can be connected to any system that supports Modbus RTU protocol by using the RS-485 connection. The bus is galvanically isolated from the controller’s other electronics. Bus end termination and polarisation are built in and can be activated with dip switches.
