Valve Drive Controller, 4-fold

For the control of heating and cooling applications in the room, such as radiator, floor heating or cooling ceiling. The device has 4 channels each for the independent control of a heating or cooling application. Each channel has an electronic valve output for the control of a thermoelectric valve drive, as well as 3 inputs to detect and monitor the room status (use forwindow contact, dew point sensor, level sensor or temperature sensor). Also it is possible to connect one analog room control unit (SAR/A) to the inputs of each channel. Each channel has its own integrated room temperature controller for the control of the room temperature, which can be used directly to control the outputs of the device. The VC/S 4.2.1 features an easy to use manual operation. Both devices support the ABB i-bus® Tool for advanced diagnosis and improved commissioning.
