K C A wired basic zoning system Zoning System R/C allows for individualised temperature control of different zones using the same air treatment equipment to provide increased comfort in each one. KCA control panel is compatible with any duct-type direct expansion air handling unit and can control from 1 to 6 different zones. The control is carried out by means of digital thermostats linked by RS485 communication bus to a control panel that operates the different motorised (24 Vdc) zone dampers. Thermostats that work by 485 bus minimize wiring regarding to the conventional wired installations (only 2 wires among the thermostats). Ecologically friendly: Zoning System R/C provides a rational use of energy, both from an economic and environmental point of view.
