Arbonia Controller board for MB control MB-ECM-S ZE0205 0002

For ModBus RTU control, for wall control and remote control, not mounted, acts as an interface: fan coil - control - building management system, for ModBus RTU in accordance with the master / slave logic, inputs: T1 = air temperature sensor, T2 = change-over sensor, T3 = minimum temperature sensor (heating and cooling circuit), outputs: actuator heating, actuator cooling, output for electronic filter or electrical auxiliary heating, for internal BUS based on master / slave logic (this enables the use of several fan coils on one controller), BUS: RS485, potential-free contacts: for change-over signal, for window contact / presence sensor or the like, a further contact that can be optionally (via DIP switch) normally open or normally closed, 0 - 10 V output, various detailed settings are possible via 10 DIP switches, 230 V / 50 Hz mains voltage.
