Room controller

The MACH® room controller RCU-02


The room control unit is the heart of the MACH® room automation system. The unit is a standard DIN size that plugs into the room’s distribution board. It incorporates a 32bit microprocessor giving control of the heating or air conditioning circuit and providing communications, by low voltage (5v) twisted pair cable, inside the room to the other MACH® modules and outside the room back to the Server.


The room controller incorporates flash memory so that even if there is an interruption to the communications back to the central server, it will continue to operate correctly.

The communications circuits are not polarity sensitive and are short circuit tolerant for ease of installation and reliability.
