    The MC300 multi heater digital controller can be connected to each heaters slave PCB in various ways depending on your application setup. The maximum cable length between each heater is 100m. Unlike other multi-zone systems, the MC300 Multi setup keeps costs extremely low as the factory fitted slave PCB connects each heater and not by another slave controller.

    Energy-saving heating control

    Optimum start technology is available that will continually monitor the heating systems previous performance to determine the optimum time to turn the heating on to raise the space temperature to the required level for when occupancy begins. Optimum stop can also be selected which can save energy at the end of the heating period.

  • Features
