I/O extension module flex 400

I/O module for extending the functions of controllers from the REGULA series with flexibility
The flex 400 is designed to extend the functions of controllers from the grandis family by adding additional inputs and outputs. This enables the implementation of an additional heating circuit, for example, or a fresh water station, additional multi-function controllers and an additional energy yield measurement function (depending on the controller software).

    Connection of up to 2 flex 400 modules
    Control of 2 additional heating circuits
    (1 heating circuit per flex 400))
    Independent yield measurements (1 per flex 400)
  • grandis 650 HK:
    Connection of up to 4 flex 400 modules
    Control of 4 additional heating circuits
    (1 heating circuit per pro flex 400)
    Independent yield measurements (1 per flex 400) If not assigned as a heating circuit, up to 3 additional multifunction controllers *
