Floor Heating Module

The HDL-MFH06.432 is a floor heating controller with 6 relay output channels and 6 x 0-10V analog output channels. It has a temperature sensor input port to which you can connect the digital temperature sensor DS18B20 (supplied by HDL). It can work in two modes, i.e. 'slave control' and 'fully control'
