The mH-S4 module is a four-channel controller cooperating with digital temperature sensors measuring temperatures in the range from +5 to +40 degrees with an accuracy of 0.1 degrees and is adapted to operate with mH-V4 executive modules controlling solenoid valves in the heating circuit. The module is mounted in the switchboard and takes up a field of 5 modules, and the module's supply voltage is 24 V. The FTP cables from the temperature sensors are connected to the module (one cable for each sensor). The module works autonomously based on detailed settings made from the touch panel (independently set temperature and hysteresis for each room) and based on these settings directly controls the executive module that regulates the temperature in the room. If it is necessary to connect more temperature sensors, several mH-S4 modules can be used, but remember that they must be modules of successive levels (mH-S4 - level 1, mH-S4-level 2, ...).
