The mH-V4 module is a four-channel executive module that controls the operation of solenoid valves connected to the module outputs and is adapted to work with mH-S4 temperature sensor modules. The module is mounted in the switchboard and occupies a field of 5 modules, and the module's supply voltage is 230VAC. The module is suitable for controlling solenoid valves in heating circuits (usually installed on the collector) with a coil voltage of 230VAC and works on the on-off principle, regardless of the main touch panel (it is an autonomous pair with the mH-S4 module located on the same level). If it is necessary to connect more temperature sensors, several mH-V4 modules can be used, but remember that they must be modules of the next levels (mH-V4 - level 1, mH-V4-level 2 ...).
