Wireless Digital Head Elektrobock PH-HD23 is a component controlling the valve on radiator heating. The head can operate autonomously or in wireless mode, where it is controlled by a central unit. The head measures the current temperature with an internal sensor and, based on the difference from the desired temperature, adjusts the valve by closing or opening it. Information about the valve position, given temperature, and battery status is transmitted to the central unit.
