HERZ Design MINI thermostatic head M28×1.5, 0–30 °C, 1920030

HERZ Design MINI 1920030 is a compact thermostatic radiator head designed for automatic room temperature control together with HERZ thermostatic radiator valves featuring an M28 × 1.5 connection.
The thermostatic head is equipped with a liquid sensor that continuously reacts to changes in room temperature and regulates the heating-water flow through the radiator accordingly. This helps maintain the selected room temperature and reduces unnecessary overheating.
The HERZ Design MINI features particularly compact dimensions. The head is only 75 mm long and the handwheel diameter is 45 mm, making it suitable for radiators installed where available space is limited.
The temperature adjustment range is 0–30 °C. The thermostatic head features a mechanical “0” shut-off position as well as a frost-protection setting. The setpoint range can be limited or locked using HERZ limiting pins 1955102, available separately.
