The Siemens RTN51 thermostatic head is designed for room temperature control. The control of the head is manual, using a rotary knob. A fully enclosed version and an anti-frost position are available. Installation is quick thanks to the pull nut and the operation is completely maintenance-free. The adjustable temperature range is 0 to 28 °C (scale 0-5). The head also has stops for the selected minimum and maximum setting values. The built-in liquid sensor reacts quickly to changes in room temperature. The surface is matt.

The thermostatic head can be used for Siemens VDN, VEN and VUN valves, as well as for VPD and VPE combination valves. It is also compatible with Heimeier brand valves, Cazzaniga, Oventrop M30 × 1.5, Honeywell-Braukmann, MNG and TA type TBV-C, without the need for an adapter. Furthermore, it can be used for valves with overflow nut and M30 × 1.5 mm thread, also without adapter. In case of combination with valves from other manufacturers, a suitable AV series adapter must be used.
