The set is designed to limit the return temperature in underfloor heating systems and systems combining underfloor heating with other radiators. To prevent damage to the floor covering, it is necessary to ensure the correct supply temperature value. The temperature limiter can be set for a temperature range of 20...50 °C. The adjustable thermostatic head protrudes from the casing.

The limiter is installed on the return side of radiators or underfloor heating. The flow through the valve is controlled according to the temperature of the passing water. As soon as the return water temperature rises, the valve reduces the flow. If the temperature drops, the valve increases the flow.
