Underfloor heating return temperature limiter thermostat with UBG valve insert.
The return temperature control set RTL is a regulator that maintains the set water temperature in the underfloor heating system. The kit is used to maintain floor temperature in mixed heating systems, underfloor heating / radiators.
A description of operation:
The return temperature limiter RTL is a self-acting regulator for regulating return temperature of a radiator or underfloor heating loop. Water temperature is transferred from the valve body to the sensor. If the temperature set at the head is below the water temperature, the regulator closes the flow and if the higher regulator opens flow.
