Exposed Return Temperature Limiter Control Set

Used for small areas, bathrooms, conservatories and extensions which are not more then 10m² (at 200mm pipe centre to centre distances).

Function
Return temperature limiter are installed in the return of a radiator or underfloor heating loop. When the return flow temperature rises the valve closes and the flow through the heating loop is throttled. When the return flow temperature decreases the valve opens and the flow increases.

Application
The Thera-RTL limits the return flow temperature of radiators or, in case of combined radiator/underfloor heating systems, the return flow temperature of underfloor heating loops.
The system designer has to make sure that the supply temperature is suitable for the floor design of the underfloor heating system. A too high supply temperature may result in damage to the floor.
