The return temperature limiter RTL is mainly used to limit the return temperature for radiators or combined floor-radiator heating systems for temperature control of smaller floor areas (up to approx. 15 m2).
Heating systems
The maximum limitation of the return temperature.
Automatic flow limitation with Eclipse valves.
Shut-off.
The temperature range is limited on both ends and can be blocked using covered stop clips.
Proportional controller without auxilliary energy.
