Information on room temperature hook-up (RS function) for remote control units
Never activate the RS function in the case of underfloor heating circuits
(inertia).
In heating systems that include one heating circuit without mixers and
heating circuits with mixers, the RS function must only affect the heat-
ing circuits with mixers.
