The control station has the task of bringing the liquid temperature of the main circuit (boiler) to the adjustable desired value in the secondary circuit (floorheating). The RS 1 is composed of components element and can (with rotating nipples 1 ") connected in a simple way directly to our distribution list for floorheating. The versatility of this control station is particularly evident in the case of systems with mixed circuits: high temperature (radiator system) and low temperature (floor heating). This is the classic case of a residential unit in general. FBH and bathrooms with radiators (towel heat etc.). To carry out this investment, a manifold pair with simple branches for radiators need only be connected at the input of the RS 1.
