Pre-assembled pump group for fixed point regulation and circulation of mixed fluid. Allows the circulation of the thermal fluid, coming from the primary circuit, by keeping the temperature at a pre-set value (fixed point) through the help of a mixing valve with thermostatic element. It is used in heating systems in general and radiant panel systems. The group is composed of a pump, thermostatic mixing valve, flow temperature gauge, manual air vent, fittings for secondary distribution manifolds. The group can be installed with the secondary distribution manifolds on the right or the left. Available with two temperature adjustment ranges (3060 °C for 17B.N and 18B.N series, 2550 °C for 17B.1.N and 18B.1.N series). The groups 18B.N and 18B.1.N are equipped with 07B.N. series differential by-pass kit as standard.
