Wet rotor electronic circulator designed for the circulation of drinkable hot water in residential building service. The permanent magnet synchronous motor and electronics with the variable frequency drive automatically adapt the performance to the actual requirements of the system, to save energy and protect against water hammer action. It is designed for simple configuration and has a sequential key for scrolling through the nine operating modes:
three for proportional pressure,
three for constant pressure, and three for constant speed curves.
All the models have a brass air vent plug and the the manual deblocking of the motor shaft. Threaded suction and delivery ports. Bronze pump body. Electronics protected against water ingress with IPX5 protection. No overload protection required. The included calcium removal cartridge keeps the motor shaft in perfect condition, preventing the normal formation of limescale that it can be generated inside the circulator if some air bubbles are present during the first installation. 5 years warranty.
