This actuator can be used in 3 or 2 point mode according to the wiring diagram it is used. In 3 point mode the actuator is used to motorize all the threaded 3- and 4-way mixing valves and all the motorizable regulating groups DN 20, DN 25 and DN 32. In 2 point mode the actuator can be combined to all the 3-way threaded mixing valves to be used in on-off mode as diverting valves. The rotation angle is 90°. At the end of the rotation, the electric supply is cut off by the end microswitch. If necessary, by pressing the central knob, the actuator can be set in manual mode: the operation unlocks the gear system and makes it possible to manually rotate the actuator and the connected valve. Available, according to the models, with 120 and 60 s rotation times, with and without auxiliary microswitch. Can be connected, depending on the models, to on-off devices (i.e. thermostats) or 3 point weather compensated controllers to regulate the temperature.
