783 | Fixed-point mixing unit

Pump group with variable point mixing, complete with a 3-way mixing valve regulated by a three-point modulating bidirectional rotary electric actuator, connectable to weather-compensated controllers; the valve features a bypass that draws water from the system return and feeds it into the flow circuit to achieve the desired fluid temperature. The circulator, with 1 1/2” connections, can be asynchronous (not for sale in the EU) or electronic. The pump group is equipped with two ball shut-off valves with built-in thermometers for instantaneous flow and return temperature readings (a check valve is integrated into the return ball valve). The pump group can be ordered without a circulator, or with the flow circulator on the right or left (in case of on-site changes, please follow the instructions in the technical data sheet included in the packaging); the unit is supplied with a black EPP insulating shell. The supply includes actuator art. 787 (specify 230 or 24 V voltage). Technical datasheet Instruction sheet Declaration of conformity

NOTE: in case of reduction for the boiler inlet connection, use art. 789. Double-chamber brass manifold suitable for pump groups art. R001-R002-R003, complete with black EPP insulation shell. Art. 785 manifolds can be used individually or connected in series (up to 6) to serve multiple circuits, simplifying installation and reducing the overall footprint. The package includes nuts, bolts, and two O-rings for closing a single manifold or connecting multiple manifolds together. NOTE: art. 790 end caps and art. 788 mounting bracket are not included.
