The hydraulic group is a low-temperature system controlled by a fixed-point thermostatic controller that determines a constant flow temperature for the underfloor heating circuit. It incorporates a contact thermostat system to be placed in the outflow pipe, which must precede the electrical supply of the circulating pump, and it stops it if the temperature exceeds the determined value. The valve has an integrated low temperature hydraulic circuit, most of the return circuit is routed to send to the circuit. The mixing group allows maintenance of the circulator without the need to empty the circuit.
The unit with a 3/4" solar circulation pump, fully assembled and tested, consists of:
Flow meter with flow regulation with filling and draining valves.
High efficiency solar synchronous circulation pump with cables.
3-way flanged ball valve with 10 mbar check valve (which can be excluded by turning the handle 45°) supplied with thermometer in the handle (coded blue, range 0°C to 120°C).
6 bar safety unit with pressure gauge ø50 mm 0-10 bar with 3/4” male connection to expansion vessel. End of drain side: 3/4”F.
