DomvS Circ 2

RECIRCULATION KIT FOR DOMESTIC HOT WATER TANK

The kit allows make easily the connections between the DHW circulation system and a domestic hot water tank. The pre-assembled and insulated kit, by means of an anti-scald thermostatic mixer, allows the user to set hot water temperature from 35 to 60°C. The temperature of the recirculation line is adjusted independently by a dedicated thermostat integrated in the high-efficiency circulating pump, while a special metal back plate facilitates installation both on the wall and on hot water tank.
Suitable for medium-sized users up to 82 L/min. (1.5 bar).

Features
• Anti scald thermostatic mixing valve.
• Control of user temperature adjustable by means of a knob from 35°C up to 60°C.
• The check valves and the isolating valves in the kit do not require the installation of any other hydraulic control component.
• Thermometers with scale 0÷120°C display the temperature of the hot water in the tank, mixed water for user and recirculation line.
• High efficiency circulating pump for the recirculation line with temperature sensor to restrict the working time, keeping the water into the piping at the required temperature. The pump automatically stops when the water temperature reaches the set value on the body of the motor (between 20 and 70°C).
• Version with circulating pump equipped with thermostat and timer for a better energy saving.
• Back plate to fit the kit to the wall or to the water tank.

Technical features
• Maximum static pressure 10 bar (PN10); dynamic 5 bar.
• Maximum ratio between pressures 2:1.
• Maximum inlet temperature of the thermostatic mixing valve: 95°C.
• User setting temperature range: 35÷60°C.
• Accuracy: ±2°C.

Connections:
• 3/4”Female.
