Description
Compact unit that allows the best management of hot water coming from the solar panel for the sanitary system.
In the event of a low temperature of the water from the solar panel, the unit activates the boiler for integration, so as to always send the user hot water at the desired temperature.
If the temperature is too high or if there is a lack of cold water at the inlet, the unit immediately closes the hot water passage to avoid dangerous burns.
The water coming from the solar panel is diverted towards the boiler or the sanitary network depending on whether its temperature (t1) is lower or higher than 60 °C: this value can be changed (ex. to 50 °C) by operating on the electronic control unit menu.
By turning the knob on the thermostatic mixer, the outlet temperature of domestic hot water is adjusted to the desired value.
Once set, it is possible to lock the mixer by turning the grub screw on the knob, preventing accidental manipulations.
