Pressurized Solar System Installation with Single Serpentine Boiler:
Applicable Combi Boiler Model:
Confeo Premix HM Models
Mode of Operation:
The boiler domestic water line inlet is directly connected to the boiler. The
boiler’s mainboard manages the PT 1000 sensor and the Solar pump connected to it. It is
connected to the terminal “C” (Boiler Sensor – HONEYW.T7106A10 – 7006952618) that reads “solar”
on the back of the control panel of the boiler. The hot water need up to 40 °C is met directly from the
boiler and the boiler does not run.
In case of a hot water need above 40 °C, the combi boiler runs and provides support to reach the
set temperature. The water in the boiler is used as the domestic water flowing directly from the tap.
Necessary Parameter Changes:
The P00 parameter is set to “2” and the “HM+Solar"
configuration is activated.
