Minimum flow temperature
Do you know how can I identify what is the minimum flow temperature the boiler can maintain ?
As per its datasheet it can modulate down to 3.5 kW, however I have the feeling that Tado requests too small temperature and what is happening is that the boiler heats the water to 42 Celsius, then turns off the burner and just circulates the water in the system until it is back at 32 Celsius, then repeat. This results that at every 1-2-3 minutes the burner is turned on then off. When the temperature was colder outside it could produce a stable 38 Celsius water.
