automatically select the output of the heater required.
Once the room temperature has been reached, the heating
will switch off (regardless of the water temperature).
If the boiler is full of water then it will be heated automatically
at the same time.The water temperature is however
dependent on the seat output of the heater and will switch
off when the room reaches the desired temperature.
In this condition the yellow monitor lamp (g) will only light up
if the water temperature is below 5 °C.
