When 'on' the indication L.E.D. is illuminated.
In most situations the pump can stay in position 'off'.
During severe frost It is possible (when there is no outside
sensor connected), to choose manually to let the circulation
pump circulate continually thus reducing the chance of
freezing pipes (garage, attic or other cold spaces / rooms)
which are sensitive to frost.
Explanation of the function keys and display
When the pump is switched
on continuously it can lead
to undesired heating up of
the central heating system
during the summer.

Indication L.E.D.'s
On the left side of the boiler there is a small door.
Through the transparent part you can see the boiler
status on the display. After opening this door you will
find the function keys. On the right side of the door
you will find an instruction card in a sleeve with an
explanation of the display messages and function
keys. This is described below.

The boiler will not function directly. The automatic de-aeration programm of
about 17 minutes will start after one of the three programm keys is pressed.
The display will show
where A stand's for Automatic de-aeration
programm Active and the number on the right indicates the actual water
temperature of the boiler.
Check the water pressure regularly and top up the installation when necessary.
The working pressure of the installation should be between 1.5 and 1.7 bar
It can take a while before all air has dis-appeared from a filled installation.
Especially in the first week noises can be heard which indicate the presence
of air. The automatic air vent in the boiler will make this air disappear, which
means the water pressure will reduce during this period and therefore topping
up with water will be necessary to adjust the flow water temperature
