Adjusting the  type of installation

The boiler is designed in such a way that it will 

adjust  itself  automatically  to  what  is  necessary 

for a normal heating system. In some cases the 

installation may have convectors or complete un-

derfloor heating. 

One can easily choose heating installation adjust-

ments appropriate for the system such as maxi-

mum water-flow temperature or for the warming up 

of the installation after a night period. Adjustment 

goes as follows:

-  Press (from the Technical) reading the Mode 

key once;

-  Press the Step key twice;

 

The display will show  

2  01.

-  Press  the  +  or  the  -  key  to  alter  the  type  of 

installation according to the table below;

-  Press the Store key to confirm the setting;

  The display will flash once.

-  Press the Mode key once;

 

The display will show 

StbY  for a short while 

and will return to the Technical reading.

When a type of installation has been chosen with a low water-flow  temperature it 

is possible that in case of a severe winter period the temperature of the heating 

system will need to be increased slightly. In such situations the installation choice 

may need to be changed, so that a higher flow temperature can be chosen. This 

adjustment would normally be carried out by your installer during the installation 

and commissioning.
