CHAPTER 4. COMMISSIONING 

 

4.1. Electrical connection 230 VAC 

• 

If the boiler is provided with a 

supply cord and a plug

 

the appliance must be positioned so that the plug is 
accessible. 

• 

If the boiler is not provided with a 

supply cord without 

a plug

 the supply must have a contact separation of at 

least 3 mm in all poles. 

If the supply cord is damaged, it must be replaced by the 
service agent or similarly person in order to avoid a hazard. 
 

4.2. Main switch 

 
To power up the appliance 
please switch the main 
switch on. 
 
If the display of the unit gives 
the status code ‘U’ 
(alternately with an arbitrary 
other code), this means the 

live and neutral  
connections are reversed. Isolate the supply and reverse 
the connections. 
 

4.3. Filling 

During filling with water, the unit must be connected to the 
mains and be switched on. Fully open all radiator taps. 
Connect the water supply to the filling connection. If the 
unit is not yet filled with water, the display shows a flashing 
‘P’. The two numbers on the display give the water 
pressure. 
Open the tap to fill the system with water. 
When the water pressure is sufficient (> 1.3 bar), the 
flashing ‘P’ disappears from the display. 
Close, after filling, the filling tap again. 
 

4.4. Reading the water pressure 

It is possible to read the water pressure directly from the 
display. To do this, press the + button of the display for a 
minimum of 5 seconds. 

 
The unit switches out of the menu back to normal 
operation: 

• 

automatically after about 5 minutes; 

• 

or if you press the - button of the display shortly. 

 

4.5. Venting 

After filling, the heating installation must be vented.  
 

Proceed as follows: 
Follow the instructions from the manufacturer/installer for 
the venting of possible other elements of the heating 
installation, such as underfloor heating. 
Fully open all radiator taps. 
Open the air bleed cocks of the radiators one at a time. 
Use an air bleed key for this. 
As soon as water comes out of the air bleed cock, shut the 
cock off again. 
 

 

4.6. Chimney sweeper function 

The chimney sweeper function has priority over the central 
heating and HWS regulation. 

 
 
The chimney sweeper 
function is activated by 
simultaneously pressing the 
"+ and the – buttons" of the 
display in for longer than 5 
seconds. 
 

 
The ionisation current can be read in microamperes in the 
two right segments. 
 
The capacity that is immediately released is the maximum 
central heating capacity. 
 

 
 
 
 

   Press the "- button" to 

go to low load. 
 
 
 
 
 

   Press the "+ button" 

to switch back to the preset 
full load capacity. 
 
 

 

4.7. Gas / Air Ratio 

 
(1).

 Venturi screw 

– Full load adjustment

 

Turn the venturi screw anti-clockwise to increase the CO

2

 

value, clockwise to decrease it. 
(2).

 Gas control screw 

– Low load adjustment

 

Turn the screw anti-clockwise to decrease the CO

2

 value 

on low load, clockwise to increase it. 
(3). Cover screw
