Commissioning
Commissioning on the EBC20 must be carried out to ensure a correct draft from the system.
Commissioning should be carried out by staff with the appropriate training, and with the authorisation to do
so according to local legislation.
Do as follows:
Step
Action...
1
Provisional draft setting (negative pressure):
• Press
OK
to go to Menu 1
• Press
OK
• Press
or
until the negative required pressure appears in the display
• Press
OK
to confirm and save the set point
• Press
RESET
to return to the operation screen
2
• Start the system
• Wait until the boiler starts and the draft has stabilised. The current draft will be shown in the display
3
Final adjustment of draft:
• Check the draft on the boiler
• If draft is not correct, repeat the procedure from step 1
4
Check that the monitoring system shuts off the boiler
To simulate an error situation, disconnect the hose from the pressure transducer (XTP). Burner is switched
off (diode switches off) and the alarm diode illuminates
5
After completing the commissioning, check the start-up function by restarting the system
For the set point values, please refer to the data for the boiler in question. However, the following values can be
considered typical:
• Boilers with forced draft: typically 20–30 Pa
• Boilers with atmospheric burners: typically 5–10 Pa
Set up according to site conditions can be determined by boiler commisioning engineer.

Special functions
2.8.1
Start/stop through temperature sensor on the fume output
The control can start and stop the fan automatically with the temperature sensor. 2.4.6 Solid fuel boiler with
temperature sensor, page 22.
2.8.2
Boiler controlled process
With boiler controlled process you can activate the possibility for forced pre run/post run or activate the running of the
fan during a break in the boiler heating. You can regulate the speed of the fan from 35% to 100%.
• Connect the boiler thermostat as diagram one boiler, on terminal 11+12 ( Boiler 2)
• For instance connect the signal from the internal cooler in the boiler to terminal 15+16 (boiler 2)
• Set menu 361 in the service menu to ON
• Set the speed in menu 362 between 35% and 100%
• Set the priority input in the menu 363. When choosing ON, first priority input is Boiler 1, terminal 11+12.
When choosing OFF, first priority is Boiler 2, terminal 15+16.
