Commissioning
Commissioning must be carried out on the EBC20 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
Setting chimney fan stage 1 (LOW)
• Press
OK
to go to Menu 1.
• Press
OK
• Press
or
to set the “LOW” value to max (100%).
• Press
OK
to confirm and save the set point.
• Press
RESET
to return to the operation screen.
2
• Start the system on stage 1.
3
• Wait until the PDS is connected (PDS diode lights green).
4
• Access menu 1 as described in step 1.
• Slowly adjust “LOW” to the correct draft.
• If the PDS shows an error (the alarm diode and
flashes), adjust the setting of
the PDS.
5
Only for 2-stage systems:
• Start the system on stage 2.
• Access menu 2 and slowly adjust “HIGH” to the correct draft.
• Both boiler thermostats 1 and 2 must be connected (the BOILER 1 IN and BOILER 2
IN diodes light green).
6
Check that the monitoring system shuts down the boiler. If necessary, you can
simulate an error condition by disconnecting the hose from the negative terminal on
the PDS.
7
After completing the commissioning, check the start-up function.
Refer to the boiler manufacturer’s technical data for relevant pressure requirements and adjust the %-values
accordingly. However the following value can be considered typical:
• Boilers with atmospheric burners: typically 5–10 Pa.
