2.3 Installation
Item 2.3.1. must be read before starting installation.
2.3.1 Dipswitch-setting
The dipswitch-setting (Fig. 6-C), requirements must
be made before starting installation.
Factory setting: All OFF.
2.4 Commissioning
EBC 11 must be commissioned in order to obtain the
correct chimney draught.
Please ensure following:
1. Set the potentiometer 1 and 2 to its maximum set-
ting. (Fig. 6-A and 6-B).
2. Set the pressure differential switch (PDS) at mini-
mum. The PDS is typically placed inside the chimney
fan.
3. Start the system on step 1, boiler thermostat 1 (Fig.
6-F lights up).
4. Wait until the PDS is connected (Fig 6-D lights up).
5. Adjust potentiometer 1 (Fig. 6-A) slowly down to
the correct draught. If the fail-safe system indicates
failure, increase the fan speed at the potentiometer 1.
6. Increase slowly the PDS-setting until disengage-
ment of the PDS can be registered (click sound) or
the light (Fig. 6-D) goes out. Register the PDS-value
of disengagement. Set the PDS to 25 Pa below the
registered value of disengagement.
7. 2-step systems. Start step 2 on the system and
adjust potentiometer 2 (Fig. 6-B) slowly down to the
correct draught. Boiler thermostat 1 and 2 must be
connected (Fig. 6-E and Fig. 6-F lights up). If the fail-
safe system indicates failure, increase the fan speed
at the potentiometer 2.
8. Check that the fail-safe system disconnects the
boiler. Failure can be simulated by disassembling the
minus tube on the pressure differential switch or dis-
connect 18 during operation.
9. Check the start-up function after commissioning is
finished.
