Optical sensor connection
The optical sensor should be connected in
accordance with point 12.5, be sure to
observe the polarization of the (+) and (-)
sensor signals. Readings of data from optical
sensor is possible in the menu:
Information

Flame
Incorrect connection of the optical
sensor
will
not
damage
the
controller or the sensor itself, but
the burner flame detection will be
incorrect.

Connection of reserve boiler
The controller can control a reserve boiler
(gas- or oil-fired), eliminating the necessity
of enabling or disabling this boiler manually.
Connection to a reserve boiler, e.g. oil-fired
one, should only be made by a qualified
fitter, in accordance with the technical
documentation of this boiler. The reserve
boiler
should
be
connected
via
relay to terminals 30-31 additional B module.
An example of a reserve boiler connection scheme: 1
–
additional B module, 2
–
reserve boiler (gas- or oil-), 3
–
relay 6 VDC
.
Standard version of the controller is not
equipped with a relay.
Assembly of relay should be
done by a person with proper
qualifications. According to valid
norms and regulations.
To enable the control of reserve boiler, set
the H output (mod B) to operate the
Reserve
boiler
in the menu:
