(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.
