13.11 Connecting auxiliary boiler
The controller can control auxiliary gas or oil burner operation.
The auxiliary boiler is enabled automatically in the event of the main boiler
alarm that prevents its operation or if the temperature in the main boiler
decreases. The auxiliary boiler, e.g. gas boiler must be connected by a qualified
installer in accordance with the boiler documentation. The auxiliary boiler
should be connected via a relay to the terminals 46-47.
