eAux

Selects the source used to control the set-point temperature.

External

means that the set-point will be determined by the auxiliary

boiler. The VOLTMAX boiler therefore has no set-point temperature and is
used only to activate the auxiliary boiler’s relay.

Internal

means that the set-point temperature will be determined by the

VOLTMAX boiler.
