the second heating stage will be received. The target
temperature will immediately start increasing.
N.B.
If the system is in “boost” most of the time, this
means that the boiler target parameter established
during “Setting procedure” would be too low for the
heating system on which the unit is applied. This boiler
target could simply be gradually increased by pressing
the + button or by re-setting the operating parameters
using the tool menus
.
The Boost menu can be cancelled by selecting “OFF” in
the Boost menu.

), the following
icons will be shown.
The circulating pump and the heating elements will be
activated according to the operating parameters
established earlier.
Operation
in
automatic
transfer
mode
with
Renewable energy source
When the authorisation signal will be absent (open
contact between
E

), the following icons will be
shown.
Upon reception of a heat demand on terminals
R W
of
the ECO ULTRA boiler, terminals
P
1
&P
2
will be
energized at 120volts and the pump will be activated. At
the same time, the contact will close on the “
AUX”
terminals to activate the auxiliary boiler. This boiler will
be activated only when there will be a heat demand to
the
R W
terminals and when the auxiliary boiler
temperature will be lower than the settings of its own
temperature controls.
Using the
"
AUX
"
terminals on the ECO ULTRA to allow
the start-up of the renewable energy source, you operate
either with the renewable energy source or with
electricity.
It is also possible to allow the renewable energy source
to be operated according to its own controls at all times
(do not use the contact of the "
AUX
" terminals) and when
the latter is not sufficient to the request, (closed contact
between
E1 & E2
) the heating elements will be activated
according to the operating parameters established
previously.
