Enabling emergency operation for heating or DHW (Emergen. mode)
If the compatible Aermec accessory tank for this mod-
el (refer to the installation manual for more informa-
tion) - and/or an additional heat source (paragraph
7.7) or electric heater (paragraph 7.8) - is installed and
correctly set on the system, you can enable the “Emer-
gency mode” function which excludes the heat pump
for hot water (domestic or system) production, using
only the electric heater of the storage tank and/or the
additional heat source (or electric heater) to meet the
requests. After accessing the “Emergen. mode” func-
tion, you can enable or disable this program; you must
then press “OK” to confirm.
