Alternatively, when
Emergency
is set to:
-
auto SH reduced/DHW on
, space heating is reduced but domestic hot
water is still available.
-
auto SH reduced/DHW off
, space heating is reduced and domestic hot
water is NOT available.
-
auto SH normal/DHW off
, space heating operates as normally but
domestic hot water is NOT available.
Similarly as in
Manual
mode, the unit can take the full load with the backup
heater if the user activates this via the
Malfunctioning
main menu screen.
To keep energy consumption low, we recommend to set
Emergency
to
auto SH
reduced/DHW off
if the house is unattended for longer periods.

Glycol filled system
Glycol Filled system
This setting gives the installer the possibility to indicate whether the system is filled
with glycol or water. This is important in case glycol is used to protect the water
circuit against freezing. If NOT set correctly, the liquid in the piping can freeze.
