ERROR
The ERROR report appears when the heat pump is switched off via a
safety device / safe-
ty function.
In ERROR cases, the system changes to "emergency operation - reduced". The
system is controlled at reduced temperatures (heating and warm water) and the addi-
tional heat generators (electro auxiliary, furnace) take over the heating (if installed).
Emergency mode economy
: The set value for heating will be reduced by 7°C; the set val-
ue for hot water to 35°C.
NOTE
The heat pump restarts automatically when the safety device releases the heat pump (er-
ror no longer in system).
Following malfunction repair measures are possible:

Automatic acknowledgement
3
Manual acknowledgement
The manual acknowledgement only leads to a heat pump restart when the error is
no
longer
present at the safety device.

er present after acknowledgement, the heat pump restarts and the additional heat gen-
erators turn off.
Example of error acknowledgement:

Remedying the ERROR reports may only be carried out by OCHSNER authorised
installers! Before beginning work on the heat pump, it must be switched off on

rect changes to settings by third parties will delete all warranty and guarantee
claims.
