INFORMATION
In case of error code AH and no interruption of the
disinfection function occurred due to domestic hot water
tapping, following actions are recommended:
▪ When the Domestic hot water > Type > Reheat or
Reheat + sched. is selected, it is recommended to
program the start-up of the disinfection function at least
4 hours later than the last expected large hot water
tapping. This start-up can be set by installer settings
(disinfection function).
▪ When the Domestic hot water > Type > Scheduled only
is selected, it is recommended to program a Storage
eco 3 hours before the scheduled start-up of the
disinfection function to preheat the tank.
NOTICE
When the minimum water flow is lower than described in
the table below, the unit will temporarily stop operation and
the user interface will display error 7H‑01. After some time,
this error will reset automatically and the unit will resume
operation.
If the 7H‑01 error persists, the unit will stop operation and the user
interface will display an error code that needs to be reset manually.
Depending on the problem, this error code is different:
Error code Detailed error
code Description
7H 04 The water flow problems mainly
occurred during domestic hot
water operation. Check the
domestic hot water circuit.
7H 05 The water flow problems mainly
occurred during space heating
operation. Check the space
heating circuit.
7H 06 The water flow problems mainly
occurred during cooling/defrost
operation. Check the space
heating/cooling circuit.
Additionally, this error code might
be an indication of frost damage
to the plate heat exchanger. In
that case, contact your local
dealer.
INFORMATION
Error AJ-03 is reset automatically from the moment there is
a normal tank heat-up.
INFORMATION
Error EC-04 is reset automatically from the moment the
domestic hot water tank is preheated to a sufficiently high
temperature.
INFORMATION
If the unit detects flow when the pump is not running, an
external device might be causing flow, or there might be
something wrong with the flow measuring devices (flow
sensor and flow switch).
▪ If the flow sensor detects flow when the pump is not
running, the unit will stop operation and the user
interface will display error C0‑00. For the unit to resume
operation, this error needs to be reset manually.
▪ If the flow switch detects flow when the pump is not
running, the unit will temporarily stop operation and the
user interface will display error C0‑01. After some time,
the error will reset automatically and the unit will
resume operation. If the problem persists, the unit will
stop operation and the user interface will display error
C0‑02. For the unit to resume operation, this error
needs to be reset manually.
