8.4 Symptom: The water at the tap is
too cold
Possible cause Corrective action
You ran out of domestic hot
water because of unusually high
consumption.
If you immediately need domestic
hot water, activate:
▪ [4.1] Powerful operation.
However, this consumes extra
energy. See "5.7.4Using DHW
powerful operation"[412].
▪ [4.3] Manual tank heat-up.
If the problems recur daily, do
one of the following:
▪ Increase the DHW tank
temperature preset value. See
the user reference guide.
▪ Adjust the DHW tank
temperature schedule.
Example: Program to
additionally heat up the
DHW tank to a preset value
(Eco setpoint = lower tank
temperature) during the day.
See "5.8 Schedule screen:
Example"[413].
The desired DHWtank
temperature is too low.
8.5 Symptom: Heat pump failure
When the heat pump fails to operate, the backup heater and/or
booster heater can serve as an emergency heater. It then takes over
the heat load either automatically or by manual interaction.
▪ When Emergency is set to Automatic and a heat pump failure
occurs:
▪ For ETVH/X: The backup heater automatically takes over the
domestic hot water production and space heating.
▪ For ETBH/X: The backup heater automatically takes over the
heat load, and the booster heater in the optional tank takes over
the domestic hot water production.
▪ When Emergency is set to Manual and a heat pump failure
occurs, the domestic hot water heating and space heating stops.
To manually recover it via the user interface, go to the
Malfunctioning main menu screen and confirm whether the
backup heater and/or booster heater can take over the heat load
or not.
▪ 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 and/or booster heater if the user activates this
via the Malfunctioning main menu screen.
When the heat pump fails, or will appear on the user
interface.
Possible cause Corrective action
Heat pump is damaged. See "8.1To display the help text
in case of a malfunction"[416].
8.6 Symptom: The system is making
gurgling noises after
commissioning
Possible cause Corrective action
There is air in the system. Purge air from the system.
(a)
Incorrect hydraulic balance. To be performed by the installer:
1 Perform hydraulic balancing
to assure that the flow is
correctly distributed
between the emitters.
2 If hydraulic balancing is not
sufficient, it is recommended
to increase the Delta T
heating ([1.14] / [2.14])
value.
Various malfunctions.
Check if or is displayed
on the home screen of the user
interface. See "8.1To display the
help text in case of a
malfunction"[416] for more
information about the
malfunction.
(a)
We recommend to purge air with the air purge function of the unit
(to be performed by the installer). If you purge air from the heat
emitters or collectors, mind the following:
WARNING
Air purging heat emitters or collectors. Before you
purge air from heat emitters or collectors, check if or
is displayed on the home screen of the user interface.
▪ If not, you can purge air immediately.
▪ If yes, make sure that the room where you want to
purge air is sufficiently ventilated. Reason: In case of a
breakdown, refrigerant might leak into the water circuit,
and subsequently into the room when you purge air
from the heat emitters or collectors.
9 Disposal
When you want to dispose of the unit, do NOT do it yourself but
contact a Daikin certified technician.
NOTICE
Do NOT try to dismantle the system yourself: dismantling
of the system, treatment of the refrigerant, oil and other
parts MUST comply with applicable legislation. Units
MUST be treated at a specialised treatment facility for
reuse, recycling and recovery.
