R32 Split series – Domestic hot water tank
4P680075-1C – 2022.03
8.3 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 the DHW tank
Powerful operation. However,
this consumes extra energy. See
"5.6.4Using DHW powerful
operation"[49].
If the problems recurs 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 "5.7 Schedule screen:
Example"[410].
The desired DHWtank
temperature is too low.
The thermal cut-out has tripped. Contact your installer.
8.4 Symptom: Heat pump failure
When the heat pump fails to operate, the 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, the booster heater in the tank automatically takes over the
domestic hot water production.
▪ When Emergency is set to Manual and a heat pump failure
occurs, the domestic hot water heating stops.
To manually recover it via the user interface, go to the
Malfunctioning main menu screen and confirm whether the
booster heater can take over the heat load or not.
When the heat pump fails, or will appear on the user
interface.
Possible cause Corrective action
Heat pump is damaged. See "8.1To display the help text
in case of a malfunction"[414].
INFORMATION
When the booster heater takes over the heat load,
electricity consumption will be considerably higher.
