In most cases, VVM 310 notes a malfunction (a malfunction
can lead to disruption in comfort) and indicates this with
alarms, and instructions for action, in the display.
Info-menu
All the installation’s measurement values are gathered under
menu 3.1 in the indoor module’s menu system. Examining
the values in this menu can often make it easier to identify
the source of the fault.

alarm
In the event of an alarm, some kind of malfunction has oc-
curred, which is indicated by the status lamp changing from
green continuously to red continuously. In addition, an alarm
bell appears in the information window.
ALARM
In the event of an alarm with a red status lamp, a malfunction
has occurred that the indoor module cannot remedy itself.
By turning the control knob and pressing the OK button, you
can see in the display what type of alarm it is and reset it.
You can also choose to set the indoor module to aid mode.
info / action Here you can read what the alarm means and
receive tips on what you can do to correct the problem that
caused the alarm.
reset alarm In many cases, it is sufficient to select “reset
alarm” for the product to revert to normal operation. If a
green light comes on after selecting “reset alarm”, the alarm
has been remedied. If the red light is still on, and a menu
called “alarm” is visible in the display, the problem causing
the alarm still remains.
aid mode “aid mode” is a type of emergency mode. This
means that the indoor module produces heat and/or hot
water, even though there is some kind of problem. This could
mean that the heat pump’s compressor is not in operation.
In this case, the immersion heater produces heat and/or hot
water.
Caution
To select aid mode an alarm action must be selec-
ted in the menu 5.1.4.
Caution
Selecting "aid mode” is not the same as correcting
the problem that caused the alarm. The status
lamp will therefore continue to be red.
Troubleshooting
If the operational interference is not shown in the display
the following tips can be used:
