Disturbances in comfort

In most cases, F370 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 heat pump measurement values are gathered under
menu 3.1 in the heat pump menu system. Looking through
the values in this menu can often simplify finding the source
of the fault. See help menu or user manual for more inform-
ation about menu 3.1.

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 heat pump 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 heat pump 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 heat pump 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 running. 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:
BASIC ACTIONS
Start by checking the following items:
• The switch's (SF1) position.
• Group and main fuses of the accommodation.
• The property's earth circuit breaker.
• The heat pump's RCD.
• Miniature circuit breaker for F370 (FC1).
• Temperature limiter for F370 (FQ10).
• Correctly set load monitor.
LOW HOT WATER TEMPERATURE OR A LACK OF
HOT WATER
• Closed or throttled externally mounted filling valve for the
hot water.
– Open the valve.
• F370 in incorrect operating mode.
– Enter menu 4.2. If mode "auto" is selected, select a
higher value on "stop additional heat" in menu 4.9.2.
– If mode "manual" is selected, select "addition".
• Large hot water consumption.
– Wait until the hot water has heated up. Temporarily in-
creased hot water capacity (temporary lux) can be ac-
tivated in menu 2.1.
• Too low hot water setting.
– Enter menu 2.2 and select a higher comfort mode.
LOW ROOM TEMPERATURE
• Closed thermostats in several rooms.
– Set the thermostats to max, in as many rooms as pos-
sible. Adjust the room temperature via menu 1.1, instead
of choking the thermostats.
See the "Saving tips" section in the User manual for
more detailed information about how to best set the
thermostats.
• F370 in incorrect operating mode.
– Enter menu 4.2. If mode "auto" is selected, select a
higher value on "stop heating" in menu 4.9.2.
