In most cases, the main product notes a malfunction (a
malfunction can lead to disturbance in comfort) and in-
dicates this with alarms and shows action instructions
in the display.
Info-menu
All the measurement values are gathered under menu
3.1 in the main product's menu system. Looking through
the values in this menu can often simplify finding the
source of the fault. See help menu or the main product's
user manual for more information about menu 3.1.

alarm
In the event of an alarm,
some kind of malfunction
has occurred, which is indic-
ated by the status lamp
changing from green con-
tinuously to red continu-
ously. In addition, an alarm
bell appears in the informa-
tion window.
ALARM
In the event of an alarm with a red status lamp, a mal-
function has occurred that the main product 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
main product in 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 most cases it is enough to select "reset
alarm" to correct the problem that caused the alarm. If
a green light illuminates after selecting "reset alarm" the
alarm has been remedied. If a red light is still visible and
a menu called ”alarm” is visible in the display, the
problem that caused the alarm remains. If the alarm
disappears and then returns, see the troubleshooting
section (
page 18 ).
aid mode ”aid mode” is a type of emergency mode.
This means that the heat pump produces heat and/or
hot water despite there being some kind of problem
with the heat pump. This can mean that the heat pump's
compressor is not running. In this case the immersion
heater produces heat and/or hot water.
Problems with ERS 10 do not affect the main product's
operation. You therefore do not need to select ”aid
mode" in event of problems with ERS 10.
Caution
Selecting "aid mode” is not the same as cor-
recting 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 possible fault sources:
• That the main product is running and that the supply
cable to ERS 10 is connected.
• Group and main fuses of the accommodation.
• The property's earth circuit breaker.
• The main product's fuses/temperature limiter.
HIGH OR LOW ROOM TEMPERATURE
• See Installer Manual for the main product.
LOW OR A LACK OF VENTILATION
• Filter blocked.
– Clean or replace the filter.
• The ventilation is not adjusted.
– Order/implement ventilation adjustment.
• Closed, too much choke or blocked ventilation device.
– Check and clean the exhaust air devices.
• Fan speed in reduced mode.
