Daikin Europe NV
47
No
No electrical supply (24 V). Yes
Replace the faulty
controller
. Check the wiring in accordance with the diagram.
Check the connector X4.
Replace the faulty
controller
.
8.2.4 The power is reduced
Possible causes:
Solution:
At high rpm, the power has decreased. Yes
Clean the unit and siphon.
Check the flue tube and the air supply system.
8.2.5 CH is not reaching correct temperature
Possible causes:
Solution:
Water pressure in installation is too low.
Yes
Top up the installation. See par. 6.1.1.
No
Room thermostat is not set correctly.
Yes
Check the setting and adjust if required.
No
Temperature is set too low. Yes
Increase the CH temperature See Operation CH. If there is an
outdoor
sensor:
Check the outdoor sensor for short circuit: rectify this.
No
No flow through the installation. Yes
Check the ∆T (± 20° C) between the supply and
return CH. Ensure there is good
flow through the installation.
No
The boiler power is not set correctly.
Yes
Adjust the boiler power. See Setting maximum CH power.
No
No heat transfer due to contamination in the CH
boiler/installation.
Yes Rinse the CH boiler/installation on the side of the CH.
8.2.6 No domestic hot water
Possible causes:
Solution:
The service display shows nothing.
Yes
Check whether the plug is in the socket.
No
The service display shows nothing.
Yes
Check the
fuse, see Electrical diagram par. 10.1
No
Flow sensor does not work.
Yes
Replace the flow sensor.
No
Tap flow <
1
.
5
l/min.
Yes
Increase the tap flow.
No
No electricity supply on flow sensor (5V DC).
Yes
Check the wiring in
accordance with the diagram.
No
S3 faulty.
Yes
Replace S3.
No
The thermostatic shower or bath tap is faulty. Yes
The thermostatic tap only lets through cold water. This means the tap flow through
the boiler remains under 1.5 l/min. Check the thermostatic tap.
8.2.7 DHW is not reaching the correct temperature
Possible causes:
Solution:
Tap flow too high. Yes
Reduce the tap flow. Check the dosing disk (EKOMBG22AAV1 and
EKOMBG28AAV1)
No
DHW
temperature set too low.
Yes
Increase the
DHW
temperature, see par. 7.1.
CH installation becomes hot during tapping. Yes
Unwanted circulation in the ch circuit during hot water request due to thermosiphon
effect or second pump in the CH circuit. Install a check valve in case of
thermosiphon effect or a two-way valve in case of a second pump.
No
Insufficient heat transfer due to lime scale or
Yes
Remove lime scale or rinse the CH boiler on the tap water side.
