Daikin hybrid for multi heat pump – heat pump module
4P471761-1A – 2017.10
13.3.16 Symptom: The power is reduced
Possible causes Corrective action
At high rpm, the power has fallen
by more than 5%.
▪ Check the appliance and flue
system for fouling.
▪ Clean the appliance and flue
system.
13.3.17 Symptom: Space heating does NOT reach
the temperature
Possible causes Corrective action
Weather-dependent setpoint
setting is incorrect.
Check the setting on the user
interface and adjust if necessary.
Temperature is too low. Increase the space heating
temperature.
No circulation in the installation. Check whether there is
circulation. At least 2 or 3
radiators MUST be open.
The boiler power has NOT been
correctly set for the installation.
Adjust the power. See "Maximum
space heating power setting"on
page65.
No heat transfer as a result of
lime scale or fouling in the heat
exchanger.
Descale or flush the heat
exchanger on the space heating
side.
13.3.18 Symptom: Hot water does NOT reach the
temperature (no tank installed)
Not applicable for Switzerland
Possible causes Corrective action
Domestic hot water flow is too
high.
Adjust the inlet assembly.
Temperature setting for water
circuit is too low.
Increase the domestic hot water
setpoint on the domestic hot
water homepage of the user
interface.
No heat transfer as a result of
lime scale or fouling in the heat
exchanger domestic hot water
side.
Descale or flush the exchanger
domestic hot water side.
Cold water temperature <10°C. The water inlet temperature is
too low.
The domestic hot water
temperature fluctuates between
hot and cold.
▪ The flow is too low. To
guarantee comfort, a minimum
water flow of 5 l/min is
recommended.
▪ Increase the domestic hot
water setpoint on the domestic
hot water homepage of the
user interface.
13.3.19 Symptom: Hot water does NOT reach the
temperature (tank installed)
Possible causes Corrective action
The gas boiler has an error code. Check the display of the gas
boiler for more information.
The indoor unit has an error
code.
Check for possible errors on the
indoor unit.
Possible causes Corrective action
The 3-way valve is not working
correctly.
▪ Check the installation of the 3-
way valve.
▪ In case of domestic hot water
operation, the flow should be
directed to the tank.
13.4 Solving problems based on error
codes
When a problem happens, an error code appears on the user
interface. It is important to understand the problem and to take
countermeasure before resetting the error code. This should be
done by a licensed installer or by your local dealer.
This chapter gives you an overview of all error codes and the
content of the error code as it appears on the user interface.
For a more detailed troubleshooting guideline for each error, please
see the service manual.
13.4.1 Error codes: Overview
Error codes of the indoor unit
Error code Detailed error
code
Description
7H 01 Water flow problem.
7H 04 Water flow problem during
domestic hot water production.
Manual reset.
Check the domestic hot water
circuit.
7H 05 Water flow problem during
heating/sampling.
Manual reset.
Check the space heating/cooling
circuit.
7H 06 Water flow problem during
cooling/defrost.
Manual reset.
Check the plate heat exchanger.
80 00 Returning water temperature
sensor problem.
Please contact your dealer.
81 05 Loosehanging tank
temperature sensor
81 00 Leaving water temperature
sensor problem.
Please contact your dealer.
81 04 Leaving water temperature
sensor not properly mounted.
89 01 Heat exchanger frozen.
