Malfunctions

Malfunction

Possible cause

Possible solution

System not working (no
display)

No mains voltage

●

Switch on the external main switch of the machine.

●

Switch on system fuse(s).

●

Replace system fuse(s).

Switching time program
is not working or pro-
grammed switching times
are being carried out at
the wrong time.

Date and time are not correctly set.

●

Set date.

●

Set time.

●

Check week day-switching time allocation.

Incorrect operating mode set.

●

Set to operating mode "Automatic 1" or "Automatic 2".

During a switching time the user made a man-
ual setting (e.g. changed the target tempera-
ture, changed the operating mode)

1. Place the rotary switch in the

"Info"

position.

2. Place the rotary switch in the

"Operating Mode"

position.

3. Select correct operating mode.

Control unit does not
respond to entries

Operating system of control unit crashed.

●

Carry out RESET of control unit. o do so, disconnect
the system from the power supply for at least 10 s and
then switch on again.

Operating data are not
updated

Operating system of control unit crashed.

●

Carry out RESET of control unit. To do so, disconnect
the system from the power supply for at least 10 s and
then switch on again.

●

Have the heating system checked by a Daikin heating
technician.

Heating does not warm
up

Heating request switched off (e.g. switching
time program is in the economy phase, exter-
nal temperature is too high, parameters for
backup heater (EKBUxx) are set incorrectly,
hot water request is active)

●

Check the operating mode setting.

●

Check the request parameters.

●

Check setting of the date, time and switching time
program on the control unit.

Refrigerant compressor is not working.

●

Have the heating system checked by a Daikin heating
technician.

System is in the operating mode "Cool-

ing".

●

Switch the operating mode to "Heating".

Settings for off-peak mains connection do not
correspond to settings for electrical connec-
tions.

●

Have the heating system checked by a Daikin heating
technician.

The power company has sent the high-cost
signal.

●

Wait for the repeat off-peak rate signal which reacti-
vates the power supply.
