Technical data
?
When displaying the actual values on the remote control, you
realise that the indicated value does not match the real one. For
example, the actual hot water temperature is 20 °C, but the
display shows 65 °C (or vice versa).
!
An incorrect sensor is connected.
•
Only use sensors with identical characteristic curves.
?
The hot water stays cold during summer mode.
!
Parameter 04 = 03 set (hot water 1 h before heating)
•
Set P04 = 01 or 02.
Should the actions described above fail to help, please
contact your heating engineer.
▷
Please have ready the software version (parameter P13).
