Hi We have a Daikin Heat-pump (EBLA14DA3W1) installed. For air to water heat conversion and distribution of the heated water through a number of internal wall based radiators to our different rooms. We have one issue - Error code 7H-06 - appearing quite often and stopping the heat pump to operate. Have you any information whats this error code means? ...or where I can find more detailed information of the root cause. I would appreciate your feed back very much.

Error code 7H-06 for the Daikin Heat Pump (EBLA14DA3W1) indicates a "Water flow problem during cooling/defrost." This means there is an abnormality in the water flow while the unit is operating in cooling or defrost mode.
