Hi,

on Ecodan I changed from weather compensation curve heating to auto adaptive “room temperature” heating (which uses build-in temperature sensor in my main unit). Room temperature was 22 degrees, outside 7 degrees.

 

After 30 minutes I noticed that electric heater icon was ON (which never happened in weather compensation heating). 

Any suggestions why in auto adaptive heating, electric heater is used?

It could be that the auto adaption could not get the water temperature up high enough so kicked in the electric heater

There may be some useful info in here

Or one of the regular posters with a heatpump may be able to help

Hey @Bosi445 

 

Jeffus has given some good advice above and tagged a few of our heat pump regulars, so hopefully someone might have some helpful insight here.

 

We’ve also got a couple of other topics on the Ecodan curve settings that may potentially be helpful to you:
