Hi there,

I have a Daikin Altherma 3 H HT installed last year with a buffer tank which means the Daikin is mainly working on the living temperature based on the weather curve as it does not have a thermostat connected to it. 

There is an option to use “modulation mode” which gives the Daikin the possibility to fine tune its leaving water based on the indor temperature and the target temperature. To use this option though I would need to remove/bypass the water tank/circulator and get a thermostat connected to the Daikin.

My naive view is that running modulation mode allows to take advantage of the inverter technology and have the Daikin automatically running all the time at a minimum power and get closer to the objective of having the heat pump just constantly compensating for the heat loss.

Are there people on the community using the modulation mode on their Daikin?

I would be happy to get some feedback on how it works.

Many thanks and sorry for this cancid and naive question.

Regards,

Antoine
