The "Restratification" function can be activated/deactivated.
No
There will be no restratification with the mixing pump.
Nevertheless, restratification can be activated during the time the "Legionella"
function is active.
Yes
The "Restratification" function compares the 2 DHW storage tank sensors B3 and
B31.
For the "Restratification" function to be performed, storage tank sensor B31 at the
bottom must have reached the set level.
When the temperature at sensor B31 at the bottom of the storage tank exceeds the
temperature at sensor B3 at the top by more than the adjustable restratification
temperature differential (line 5167), mixing pump Q35 is put into operation. The
switching differential is 2 K.
