Hello guys,

I have a problem with Altherma setting, maybe someone could help me out.
I have a hxydrobox EHVH16S26C9W and outdoor unit 11 kW. Unit is 1 year old.

My target tank temperature is 46 degrees. Setting for tank is reheat and scheduled.
I noticed when temperature falls for 3 degrees - pump starts and backup heaters jump in. In summer if I m lucky in morning outdoor unit starts, but during the day it just heats up with backup heaters.

How can I modify heat pump that it would heat up water with outdoor unit at desired temperature difference and is there any time blockage that I would not get 50 starts in day just for hot water.
