4.9 Hot water mode
HOT WATER switched on will enable hot water production. If you should want a prioritization on the amount of hot water and a faster
hot water production you should change mode to either ECO or COMFORT. By activating TOP-UP the heat pump can immediately start
to heat the water heater using the compressor and electrical auxiliary heater until the tank is fully heated. The TOP-UP function has to
be reactivated each time it is needed.

"COMFORT" is the choice for customers with large demands of hot water availability.
▪
"ECO" can be selected as the best compromise between energy efficiency and hot water availability.
▪
"AWAY" is a setting that charges the hot water tank just enough to keeping it maintaining safety functions, like defrost etc. Typical-
ly a setting when you're away on vacation.
Remember to inform the end customer that the settings can be changed in the settings menu
