B Indicate Yes in all system solutions Chapter 8.2).
In system solution 8.2.3, there is no physical electric
additional heat in the hot water tanks but the mixed
additional heat provides hot water, extra hot water
and hot water peak. In the event of No, the Extra hot
water and Hot water peak menus are not displayed
and this is why Yes should be selected.
> Temperature change
B Set how much higher the T3 start temperature should
be when hot water is produced with the hot water
electric heater.
When the compressor produces hot water, the
temperature in the heater becomes higher. This is
compensated with this setting.
> Hysteresis
B Set hysteresis for the hot water production.
Additional heat program
This function can be used to set the times between
which additional heat mode is blocked.

B Set a suitable temperature for deactivation of time
control. -26 °C = function Off.
If T2 is over set Outdoor temperature limit for
deactivation of time control for 15 minutes, or if
Outdoor temperature limit for deactivation of time
control is set to Off, the additional heat will be blocked
by time control as long as Additional heat program is
activated.
If T2 is under set Outdoor temperature limit for
deactivation of time control or if Additional heat
program is deactivated the additional heat will not be
