16.2 Hot water
The heat pump's hot water production presupposes that
sensor E41.T3 is acknowledged and that heat pump 1 is
set to produce hot water. Heat pump 2 can be set for hot
water production. In the system solutions
( Chapter 8.2.2, 8.2.4), heat pump 1 makes hot water.
In the system solution ( Chapter 8.2.3), heat pump 1
heats hot water and the mixed additional heat afterheats
the hot water. Heat pump 2 is used only for heating
production.
Under Hot water, there are functions to:
• Extra hot water
• Hot water peak
• Hot water program
• Hot water mode
• Hot water settings heat pump x
• Block heating during hot water demand
• Maximum temperature difference circuit 1
• Hot water circulation
• Protective anode installed
• Acknowledge hot water sensor E41.T3
• Acknowledge hot water sensor E42.T3
> Extra hot water
>> Extra hot water duration
B Set the duration of extra hot water production.
>> Extra hot water stop temperature
B Set the stop temperature for extra hot water.
Additional amount of hot water is produced by
temporarily increasing the temperature of the hot water
during the set number of hours to the indicated stop
temperature.
The heat pump starts the function directly and uses the
compressor first and then the additional heat source to
increase the temperature. When the desired number of
hours have passed, the heat pump returns to normal hot
water mode.
> Hot water peak
Hot water peak means a temporary increase in the hot
water temperature to approx. 65 °C for thermal
elimination of bacteria (pasteurisation).
The Hot water circulation pump is controlled by the
control unit during the hot water peak.
For the hot water temperature increase, the compressor
is used first; the additional heat source then continues
alone.
>> Day of the week
B Set the day on which the hot water peak should take
place. None means that the function is disabled. All
means that a hot water peak takes place every day.
>> Interval in weeks
B Set how often a hot water peak should take place.
– 1 means a hot water peak every week.
– 2 means that a hot water peak takes place in all
even weeks of the year, i.e. in week 2, 4, 6, etc.
– 3 means week 3, 6, 9, etc.
– 4 means week 4, 8, 12, etc.
Extra hot water and Hot water peak
require that there is an additional electric
heater in the hot water tank or that the
installation has been configured so that the
mixed additional heat (oil/gas boiler) makes
hot water.
