> Heat curve hysteresis heat pump x
>> Maximum
B Set how big the maximum hysteresis from the flow
line can be.
>> Minimum
B Set how big the minimum hysteresis for the flow
temperature can be.
>> Time factor
B Set the time factor that should apply to the hysteresis
reduction. A lower factor gives shorter run times for
the compressor.
Example
With the factory settings, hysteresis is changed, as
follows:
When the flow falls below the set point value with half
the hysteresis, there is heating demand and when it
exceeds the set point value with half the hysteresis, the
heating demand is met.
15.2 Hot water
Under Hot water, there are functions to:
• Acknowledge hot water sensor T3
• 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 operating time for hot water at heating
demand
• Protective anode installed
> Acknowledge hot water sensor 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 first
the compressor and then the additional heat source for
the temperature increase. When the respective number
of hours have passed, the heat pump returns to normal
hot water mode.
