HYSTERESIS
The information below tells you how your heat pump works, there are no values that you as a
customer have to set.
In order to start the heat in advance during sudden changes of the heat demand, there is a
value, HYSTERESIS, which controls the difference between the actual supply temperature, t1
and the calculated supply temperature, t2. If the difference is the same or greater than the
set HYSTERESIS value (x), that is, there is a heat demand, or the heat demand disappears,
quicker than the usual integral calculation, the integral value is forced to either the start value
INTEGRAL A1 or to the stop value 0°min.
Figure 8: Conditions for HYSTERESIS to force the integral value to change.
