[6] - Hysteresis (DT) for water heating
The parameter settings [6-XX] determine the temperature limits at which heating the hot water is started and stopped by the
heat pump (ON temperature and OFF temperature of the heat pump).
If the water temperature falls below the ON temperature of the heat pump (T
HP ON
), heating the hot water with the heat pump
is started.
As soon as the hot water temperature reaches the OFF temperature of the heat pump (T
HP OFF
) or the user target temperature
(TU), heating the water with the heat pump is stopped (the switch unit switches to room heating or the heat pump stops heating).
The following setting options are available:
– [6-00] Start: Temperature difference that determines the ON temperature of the heat pump (T
HP ON
).
– [6-01] Stop: Temperature difference that determines the OFF temperature of the heat pump (T
HP OFF
).
