8.2.1 Heat pump only
The HP unit is activated to produce DHW, if the DHW tank temperature falls below the value set for parameter
“Economy DHW set point – DHW hysteresis” or “Comfort DHW set point – DHW hysteresis”.
HP unit stops DHW production:
A) When the DHW tank temperature reached to DHW set point.
B) When Outgoing water temperature reaches to the maximum set temperature, according to the operating
limits of HP unit.
