The set temperature of tank no. 2 is determined by parameter B.02 DHW TANK 2 SET
TEMPERATURE. Hysteresis for the set temperature is 2K.
Parameter D.10 T3-T4 DELTA FOR P2 PUMP ON determines T3-T4 delta for
activating P2 pump.
Parameter D.11 T3-T4 DELTA FOR P2 PUMP OFF determines T3-T4 delta for
stopping P2 pump.
Holiday mode does not affect heat transfer.
