*Off-level DHW
ctrl
Deactivation threshold for the domestic hot water control. If the value
falls below this flow rate, the valve for domestic hot water control closes.
0 – 25 l/min
*Min. dT Supply-
DHW
Minimum temperature difference allowed between the supply tempera-
ture from the heat network and the nominal domestic hot water tempera-
