Coding in the delivered condition
59:0 Cylinder heating:
Start point -2.5 K
Stop point +2.5 K
5E:0 Circulation pump for cylinder heat-
ing stays in control mode at "Exter-
nal blocking" signal.
5F:0 Circulation pump for cylinder heat-
ing stays in control mode at "Exter-
nal demand" signal.
60:20 During DHW heating, the boiler
water temperature is max. 20 K
