50 to 140° F (10 to 60° C)

56:1 Set DHW temperature adjustable from

50 to above 140°F (10 to above 60°C)

Note: Subject to boiler coding card of connected

boilers. Observe the max. permissible

DHW temperature.

58:0 Without auxiliary function for DHW heating 58:10

58:95

Input of a second set DHW temperature,

adjustable from 50 to 203°F (10 to 95°C)

(observe coding address “56”)

59:0 DHW tank heating:

Starting point -2.5 K

Stopping point +2.5 K

59:1

59:10

Starting point adjustable from 1 to 10 K below

the set value

5A:0 For DHW heating:

The set supply temperature is determined by

the highest system supply temperature demand.

5A:1 For DHW heating:

The set supply temperature is determined by the

DHW tank supply temperature demand.

60:20 During DHW heating, the boiler water

temperature is max. 20 K higher than the

set DHW temperature

60:10

60:50

The differential between the boiler water

temperature and the set DHW temperature

is adjustable from 10 to 50 K
