Coding
Coding in the Delivered Condition
55:0 DHW tank heating, hysteresis ± 2.5 K.
56:0 Set DHW temperature adjustable from 50 to
140°F (10 to 60°C).
58:0 Without auxiliary function for DHW heating.
59:0 DHW tank heating:
Start point: Set value −2.5 K
Shutdown point: Set value +2.5 K
5A:0 For DHW heating:
The set boiler water temperature is determined
by the highest system supply temperature
demand.
60:20 During DHW heating, the boiler water
temperature is up to 20 K higher than the set
DHW temperature.
61:1 The circulation pump for DHW tank heating
is started immediately.
62:10 Circulation pump with a run-on time after DHW
tank heating of up to 10 min.
63:0 Without auxiliary function for DHW heating.
67:40 For solar DHW heating:
Set DHW temperature 104° F (40° C).
Reheating is suppressed above the selected set
temperature (DHW heating by the boiler only if
solar energy is not sufficient).
68:8 With 2 DHW tank temperature sensors (code
"55:2"):
DHW tank heating stop point at set value x 0.8.
69:7 With 2 DHW tank temperature sensors (code
"55:2"):
DHW tank heating start point at set value x 0.7.
6A:75 Runtime, servomotor, mixing valve, heat
exchanger set, Vitotrans 222, 80 and 120 kW:
75 sec.
Possible Change
55:1 Adaptive DHW tank heating enabled (see page 96).

system (see page 97).
56:1 Set DHW temperature adjustable from 50 to
203°F (10 to 95°C).
Note: Observe the max. permissible DHW
temperature. Reset the adjustable high
limit "R".
58:1 Input of a second set DHW temperature,
to adjustable from 34 to 203°F (1 to 95°C).

by the DHW tank supply temperature demand.
60:5 The differential between the boiler water
to temperature and the set DHW temperature is
60:50 adjustable from 10 to 50 K.
61:0 The circulation pump for DHW tank heating is
started depending on the boiler water temperature.
