428.4 "Duration for set flow temperature increase, heating circuit 3"
Setting Explanations
Duration for set flow temperature increase
See also chapter "Function description"
60 min 60 Delivered condition 60 min
0 to 120 Temperature rise adjustable from 0 to 120 min
933.3 "Priority, DHW heating, heating circuit 1"
Setting Explanations
Priority of DHW heating over the heating circuit
Note
If several heating circuits are connected, only adjust in
conjunction with low loss header.
Off 0 Without DHW heating priority
DHW 1 With DHW heating priority
933.6 "Operating mode of heating circuit 1"
Setting Explanations
Only adjust for systems with one heating circuit.
Heating mode:
Weather-compensated without room tem-
perature hook-up 4 Weather-compensated without room temperature in-
fluence
Weather-compensated with room tempera-
ture hook-up 7 Weather-compensated with room temperature influ-
ence (see also parameter 933.7)
933.7 "Room influence factor, heating circuit 1"
Setting Explanations
The higher the value, the greater the influence of the
room temperature on the set flow temperature of the
heating circuit (heating curve). Operation with room
temperature hook-up must be set for the heating cir-
cuit (parameter 933.6). Only change the value for sys-
tems with one heating circuit.
For a sample calculation, see chapter "Heating curve"
in the "Function description"
