60 Delivered condition 60 min
0 to 120 Temperature rise adjustable from 0 to 120 min
Explanations
Priority of DHW heating over the heating circuit
0 Without DHW heating priority
1 With DHW heating priority
Explanations
Only adjust for systems with one heating circuit. See
also parameter 933.7
Heating mode:
0 Weather-compensated without room temperature in-
fluence
1 Weather-compensated with room temperature influ-
ence
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"
8 Room influence factor
0 to 64 Room influence adjustable from 0 to 64
Explanations
Priority of DHW heating over heating circuit pump and
mixer
0 Without DHW heating priority
1 With DHW heating priority
Explanations
The flow temperature of the heat generator is higher
than the flow temperature of the heating circuit with
mixer by an adjustable differential temperature. See
also chapter "Function description".
8 Differential temperature in delivered condition 8 K
0 to 20 Differential temperature adjustable from 0 to 20 K
