Vitodens 100-W, B1HE/B1KE Combi Installation/Service
Boiler
(continued)
System Configuration (parameters)
1100.2 “Set speed of the primary circuit pump in heating mode”
Setting
Explanations
...
Target speed of internal circulation pump
In heating operation
With external demand
With demand in conjunction with a low loss header
Factory settings defined by settings specific to the boiler
The setting range depends on the boiler
1240.0 “Operating mode of primary circuit pump” (not for weather-compensated operation)
Setting
Explanations
1
2
7
“Automatic”
Switched on regardless of current temperature level
Modulating in line with the modulation level of the boiler.
Boiler-specific min. and max. pump speeds are observed.
Shutdown in reduced mode (in conjunction with constant operation or
when no demand via room thermostat)
1411.0 “Clear maintenance messages”
Setting
Explanations
No
Yes
0
1
Clear maintenance messages once maintenance has been performed.
Maintenance messages are active (if present).
Clear maintenance messages once.
1503.0 “Minimum heating output”
Setting
Explanations
...
5 to 100
A limit can be set on the minimum heating output for heating operation.
Factory settings defined by settings specific to the boiler
Adjustable from 5 to 100%
1606.0 “Minimum burner pause time”
Setting
Explanations
0
1
The minimum burner pause time can be set subject to boiler load.
Fixed setting for minimum burner pause time
Factory setting, integral method (see parameter 1606.4)
1606.4 “Integral threshold for burner switch-off”
Setting
Explanations
50
5 to 255
Only effective if parameter 1606.0 has been set to 1.
Factory setting 50 K x min (90°F x min)
Adjustable from 5 to 255 K x min (9 to 459°F x min)
The integral control mode allows for the adjustment of the supply water
temperature dead band (supply temperature overshoot and undershoot) to extend
burner cycle times and help minimize burner short cycling in low heat demand
applications. The greater the setting the wider the dead band, the smaller the
setting the tighter the dead band.
Note:
Parameter values in bold are factory settings.
