Description / note
NominalVoltage
(word)
360 ... 440V
[400]
Sets the nominal voltage between two phases of the three-phase current,
this voltage becoming the reference for voltage correction.
The setting can be fine-tuned to steps of 1V.
VoltageTolerance
(word)
0 ... 100V
[0]
Tolerance (±), with reference to the nominal voltage, which is to provoke a
warning if exceeded.
Note:
The limits of the rated voltage 400 V AC ± 10% (360 V AC / 440 V AC) can
not be exceeded and will always lead to an error message.
The setting can be fine-tuned to steps of 1V.
From software 2:05
Mains voltage extension 350 ... 450 VAC:
From the voltage 400 V AC ± 10% (360 V AC / 440 V AC), a module warn-
ing is issued.
An error message and shutdown occurs from 350 V AC or 450 V AC.
MaxPhaseAngle
(word)
20 ... 170°
[90]
Maximum phase cutting angle. (180° - setting)
The setting can be fine-tuned to steps of 1 degree.
RunupTime
(word)
1000 ... 20000ms
[0]
Time set for phase-fired start of radiators. (soft start)
The setting can be fine-tuned to steps of 1ms.
MinHeatingPower
(word)
0 ... 100%
[0]
Rock-bottom control value regardless of default. The setting can be fine-
tuned to steps of 1%.
MaxHeatingPower
(word)
0 ... 100%
[0]
Absolute peak control value regardless of default. The setting can be fine-
tuned to steps of 1% and must needs be greater than MinHeatingPower.
Note: If this parameter is set to 99%, errors "open load" and "TRIAC failure"
can be detected.
