Control Parameters; External Demand Processing - Samson TROVIS 5757-3 Configuration Manual

Functions and parameters

2.6 Control parameters

Parameters
P07: Proportional-action coefficient KP
P08: Reset time Tn
P09: Derivative-action time Tv
P10: Actuator transit time Ty
The actuator transit time Ty actuator transit time for valve travel (P10) reflects the time that the
valve needs to move through the range from 0 to 100 % without stopping. The default setting
is 25 s.
NOTICE
!
The default setting is based on the rated travel of 6 mm. The actual transit time can be deter-
mined by the "Start transit time measurement" parameter. See section 4.4.

2.7 External demand processing

The device can process an external demand for heat depending on the configuration. A
measuring range (Xmin to Xmax) is assigned to the current signal (0 to 20 mA or 4 to
20 mA, set point). The external hot water set point has priority over the internal set point.
NOTICE
!
Only a Pt 1000 sensor can be used to measure the hot water temperature when the function
for an external demand is active.
