Individual zero
point
Individual zero point, this is the smallest
value which is controlled on the analogue
output
0 … 5 V
Set point
(Load / Control)
With sufficient load regulates the analogue
output to this value

kW
Max. power
(Load / Control)
Max. power consumption of the controlled
load at 10 V
0,1…500,00 kW
Control
speed
Slow (20%)…fast (90%),
Control response = (difference between the
set point-
actual value) * 20…90%
20…90 %
Control interval
The set point value is readjusted in this
interval; fast (0.5s) … slow (60.0s)
00,5…60,0 s
Control tolerance
Difference set point actual > Control
tolerance = Failure of the load is detected,
e.g. due to a thermostat being switch-off;
load on the analogue output is not taken into
account by K1-3 when additional loads are
switched on
