Differential Control
= stabilization of the temperature between two sensors.
Stabilization of the temperature difference between e.g. S1 and S2 provides 'smooth'
operation.
DC N12
Differential control in normal operation between sensor S1 and S2. (fs = --)
Setting range: DC N12 to DC N65, DC I12 to DC I65)
DC -- = Differential control is deactivated.
DVD 10
The set value of the differential control is
10
K. According to the example there-
fore the temperature difference between S1 and S2 is stabilized at 10K.
Warning: DVD must always be greater than the switch-off differential of the basic
function. With a smaller DVD the basic function blocks the release of the pump
before the speed control has reached the set value. (fs = 10K)
Setting range: 0.0 to 9.9K in increments of 0.1K; 10 to 99K in increments of 1K
If the absolute value control (stabilization of a sensor) and the differential control (stabilizing
the differential between two sensors) are both active at the same time, the “slower speed
wins out”.
Event control
= If a set temperature event occurs, the speed control starts, thus keeping
a sensor constant.
When S3 has reached 60°C (activation threshold) for example S1 is kept at a certain tem-
perature. The respective stabilization of the sensor functions as it does for the absolute value
control.
EC N31
Event control in normal operation; an event occurring at sensor S
3
leads to
stabilization of the sensor S
1
. (fs = --)
Setting range: EC N12 to EC N65, EC I12 to EC I65
EC -- = Event control is deactivated.
DVE 60
The threshold value of the event control is
60
°C. Above a temperature of 60°C
at S3 the speed controller is activated. (fs = 60°C)
Setting range: 0 to 99°C in increments of 1°C
DVC 130
The set value of the event control is
130
°C. As soon as this event occurs, S1 is
stabilized at 10°C. (fs = 130°C)
Setting range: 0 to 199°C in increments of 1°C
The event control “overwrites” the speed results from other regulation methods. Hence,
a set event can block the absolute value control or differential control.
