You can access hidden parameters by holding down the
buttons SET + for 3 seconds in the programming level HY.
The message Pr2 appears.
Preset possibility only for Set-value 1
which affects the first control output.
This value determines the bandwidth
(on both sides of the set-value) that
exist within the proportional control.
Determines the integral behaviour of the
controller. The greater the deviation,
the higher the effect.
Determines the differential behaviour of
the controller. The greater the deviation,
the higher the effect.
Time between 2 consecutive
following measurements for the
calculation of dt. A smaller value
increases the response time.
With this parameter, the proporti-
onal control deviation can be moved up /
down. The value will be defined as the
same amount, but in the opposite
direction to the deviation detected.
Range (on both sides of the set-value)
within which the integral action time is
effective. The higher the value,
the greater the effect.
Minimum time during which the out-
put relay is switched on and off.
If the temperature is outside the band
(on both sides of the set-value), a new
Soft-Start will be initiated.
(0 = deactivated)
This value determines the stepwise
set-value increase from SET1.
(0 = deactivated)
clock time for dynamic set-value-
control with regard to dSi (SOFT-Start).
