17.1.1.  ON/OFF controller

The ON/OFF controller doses with 100% until the measured value reaches the set point, and then stops.

Besides set point and controller type you can set the following 

 parameter:

Hysteresis

For the on/off controller you can define a hysteresis. This prevents constant switching of the relays  

in the vicinity of the set point – the relay switches only when the difference between set point and 

measured value exceeds half the hysteresis value.

17.1.2.  P controller

The P controller reduces the dosing when the difference between set point and measured value is 

smaller than the specified P range. Within the p range, the controller output is proportional to the 

 remaining deviation. When the measured value reaches the set point, dosing stops.

Besides set point and controller type you can set the following 

 parameters:

 

P range

The P range or proportional range is the range in which dosing is reduced proportional to the deviation 

between set point and measured value. The bigger the P range, the softer the control.

To find the ideal setting, start with a big P range and reduce it until the measured value oscillates 

around the set point in a stable manner. The ideal value is then twice the current value. If the measured 

value still oscillates, use a slightly higher value.
