9.2. 2-point-controller, 3-point-controller 

This chapter describes how to configure the device as a 2-point-controller or 3-point-controller.                                     
This 

instruction demands that you selected “

Finish adjustment: 

Press

 Button 1

 as often till the device executes a reset. The values will be stored at it 

 

Example: You want to control the temperature of a heating coil, with a hysteresis of +2°C, to 

120°C.      Therefore you will have to select the turn-on-

point “1.on“ to 120°C and the 

turn-off-

point to “122°C“. When your heating coil temperature falls below 120°C it will be 

turned on. When the temperature rises above 122°C the heating coil will be turned off. 

 

Note: Depending on the inertia of your heating coil an overshooting of the temperature 

 

may be possible

 

9.3. 2-point-controller with alarm function 

This chapter describes how to configure the device as a 2-point-controller with alarm function.                                     
This instruction demands that you selected “

Finish Adjustment: 

Press

 Button 1

 as often till the device executes a reset. The values will be stored at it.

 

 

Alarm-outputs are inverted! This means, that the output will be active when 
there is no alarm!

 

Example: You want to control the temperature of a cooling chamber between 

–20°C and –22°C.              

Therefore you will have to select 

–20°C for the turn-on-point 1 “1.on“ and –22°C for the 

turn-off-

point 1 “1.off“. When the temperature rises above –20°C the device turns its out-

put 1 on, when falling below 

–22°C the device will turn its output 1 off .
