This chapter describes how to configure the device as a 2-point-controller or 3-point-controller.
This instruction demands that you selected “2P“ or “3P“ as your desired output function.
- Press button 1 
(when not already done). 
The device will be displaying “1.on“ (turn-on-point of output 1).
- Use button 2 and button 3 to set the desired value, the device’s output 1 should be turning on.
- Press button 1 to validate your selection. The display shows “1.on“ again.
- When pressing button 1 again, the device will be displaying “1.off“. (turn-off-point of output 1)
- Use button 2 and button 3 to set the desired value, the device’s output 1 should be turning off.
- Press button 1 to validate your selection. The display shows “1.off“again.
Example: You want to control the temperature of a heating coil, with a hysteresis of +2°C, to 100°C.
Therefore you will have to select the turn-on-point “1.on“ to 100°C and the turn-off-point to
“102°C“. When your heating coil temperature falls below 100°C it will be turned on. When the
temperature rises above 102°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.
When selected ‘2-point-controller‘ you finished configuring your device. Press button 1 to switch over to dis-
play the measuring value.
When selected ‘3-point-controller‘ please follow the instructions given below.
