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.
When selected ‘2-point-controller‘ you finished configuring your device. Press button 1 to switch over to
display the measuring value.
When selected ‘3-point-controller‘ please follow the instructions given below:
- Press button 1
