3.2. Selection of switching sensitivity
The pump controller in modes F1 and F2 switches the output according to the measured temperature
and switching sensitivity. In these modes, it is possible to change the switching sensitivity. By selecti-
ng this value, you can specify how much the device switches the connected pump on/off below/above
the set temperature. The lower this value is, the more constant the temperature of the circulating fluid
will be. The switching sensitivity can be set between ± 0.1 °C and ± 15.0 °C (in 0.1 °C steps). Except
some special cases, we recommend setting ± 1.0 °C (factory default setting). See Chapter 4 for more
information on switching sensitivity.
To change the switching sensitivity, when the pump control is switched ON, in F1 or F2 mode, press
and hold the button for approximately 2 seconds until the „d 1.0" (factory default) appears on the
display. By pressing the and buttons you can change this value in increments of 0,1 °C within the
range of ±0,1 °C and ±15,0 °C.
To exit and save the setting, wait for approx. 4 seconds. The device then returns to its default state.
