4. OPERATION OF THE INSTALLED PUMP CONTROLLER
In operating modes F1 and F2, the pump controller controls the device connected to it (eg. a pump)
based on the temperature it measures and the set temperature, taking into account the set switching
sensitivity (factory default ±1.0 °C). This means that if the pump controller is set to F1 mode (heating
system circulating pump control) and 40 °C, the 230 V will appear at the controller's output at a tem-
perature above 41.0 °C at a switching sensitivity of ±1.0 °C (the pump connected to it switches ON)
and at temperatures below 39.0 °C the output switches OFF (the pump connected to it switches OFF).
In F2 mode, the output switches exactly the opposite way. You can adjust the set temperature with
the and buttons.
In F3 mode, the output is permanently ON/OFF according to the setting, regardless of the measured
temperature in F3 mode. You can change between ON and OFF by using the and keys.
During normal operation, the device always displays the currently measured temperature on its disp-
lay in all three operating modes. The device indicates the ON/OFF status of its output by means of
the LED above the display.
