1. Set the C1 switch to position 2 (programming mode). The following image will appear in the
display: S1 xxx %
This means in normal language:
The set value of the first threshold (S1) amounts to XXX % at present. The cursor is at the
lowest-order position, flashing.
2. Now the K2 key may be pressed in order to gradually increase the value displayed by +1 with
every keystroke. The cursor jumps to the left by one digit position if the K2 key is depressed for
two seconds or longer. Again press the K2 key in order to set the left digit to the desired value.
Depress the K2 key for two seconds to return the cursor to the starting point.
3. Press the K3 key in order to transmit the numerical value entered to the parameter memory
(EEPROM) where it will be stored in the event of a power failure.
4. The K1 key may be used in order to scroll to any parameter field.
