Circuit board
1. Jumper:
- Selection of output range:
voltage output signal:
current output signal:
2. Display:
- place for optional display
3. LED:
D1 red: - lit permanently during the calibration routine
- lit up shortly when reset to factory calibration settings
D2 green: - flashes during operation
- lit up if humidity / temperature sensor is damaged
4. Push-Button: S1:
- for 1 point humidity / temperature calibration (humidity > 50%RH)
- for 2 point humidity / temperature calibration (high calibration point)
- to store the calibration settings
S2:
- for 1 point humidity / temperature calibration (humidity < 50%RH)
- for 2 point humidity / temperature calibration (low calibration point
- to exit the calibration procedure (without storing the calibration values)
S1+S2: - to reset to factory calibration settings
5. Level Potentiometer: - set the threshold (model EE23 with alarm module only)
6. Hysteresis Potentiometer: - set the hysteresis (model EE23 with alarm module only)
