| User guide manual: |
| After applying the power (or a reset), the display shows (----) for about 3 sec. During that time: |
| Do action1: DEFAULT settings: Press both buttons (PB1+PB2) and when the screen turns off release. Be sure to do it (only once) after uploading the hex code in Arduino! |
| Do action2: PRESET settings: Press the PB1 button and when the screen turns off release: |
| P10: Display brightness intensity (0-7) |
| P12: The lower limit for settings value SV1 (range -50/+120 default=-50.0) - Defining settings range limits |
| P14: The upper limit for settings value SV1 (range -50/+120 default=120.0) - Defining settings range limits |
| Additional preset values have no function in this project! |
| Settings (in working mode): |
| SET values: Press the PB1 or PB2 button (until the display goes off then release). The set values that can be changed on the buttons (PB1/PB2=+/-) are displayed. After 2 seconds of inactivity, the value on the display is stored. |
| SET Temperature (SV1): Press the PB1 button (until the display goes off then release). |
| SET Hysteresis (SV2): Press the PB2 button (until the display goes off then release). |
| Status of outputs: |
| Out1: If the measuring temperature is equal to or higher than the set value (SV1) then: Out1=0. When the temperature drops below the set temperature for the set hysteresis value (SV2) then: Out1=1 - (eg. heating function). |
| Out2: Inverse of Out1 (eg. cooling function). |
| Rest of outputs are not in use. |
