W1209 24V Temperature Controller with Relay Circuit
The W1209 module has a temperature sensor and a relay circuit. This allows you to easily build a temperature control system. For example, for a 3D printing chamber. With the three buttons set, +, - a target temperature can be set at which the relay switches. This can be used to switch on a fan or heater, for example.
WARNING: The board shows 12V but the relay only switches when it is powered with 24V.
Instructions:
- Connect the temperature sensor, 24V operating voltage (terminal +12V and GND) and your desired consumer (terminal K0 and K1) to the PCB.
- After briefly pressing the SET button, the display flashes. The target temperature can now be adjusted with the + and - buttons.
- If the SET button is pressed for longer than 3 seconds, this calls up the P-menu. Here, various parameters can be set (see table), but mostly P0 is set where one chooses between H and C mode. In C mode, the relay switches when the target temperature is exceeded. In H mode, it switches when it is fallen below.
- Confirm the selected target temperature and P-settings by pressing the SET button again.
- The module now displays the measured temperature in real time and switches the relay according to the P0 value when it reaches the target temperature.
- Possible error codes: LLL=The temperature sensor is not correctly connected. HHH=The measured temperature is outside the measuring range (-50-110°C).

P2 | Upper Limit | 110 | 110 |
P3 | Lower Limit | -50 | -50 |
P4 | Temperature Offset | -0.7 to 7 | 0 |
P5 | Delay Start Time | 0-10 Minutes | 0 |
P6 | High Temperature Alarm | 0-110 | Off |
