Digital Thermostat Temperature Controller
- Brands China Code: TEMP-W1209-MOD
The W1209 is an incredibly low-cost yet highly functional thermostat controller. With this module, you can intelligently control power to most types of electrical devices based on the temperature sensed by the included high-accuracy NTC temperature sensor. Although this module has an embedded microcontroller no programming knowledge is required. 3 tactile switches allow for configuring various parameters including on & off trigger temperatures. The onboard relay can switch up to a maximum of 240V AC at 5A or 14V DC at 10A. The current temperature is displayed in degrees Centigrade via its 3-digit seven-segment display and the current relay state by an onboard LED.
Module Power:
The module is powered from 12VDC which is connected to the screw terminal block. This can come from an AC wall adapter or a similar power source.
Display:
Buttons:
There are 3 buttons on the module that you can fiddle with:
Setting Trigger Temperature:
Setting Parameters:
Because the user interface is limited to a 3-digit display and 3 push buttons, setting parameters can seem a little daunting at first, but it is actually quite easy to use as explained in this section.
To enter the parameter setting mode, you long press the SET button for about 3 seconds. When the button is released the display will show ‘P0‘ which is the first parameter setting. You may find that you need to long press the button twice before P0 is displayed. Once in parameter setting mode, pressing the +/- keys allow you to scroll between each of the parameters that can be set.
There are 9 parameters that can be programmed into the module:
