The cooler, heater or fan is connected to a power supply through the relay contacts K0 and K1, and the temperature on/off setpoints are programmed into the W1209 using the onboard Set, Increase and Decrease buttons and display. The relay contacts are then open and closed, acting as a power switch for the cooler/heater, based on the temperature measured by the NTC temperature sensor (included with the module) and the setpoints programmed into the W1209 controller. 3 switches are used to configure the parameters including on & off trigger temperatures. The on-board relay can switch up to a maximum of 125V AC or 14V DC at 20A. The temperature is displayed in degrees Centigrade via its 3 digit display and the current relay state by an onboard LED.
Note that the power supply must be connected to the K0 / K1 relay contacts, the relay is not connected to the 12V support power. If your device operates on 12V, the same power supply can be used for both.
