This unit is ideal for controlling lamps or 12 volt heaters / coolers that you might have. Just plug into a 12VDC source in the V12 and GND to power the system, it comes with a 52cm probe that will start measuring the temperature, you can change the settings in the menu to have a delayed start to measure the temperature . The use of a relay can be used as a cooler when the temperature increases the fan turns on or as a heater when the temperature decreases turn on the system. Choose one or the other can be done in the menu settings. It is a simple "plug and play" device that should allow you to start with your projects as the relay will act as a normally open switch, when the thermostat reaches the programmed target temperature it will activate the relay to create a closed circuit. Comes with an alarm to indicate if the temperature rises past the temperature of your setting. This feature is disabled by default in the menu settings.
