This is a device that regulates the temperature of pet heaters, etc. It uses a sensor attached to the thermostat to detect the air temperature and maintain a constant temperature based on the set value. When the [power on] lamp is lit, the pet heater is on. When the lamp is off, the pet heater is off. The temperature may fluctuate above or below the set value depending on the sensor's position and the environment. Do not rely solely on the thermostat's set temperature; also install a digital thermometer to check if the temperature is being maintained. 【Rated Voltage】AC100V 50Hz/60Hz 【Connectable Heater Capacity】310W ※Up to 3 heat sources of 100W can be connected 【Control Temperature Range】15-40 degrees Celsius ※Error/Plus or minus 1 degree Celsius 【Body Size】W56 x H85 x D32mm 【Included Cables】Power cord 1m, Sensor cord 1m, Outlet cord 0.2m 【Notes】 ・This product does not have a heat-retaining effect.
