ITEM NAME:DC12V Digital Thermostat Intelligent Temp Control -9 to 99 Celsius Temperat A9E8 DC12V Digital Thermostat Intelligent Temp Control -9 to 99 Celsius Temperat A9E8 Manual instruction 1. Start high temperature -cooling mode:when value of set starting value Greater than stopping temperature while detecting temperature greater than equal starting temperature,relay close and cooling equipment start working.When detecting temperature less than equal stopping temperature,relay disconnect and cooling equipment stop working. For example:Set starting temperature at 30 Celsius ,stopping temperature at 25 Celsius ,when detecting temperature value less than equal 25 Celsius , relay disconnect and indicator lamp (blue)stop lighting. 2. Start low temperature-heating mode:when value of set starting temperature Less than stopping temperature,and detecting temperature less than equal starting temperature,relay close and heating equipment start working. Detecting temperature greater than equal stopping temperature,relay disconnect and heating equipment stop working. For example,set starting temperature at 25 Celsius ,stop temperature at 30 Celsius .while detecting temperature less than equal 25 Celsius ,relay close and start indicator lamp (red )lighting.When detecting temperature greater than equal 30 Celsius ,relay disconnect and stop indicator lamp (green) lighting. Start indicator lamp:Start(red) indicator lamp,means relay close and equipment start working. Stop indicator lamp:Stop(green)indicator lamp,means relay disconnect and equipment stop working. Digital tube:Middle red digital tube displaying present detected temperature. Left green digital tube is set starting temperature Right green digital tube is set stopping temperature Press keyboard START to set starting temperature Press keyboard STOP to set stopping temperature.
