Start low temperature,heating mode:set starting temperature stop temperature,when detecting temperature starting temperature,relay close and heating equipment start working
When detecting temperature stopping temperature,relay disconnect and heating equipment stop working,For example:set temperature at 25,stop temperature at 30,when detecting temperature 25,relay close and indicator lamp (red) bright.
 
Manual instruction
1. Start high temperature -cooling mode:when value of set starting valuestopping temperature while detecting temperature starting temperature,relay close and cooling equipment start working.When detecting temperature stopping temperature,relay disconnect and cooling equipment stop working.For example:Set starting  temperature at 30,stopping temperature at 25,when detecting temperature value 25, relay disconnect and indicator lamp (blue)stop lighting.
2. Start low temperature-heating mode:when value of set starting temperature stopping  temperature,and detecting temperature starting temperature,relay close and heating equipment start working. Detecting temperature stopping temperature,relay disconnect and heating equipment stop working.For example,set starting temperature at 25,stop temperature at 30 .while detecting temperature 25,relay close and start indicator lamp (red )lighting.When detecting temperature 30 ,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.
