Working Principle
1.cooling mode(set the start temperature>stop temperature):when detecing the ambient temperature is over the start temperature, the relay close the cooling device will start work, when the ambient teperature is below the stop temerature, the relay open, the cooling machine stop working.
2.heating mode(set the start temperature < stop temperature):when detecting the ambient temperature is below the start temperature, the relay close, the heating device will start working, whent the ambient temperature is over the stop temperature, the relay open, heating machine stop working.

Setting Insturctions:
Short press the "SET" key to set the up and down temperature limit values, the up and down LED dispaly will flash, then press"+" and "-" to regulate the value. After setting and wait 5s the module will save the parameter automatically
Long press the "SET" key step into the current temperature measuring and working mode checking interface. The up LED display the current temperature and the down LED display the working mode(C represent cooling mode, H represent heating mode, OFF represent stop)
