ARD -197 XH -W1401 WANT12V DCRED Output10a (MAX) Temperature Temperature -9 C to +99 CTO Arting Value ＞ Stopping Temperature While Detecting Temperature Starting Temperature, Relay Close and Cooling Equipment Start Working.When Detecting Temperature & Le; Stopping Temperature, Relay Disconnect and Cooling Equipment Stop Working.For Example: SET STARTING TEMPERATURE at 30 ℃ ℃ STOPPING TEMPERATURE at 25 or lamp (Blue) Stop Lighting.Start Low Temperature -Heating mode: When Value of Set Starting Temperature ＜ Stopping Temperature, and Detecting Temperature & Le; 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 & Le; 25 ℃. E 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.S Ator Lamp, Means Relay Disconnect and Equipment Stop Working.Digital Tube: Middle Red Digital Tube Displaying Presentation Detected Temperature.Left Green Digital Tube Is Set Starting Temperatereright Green Digital Tube is set. Board Start to Set Starting Temperaturepress Keyboard Stop to Set Stopping Temperature.1. Start High Temperature-Cooling Mode, Set Starting Temperature Value ＞ Stop Temperature Value, When Testing Temperature Starting Temperature, Relay Close and Cooling Equipment Start Working.When Detecting Temperature; Opping Temperature, Relay Disconnect and Cooling Equipment Stop Work.for Example: SET Starting Temperature at 30 ℃ ， Stopping Temperature at 25 ℃ When Tested Temperature & Le; 25 ℃, Relay Disconnecting and Stop Indicator Lamp (Blue) Bright.2.Start Low Temperatur, Heating Mode: Set Starting Temperature Op Temperature, When Detecting Temperature & le; Starting Temperature ， Relay Close and Heating Equipment Start Workingwhen Detecting Temperature Stopping Temperature, Relay Disconnect and Heating Equipment Stop Working, For Example: SET Temperature At 25 Ature at 30 ℃, when detecting temperatures & le; 25 ℃, Relay Close and Indicator Lamp (Red) Bright.
