W1088 Dual LED Digital Temperature Sensor Meter Controller Electric Heating Thermostat 220V Aquarium Incubator Thermoregulator Features: Heating or cooling control Red and blue dual led display Independent Dual-way temperature controller Temperature display resolution 0.1 Directly power output Application range is like home temperature control, farm, various cold storage, greenhouse, aquarium, etc. Specifications: Display Type: Digital Shell Material: ABS + PCB Temperature Sensor: NTC 10K Senor Length: 1m Temperature Measuring Range: -55 C ~ 120 C Resolution: 0.1 C Accuracy: 1 C Power Supply: 110-220VAC 50/60Hz, 12V DC , 24V DC(Please choose power supply when ordering) Relay Contact Capacity: Two Relay Max 10A Output Type: Direct Output Size: 72*56*31mm Packing List: 1 x Temperature Controller 2 x Waterproof Sensor NO.1 Work Signal NO.1 Measured Temperature NO.1 Start Temperature Set NO.1 Stop Temperature Set NO.2 Work Signal NO.2 Measured Temperature NO.2 Stop Temperature Set NO.2 Start Temperature Set Item NO. Operation instruction: A. Set The Starting Temperature: Press the UPbutton once to display the starting temperature. Long press the UPbutton for about 3 seconds,The required temperature can be set by the UPand DOWNbuttons. B. Set Stop Temperature: Press the DOWN button once to display the stop temperature. Long press the button for about 3 seconds and the stop temperature number flashes. The required temperature can be set by the UPand DOWNbuttons. C.Press UP button andUp button at the same time to setting mode: Press UP and UP buttons for 3 seconds at the same time to enter the setting mode, display P0, the first group temperature delay, press UP and DOWN to adjust, 0~60 minutes, default 0, after adjustment, press UP since P1, the second group temperature delay, press UP and DOWN to adjust, 0~60 minutes, default 0. P2-P3 Has no mode Menu Instruction Code Function Set Range Default P0 : Delay start 0-60 minutes 0 P1 : Delay start 0-60 minutes 0 P2 / / / P3 / / / D. Reset Factory Settings: When the power is on, press the DOWNand DOWNbuttons at the same time for 3 seconds. The reading shows 888, and then the controller automatically jumps to the detectedtemperature. E. Temperature Correction: Press UPand Downat the same times for 3 seconds to display 0.0, and then set the value by pressing theUpand Downbuttons. Positive Value = Measured Value +Corrected Value(NO.2 temperature correction is the same method, pressUP andDown buttons) F. Heating Cooling Method: Operation Method Heating Mode Start temperature < Stop temperature Program automatically determines the working mode is heading mode Cooling Mode Start temperature >Stop temperature Program automatically determines the working mode is cooling mode Note: 1.12V/24VDC W1088can use the transformer or 12V/24V DC Power Supply. 2. W1088 isDirect Output: The output and input voltage are synchronized. When the temperature controller is working ( the indicator light is on), the output voltage is the same as input voltage; When the temperature controller is off (the indicator light is off), the output will do not have voltage. _x000D_
