Item Type: Temperature Controller Material: PCB Model: XH-W1705 Temperature Control Range: 26~100 Temperature Control Accuracy: 0.1 Backlash Setting: 2/5/10/15 Temperature Measurement Input: Ntc10k/b3950 L=1 Meter Power Supply Voltage: 12v / 24v / 220v Output Type Relay Output (maximum 10a) Appearance Size: Approx.60 x 47mm / 2.4 x 1.9in Package List 1 x Module 1 x Cable The 12/24/220V wiring method is the same. W1705 uses a fivepin relay to control the output. If you need to control heating, use the heating method. If you need to control the heat dissipation, use the heat dissipation wiring method.Temperature setting exampleWhether it is heat dissipation or heating, the temperature that needs to be set is the smallest temperature value in the intervalHow to set the heating modeThe heating mode needs to connect the circuit according to the circuit wiring diagram, and connect the heating device to the "heating" terminal. Examples:Control the electric kettle to boil water, stop when the temperature reaches 80, and the water temperature drops to 70, the electric kettle will boil water again, how to set it?The temperature control interval is [70C 80C], 70C is the minimum temperature value, so you need to set the 70C temperature value, the return difference value is set to 10C, and the 6digit dial code is set to 110000 (12 on 3456 Bottom), the 2digit dial code is set to 10 (1 up and 2 down)How to set the cooling modeThe cooling mode needs to connect the circuit according to the circuit wiring diagram, and connect the cooling equipment to the "refrigeration" terminalExamples:Control the ventilation fan to dissipate, let the temperature drop from 30 to 20, the fan stops working, and the temperature rises to 30c. The fan starts to dissipate again, how to set it?This temperature control interval is [20C 30C], 20C is the minimum temperature value, so you need to set the 20c temperature value, the return difference value is set to 10C, and the 6digit dial code is set to 010111 (2456 up13 down), the 2digit dial code is set to 10 (1 up and 2 down) 1DIP switch can control the factory's heat dissipation without smart heat dissipation, and regulate the temperature of the workshop and plant. 2High temperature control accuracy, the temperature can be controlled between 26~100. 3The temperature controller is made of highquality technology, accurate temperature control, stable and reliable. 4When the temperature of the main part of the product increases, the heat generated is transferred to the bimetallic disc, and the contact is opened or closed by the mechanism when the operating temperature is reached. 5Mainly used in situations where the circuit needs to be turned on and off automatically with temperature changes, so that the temperature of the appliance is controlled within a constant temperature range.
