2-Pack XH-M452 Humidity Controller Digital Thermostat, Dual Relay 10A | DC 12V, LED display, independent heating and humidity control, for furnace, humidifier, and incubation projects

About this item

• [COMPLETE 2-PACK SET & SPECIFICATIONS]: Each pack includes 2 XH-M452 control module boards and 2 integrated temperature and humidity sensor probes with cables. Specifications: DC 12V power supply, temperature range -20°C to 60°C, humidity range 00% to 100% RH. High precision control at 0.1°C and 0.1% RH. Features 10A dual relay output. Compact board size of 65 x 55 x 28mm fits easily into standard project boxes.
• [INDEPENDENT DUAL RELAY OPERATION]: This dual-function module features two separate relays to independently manage heating/cooling and humidification/dehumidification equipment. The large LED digital screen displays real-time ambient conditions, providing simultaneous readouts for accurate monitoring without the need to toggle between different screens.
• [UPGRADED DIY REPLACEMENT SOLUTION]: Ideal for replacing traditional twist-knob controls that cause water valves to bang during transitions. By allowing you to set separate ON and OFF set points (for example, turn on at 45% and turn off at 50%), this board prevents short-cycling and ensures equipment runs smoothly. Note: Requires a separate DC 12V power supply or step-down buck converter for 24V AC furnace systems.
• [STEP-BY-STEP PROGRAMMING]: Simple push-button setup. To set start parameters: long-press the "+" button for 3 seconds until the display flashes, then adjust the value. To set stop parameters: long-press the "-" button for 3 seconds until flashing, then adjust. To restore factory settings: press and hold the temperature and humidity "+" keys simultaneously for 3 seconds until the digital display reads 888 888.
• [VERSATILE MOUNTING & APPLICATION SCENARIOS]: The wired sensor probe allows the control board to be mounted near a thermostat while the sensor is placed directly in the target environment. Perfect for whole-house HVAC systems, control cabinets, breeding incubators, printing plants, basement ventilation, and custom home climate control projects.
