The XH-M452 Digital Temperature & Humidity Controller is an industrial-grade, high-precision dual-control module. At Electrapac, we recommend this as the "all-in-one" brain for high-success-rate egg incubators, specialized greenhouses, and climate-controlled storage cabinets.

Product Overview

The XH-M452 utilizes a 12V DC power input to simultaneously monitor and control both heating/cooling and humidifying/dehumidifying devices. It features a dual-display LED screen showing real-time data and uses a high-accuracy SHT20 sensor on a flexible lead for precise environmental tracking. With independent relay outputs for temperature and humidity, you can automate your entire climate system with one compact board.

Key Features for Electrapac Customers

• Dual-Purpose Control: No need for separate devices. Control a heater/fan and a humidifier/dehumidifier from the same interface.

• Precision SHT20 Sensor: Unlike cheaper DHT sensors, the SHT20 provides laboratory-grade stability and faster response times, which is critical for sensitive egg incubation.

• Independent Settings: Set separate "Start" and "Stop" values for both temperature and humidity to create a custom "buffer zone" (hysteresis), preventing your equipment from flickering on and off too rapidly.

• Non-Volatile Memory: All settings are saved automatically. If you have a power outage, the XH-M452 will resume your programmed cycle immediately upon power-up.

• Clear Visual Feedback: The Red LED displays temperature, while the Blue LED displays humidity, making it easy to check status at a glance from across the room.

Programming & Wiring Guide

To set up your system with parts from www.electrapac.com:

1. Temperature Control:

   • Set Start: Long press the (+) button under the Red display until it flashes, then adjust.

   • Set Stop: Long press the (-) button under the Red display until it flashes, then adjust.

   • If Start < Stop = Heating Mode; If Start > Stop = Cooling Mode.

2. Humidity Control:

   • Use the same process with the (+) and (-) buttons under the Blue display.

   • If Start < Stop = Humidification; If Start > Stop = Dehumidification.

3. Wiring: The relays act as "switches." You must provide the power source for your heater or humidifier through the relay terminals.

Primary Applications

• Automatic Egg Incubators: Maintaining the perfect 37.5°C and 50-60% humidity required for hatching.

• Mushroom Cultivation: Keeping high humidity levels without letting the temperature spike.

• Tobacco or Wine Storage: Preserving high-value goods in a stable, moisture-controlled environment.

• Vivariums & Pet Enclosures: Mimicking tropical climates for exotic reptiles or plants.
