ThermoMart DIN302 Digital Dual-Relay Temperature & Humidity Controller for Humidors & Wineadors | With High/Low Alarm System

Product Description:

Protect your cigars by simply dropping the sensor into your existing humidor—an active buzzer and flasher will trigger the moment your temperature or humidity exceeds your safe zones. Or, if you are building a custom 'Wineador' (converting a wine fridge), the DIN302 dual-relay controller delivers the exact automated precision required for long-term aging.

Designed for active control and vigilant monitoring, it features dedicated outputs for both temperature and humidity. Drop the 1-meter precision sensor into your humidor to use it as a high-accuracy standalone monitor with an active buzzer/flasher alarm, or wire it directly to your climate appliances for completely automated, hands-off environment management.

The Science of Perfect Storage:

To properly preserve, age, and protect cigars from mold or cracking, a humidor must mimic a tropical climate of 21°C (70°F) and 70% humidity. While small desktop boxes can rely on passive moisture packs, larger cabinet and DIY humidors require an Active Electronic System. This controller automates your climate management, acting as the digital brain to precisely engage humidifiers and cooling units the moment your environment shifts.

Key Features:

* Dedicated Dual Outputs: Features two independent 10-Amp relays—one dedicated to temperature control and one dedicated to humidity control. You also have the flexibility to wire them in parallel; for example, triggering a single exhaust fan if either the temperature or the humidity reaches a certain threshold.

* Customizable High/Low Alarms: Never lose a collection to a dry-out or a mold spike. Set your specific safe zones, and the integrated buzzer system will instantly alert you with a beeping sound and flash if your environment breaches your programmed high or low limits.

* Max & Min Recording: Track and manage your humidor effectively. The controller automatically records and saves the maximum and minimum temperature and humidity values, allowing you to monitor long-term climate stability.

* Device Protection Delay Timer: Crucial for Wineador builds! Includes a programmable delay output protection (from 0 to 60 minutes) that prevents rapid on/off cycles, effectively protecting your expensive wine fridge compressors, fans, or humidifiers from burnout.

* Intelligent Auto-Switching: Automatically recognizes your intent based on your start and stop set points, flawlessly switching between heating/cooling or humidifying/dehumidifying modes without manual intervention.

* At-a-Glance Dual Color LED Display: Quickly read your current climate status from across the room with distinct readouts featuring red for temperature and blue for humidity.

* Switchable °C/°F & Micro-Calibration: Easily toggle between Celsius and Fahrenheit (Parameter P0). Additionally, manual calibration for both temperature and humidity (from -10 to +10) ensures medical-grade accuracy against your trusted analog hygrometers.
