Differential Temperature Controller Thermostat with Dual Sensors for Solar Water Heaters, Pools, Boilers, Greenhouses, and More

The Mini Differential Temperature Controller Thermostat is the ideal solution for precise temperature management across various systems, including solar water heaters, swimming pools, greenhouses, HVAC setups, boilers, and cooling systems. This versatile device features dual waterproof sensors and can be programmed to manage the temperature difference (T2-T1) or control two separate zones independently.

* Please select 100-240VDC or 12VDC

Key Features:

• Dual Sensors with Independent Control: Monitor and manage two zones with precision.
• Multiple Modes: Supports Three Differential Modes (F2, F3, F4) and One Two-Zone Mode for flexible applications.
• Overheat and Freeze Protection: Automatic shutdown and alarm alerts via buzzer and flasher for immediate action.
• Data Recording: Records Maximum and Minimum Temperatures for both sensors, improving solar system efficiency in varying seasons.
• Customizable Alarms: Set high/low temperature limits for each zone for added safety.
• Timer Delays: Two independent timer delays prevent damage caused by frequent start-ups.
• Easy Installation: Panel-mounted design with a clear wiring diagram for quick and easy setup.
• User-Friendly Interface: Large LCD display with red and blue zone indicators for clear visibility.
• Flexible Temperature Units: Seamlessly switch between Celsius and Fahrenheit.
• Dual Outputs: One output for differential temperature (T2-T1) and the other acting as a thermostat for either T1 or T2, offering greater control.
• Memory and Factory Reset Option: Settings remain saved in memory, even after power loss, and can be restored to factory defaults if needed.
• Temperature Calibration: Fine-tune sensor readings for T1 and T2 when necessary.
