Before You Buy

Please select the required Amp rating (10 or 20 Amp) and choose between a simple or waterproof box before purchasing the controller box.

Product Overview

This heavy-duty, plug-and-play temperature controller with dual temperature sensors is versatile, making it ideal for controlling differential and set-point temperatures in a variety of applications.

The controller box is suitable for multiple uses, such as solar water systems for pump control (based on temperature differences between two probes) and heating systems (based on set-point temperature). It features two outputs, allowing it to control both the circulation pump and a heating system. When the temperature difference (T2-T1) reaches the preset values, the circulation pump runs automatically until equilibrium is achieved. The second output can activate electric heating if the solar heating fails to meet the set temperature.

This controller provides a reliable, automated solution for professional temperature control across a range of -50°C to 120°C (-22°F to 248°F).

Key Features

• Dual Sensors with Independent Control: Precisely monitor and manage two separate temperature zones.
• Waterproof Option: Choose a waterproof box with a window cover for added durability.
• Multiple Modes:

1.     Differential temperature mode: One output controls the temperature difference (T2-T1), and the other acts as a thermostat for either T1 or T2.

2.     Two-zone mode: Operate outputs in parallel or series for flexible applications.

3.     Reverse output mode: When one output is open, the other output closes based on differential values.

• Data Recording: Stores maximum and minimum temperatures for both sensors, improving system efficiency.
• Overheating and Freezing Protection: Automatic shutdown with buzzer and flasher alerts.
• Customizable Alarms: Set high/low temperature limits for each zone to ensure safety.
• Timer Delays: Prevent damage from frequent start-ups with two independent delay timers.
• User-Friendly Interface: Large LCD display with red and blue indicators for easy visibility.
• Flexible Temperature Units: Switch between Celsius and Fahrenheit seamlessly.
• Dual Outputs: Offers independent outputs for differential temperature and thermostat control, with reverse output functionality for enhanced control.
• Memory and Factory Reset: Retains settings even after power loss and includes a reset option to restore factory defaults.
• Temperature Calibration: Fine-tune sensor readings for accuracy.
• Circuit Breaker: Provides added safety and reliability.
