BFD110A Rail Solar Thermostat – SingleChannel Temperature Controller for Cooling and Heating Key benefits Accurate automatic temperature control for a single circuit, reducing the need for manual intervention and helping maintain stable system operation. Dualmode operation for heating or cooling applications so the same controller can be used to switch heaters, coolers, pumps, or fans depending on system needs. DINrail format that fits standard control cabinets and distribution boards for convenient, spacesaving installation. Designed for solar system integration and other thermal control applications where reliable singlechannel control is required. What it does Monitors temperature and activates a single output channel to control a heating or cooling device according to the selected mode. Provides automatic switching to protect equipment and maintain the target temperature range for the connected system. Suitable for continuous operation in industrial and commercial control panels. Compatibility and installation BFD110A is compatible with solar thermal systems and common heating and cooling loads such as pumps, fans, heaters, and small refrigeration equipment. Railmounted design for standard DINrail panels. Wiring to a single control output simplifies integration into existing electrical layouts. Compact footprint helps save panel space and keeps installations tidy. Performance and design attributes Singlechannel control dedicated to one temperature loop for straightforward, deterministic operation. Engineered for reliable switching and consistent temperature regulation in daily use. Compact railmounted enclosure designed for control cabinet environments. Practical use scenarios Solar hot water circulation: Automatically switch a circulation pump when the solar collector reaches the desired temperature to transfer heat to storage. Greenhouse climate control: Control a heater or ventilation fan to maintain cropfriendly temperatures using one dedicated temperature loop. Electrical cabinet or equipment cooling: Activate a fan or small cooler to prevent overheating of sensitive components when internal temperature rises. Why choose the BFD110A Simple, purposebuilt singlechannel thermostat for both heating and cooling tasks. Railmount form factor and compatibility with common thermal control loads make it easy to deploy in solar systems and general temperature control installations. Focused functionality and straightforward integration make it a practical choice for system builders and technicians seeking reliable temperature control.
