Building Heating & Hydronic Flow Controller

Building heating controller PCB with relays and terminal blocks for hydronic systems

Droid Technologies designed and developed a building heating system controller for hydronic heating and hot-water flow management across residential and commercial buildings.

The controller is based on an STM32 microcontroller and manages valves, pumps, sensors, and distributed heating zones to control the circulation and distribution of heated water through building pipe networks.

The system supports RS485, Ethernet, and CAN interfaces, enabling integration with distributed controllers, sensors, actuators, building automation systems, and external monitoring platforms.

Droid Technologies delivered hardware design, PCB development, embedded firmware, communication interfaces, power electronics, control logic, and complete system integration.

Key features and engineering scope:

• STM32-based embedded controller
• Hydronic heating and hot-water flow control
