Radiant cooling systems are an efficient and effective way to regulate the temperature in a building or space. These systems work by circulating cool water through pipes or tubes beneath a structure’s floor, walls, or ceiling. This cool water absorbs heat from the surrounding air, helping keep the space comfortable. The challenge with radiant cooling systems is accurately monitoring and controlling the temperature of the floor surface. If the floor is too cold, it can be uncomfortable for occupants and may result in decreased energy efficiency. On the other hand, if the floor is too warm, it may not effectively cool the space. Another one is to monitor the temperature for a wide floor surface area.


7 Channel Actuator controller (Gateway)


To address the challenge of accurately monitoring and controlling the temperature of a radiant cooling system, a custom solution has been designed using Bluetooth Low Energy (BLE) surface temperature beacons, a wireless thermostat, and a 7-channel actuator controller (gateway).

  1. Install BLE surface temperature beacons on the floor in a representative location. These beacons continuously measure the temperature and transmit the readings at a fixed interval (1 minute by default).
  2. Data received from wireless surface temperature beacons are sent to the thermostat, and the thermostat will transfer the data to the 7-channel actuator controller (gateway)
  3. Program the wireless thermostat to control the temperature of the space based on the temperature readings from the wireless surface temperature beacon and to measure the space’s humidity to prevent floor condensation.
  4. Program the 7-channel actuator controller (gateway) to receive temperature readings from the thermostat and to control the flow of cool water through the radiant cooling system based on these readings.
  5. Monitor the system’s performance using the thermostat and the 7-channel actuator controller (gateway). Adjust the settings as needed to ensure that the floor’s temperature is maintained within a comfortable range.

This solution offers precise temperature control, energy efficiency, comfort for occupants, and easy maintenance and calibration. By accurately controlling the floor’s temperature, the radiant cooling system can operate at maximum efficiency, reducing energy consumption and costs while ensuring the comfort of the space’s occupants. Wireless technologies also simplify the installation and maintenance of the system, as it eliminates the need for wiring between the various components.


  • Precise temperature control: The wireless surface temperature beacon allows for real-time temperature monitoring of the floor surface, ensuring that the radiant cooling system operates optimally.
  • Energy efficiency: By accurately controlling the floor’s temperature, the radiant cooling system can operate at maximum efficiency, reducing energy consumption and costs.
  • Comfort: By maintaining a comfortable temperature range, the radiant cooling system helps ensure the convenience of the space’s occupants.
  • Easy maintenance and calibration: The BLE surface temperature beacon, thermostat, and 7-channel actuator controller (gateway) are easy to access for maintenance and calibration, ensuring the system operates at its best.
