Controls & accessories

  • Product Outdoor Sensor

    Weather Compensation Kit

    Our outdoor sensor works by measuring the temperature outside the home and adjusting the temperature of the radiators inside accordingly. If the weather is particularly cold outside, the outdoor sensor will communicate with the boiler intelligently to increase the temperature inside. This process also works in reverse allowing the system to operate more efficiency.
