thermio™ essential BFT

PRODUCT DESCRIPTION

The thermio™ essential BFT is a mechanical frost thermostat of ErP class I that offers automatic and energy-efficient frost protection and is used in central heating systems as well as pipes in areas prone to freezing. Its tamper-proof temperature adjustment knob for the temperature setpoint allows optional limitation of the temperature range and serves as a lock for the set temperature and as protection against unauthorised access by third parties.

BENEFITS

  • Offers automatic, energy-efficient frost protection for central heating systems and pipes in locations at risk of frost damage, and for general building protection.
  • The tamper-proof temperature adjustment knob allows optional limitation of the temperature range and serves as a lock for the set temperature and as protection against unauthorised access by third parties.
  • Surface mounting for easy and quick installation
  • Very easy to use due to the large temperature adjustment knob with a precise clearly marked dial and precise indicator markers as well as a manual ON/OFF switch
  • A broad temperature control range of -5 °C to + 15 °C ensures that the system is activated in frost conditions

APPLICATIONS

  • Boiler
  • Heating systems
  • Water pipes
  • Storage heater
