ATF

The ATF clamp-on pipe thermostat has a set range of 10 °C - 90 °C. The lower set point of 0°C makes the thermostat particularly suited for frost protection applications.

The ATF which utilises a vapour filled bellows, comes with pipe fixing strap.
The ATF can be used in most frost protection applications which require a pipe thermostat including:

• 2nd stage operation in 2 stage frost protection schemes.
• Frost protection termination function in systems which utilise a room thermostat to initiate boiler operation during periods of low internal room temperature.
