3.1.4 Boiler frost protection
If you are leaving your property unoccupied during cold weather, please leave your programmer on constant and your room
thermostat set to 15°C.
▶ If the temperature within the boiler falls below 8°C the pump will run to circulate water and prevent the system freezing.
– If the temperature does not rise to 9°C within 30 minutes of the pump operating, the boiler will fire up to provide heat to
bring the temperature up.
▶ If the temperature within the boiler falls below 5°C the boiler will fire, bringing the boiler temperature up to 12°C to avoid the
possibility of the system freezing.
▶ This process will be repeated until such time that the boiler temperature does not drop below 5°C.
Do not switch the boiler off at the mains power switch or mains fused spur.
