3.1 OPERATING THE BOILER

3.1.1 SETTING THE BOILER FLOW TEMPERATURE

1. Turn the central heating temperature control knob to the desired level.
The temperature range available is between 30 and 82°C. This not the room temperature but the flow temperature through the
radiators.
The "click" point provides guidance for the maximum temperature setting for optimum energy efficiency.
2. When there is a demand for heat from the boiler, the burner indicator will be illuminate to indicate that the boiler is firing.
The blue operational/fault light will also be illuminated, to confirm that the boiler is operational.

▶ Comfort levels within rooms should be controlled by your thermostatic radiator valves and/or room thermostat.

3.1.2 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.

3.1.3 TURNING THE CENTRAL HEATING OFF DURING THE SUMMER

▶ Turn your programmer/timer to the off position.
▶ Please refer to the programmer/timer manufacturer's instructions.
