3.1.9 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.
3.1.10 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 immediately, bringing the boiler temperature up to 15°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.
3.1.11 TURN OFF THE OPERATION/FAULT DIAGNOSTIC LIGHT (BLUE)
Your new Greenstar iSystem Compact boiler is designed to use as little electricity as possible during operation and in stand-by
mode. To further enhance your energy saving during stand-by, you may choose to deactivate the Operation/fault diagnostic light.
The light will still flash to alert you to a possible fault, but will stay off when the boiler is in stand-by mode. Please ask your installer
to activate this feature.
NOTICE: The boiler must be switched on with a gas supply in order for the built -in auto frost protection to work as
described.
