You can adjust the settings if you wish but I would advise against it. The boiler is protecting itself and pipework by not allowing the installation to freeze. If you think this is a waste just think how much it would cost to replace everything after it has been destroyed by frost. Some insurers won't pay out if they think you have overridden the safety settings.
