    Okay, so not biking related! We've just had a new boiler and now have a wireless thingy on the wall. It is a Radio Tybox. What is confusing me, is you have two temp settings, Comfort and economy. Please explain?!!! The nearest I can guess is that comfort is the setting you set your heating to...
