Heatline C24/C28 Problem?

I have a heatline C24/C28 condensing wall mounted combination boiler installed (I cannot determine if it is C24 or C28 mind!), and the heating and hot water works fine, I just have one problem.

While the boiler's central heating is set on the timer to be "off", the boiler continually makes a noise as if it is going to start then it clicks off, it repeats this every few seconds until the times when the boiler is supposed to be on and then it clicks on just fine. I am not sure what it is doing and whether this is the only way it can check the time, but if this is a fault that anybody recognises I would appreciate a hand!

Many thanks.
