Thanks Leezer. Those links are very useful.
I called the local boilere spare store today. They advised me that it was a simple unplug and reconnect process. They never mentioned anything about amending settings!!
I had a look at the pcb. And I no electrician or heating engineer but there don't appear anything that can be adjusted on it, just capacitors and resistors and relay.
I will give the heat exchange a call in the morning. They not too far away.
Appreciate your help.
