Eventful Day - Uneventful Blip

This, sadly is the only picture I too today. Got back tonight from Ipswich and found I had not heating or hot water.
The "whack it and see" effect was used as these control units are a common problem on Potterton boilers. Took a pic for reference and location of wires. Easy Peasy.
Heating and hot water back on - Yipee.
