Had me tearing my ****ing hair out today this! Im not the best on the wiring side as it is especially when some **** has been before me and wired it in like a school boy!
Went to a breakdown today, no heating no hot water. Figured the diverter actuator was knackered! Fits a new one wired in the same switches it on for heating/hot water all fine! Switches the room stat off and clock over to water only and nothing! Checks the cylinder stat, common to 1 common to 2 for continuity etc all fine! Goes back over my wiring making sure it was ok still nothing! Changes the randal 102 still the same so now I'm getting ****ed! Turns the heating/hot water back on and it's all working! This time I never turned the room stat down and switched the clock over to hot water and the bloody thing worked!
So it turned out the system had been wired in so the room stat had to be turned up for the hot water to work! Then I thought about the cylinder overheating, so I tested the cylinder stat turns that down and the system stopped! So both cylinder stat and room stat controlled the hot water! Going to have to go back tomorrow to re wire it from scratch!
Anyone any ideas as to what the hell they have done here cause I couldnt figure it out!
