I took a job off my mate the other evening,,wish i hadnt !!!!
85 year old engineer wanted to replace his single channel programmer and put a 2 chan in
well he got in a muddle with his wiring hence the call
it looked straight forward so went up to the immersion heater and notice its a 3 port Y plan system
odd i thought house about 30 years old should have a 2 chan in anyway (alarm bells didnt ring)
took face plate off a 2 gang box to find its wired for single chan......
single chan back on back the next day
rip it to bits and start again for a 2 chan
test the programmer
hot water fine
heating was fine for a while then stopped working when selected
wiring must be fine but double checked
took the heating wire to the valve and put it in the cylinder stat output
works fine
put it back and call for heat
240v into valve nothing out on the orange
disconnect orange 60v ??
reconnect output on orange nothing 0v
scratching my head call my plumber and thinks it may be valve
swap it same fault
the old boy is puling his hair out as to why it isnt working.....he went off on one,,,,,,,,his wife calls the son
explain to him and suggest there was a fault initially on the build which the couldnt be bothered to find so put in a single chan.
what do you want me to do now revert to single chan or fault find from scratch ???
put it back to single channel on the new programmer
gave it one more go before removing cylinder stat and works fine for about 5 mins
then the heating stops calling
now from this i am of the thinking something is breaking down any ideas
pump /stats/valve all ok
only thing i didnt do was use a heating wiring centre as he didnt want the extra cost !!!! wish i had forced it on him
as it stands ive been paid to date he (being an engineer) is drawing his own circuit diagram and may get me back next week
he is one of the guys who wants to help all the time pain
any thoughts guys ???
