Evening guys.
So today's job has left me a little puzzled.
Hands up I'm not a heating engine, normally on Commercial and haven't done a Y Plan for some hours!!
Friend asked me to have a look at one of his rentals which had been fine and the boiler guy came to service his WBosch but it wouldn't run.
When I went yesterday the house was at 30+ oC even tho the stat was set to 15.
(The stat and programmer are cheap tat ) Tried to turn off at programmer but did not respond and boiler kept running so switched off at FCU.
Went back today and turned on. Digital display on the Pump head just flashed and nothing responded. Phoned Grundfos tech line and said the pump had packed up needs replacing (I guess this could be as it had possibly been running over a week since the boiler guy had been) Id also noticed the motor valve wasn't responding when call for heat.
Picked up replacement for both and replaced and everything now responding as it should, except the boiler is not firing. Working around the programmers limitations I get 230 at the correct terminal for demand and satisfied on the 3port valve when programmer and stat are calling /not.
So I'm running out of ideas, other than get the boiler guy back.......
