My heating control unit (horstmann channel plus h37xl) currently has no display. The boiler isn't highlighting any issues and the fcu seems to be functioning, therefore it doesn't appear to be a fuse issue.
Can anyone help? No heating or hot water without it and not sure what to do next.
Had to get the control unit itself replaced. The elec couldn't figure out why it stopped working. Good to have heat and hot water back. Thanks again for your help Leo.
No problem Tiv, glad you're back up and running. Most of these control panels aren't repairable, at least economically anyway, so replacement is usually best.
