Hi guys
Last week I went to a job were the customer had a wireless honeywell system in place , I located a fault to the relay box with a burnt out board so changed that and hey presto everything was working
Today she called me up because she couldn't get the boiler working so I popped round the controller honeywell st9400c was boiling on the left side however when I turned it on constant to get the heating on...nothing , the hot tap works fine and boiler fires up which also brought the heating on? At first thought of the diverter valve but it seems ok , the stat which I can't remember the model but it's got a manual dial on the side needs to be turned onto max(30) to switch the relay on
I'm thinking it may be the control box but thought I'd pass it out for help , discussions and opinions
