Hi
I don't if anyone can help with this one.
I have just replaced a very old beige Honeywell Mechanical themostat with a shinny new Honeywell T6360B.
The problem is that when the programmer (potterton EP2002) is off the heating will still come on this seems to be the thermostat telling it to aswhen you reduce the temperature it the boiler goes off.
When the last thermostat was installed the programmer did its job.
The bit I am not sure about is have I wired the new thermostat up correctly.
I have three wires Blue Red and Yellow.
I assume red is Live, Blue Neutral and Yellow switch Neutral (I think)
the thermostate is wired 1 = red 2 = Blue and 3= Yellow.
I have tested voltage and there seems to be 230v on 1 and 2 when thermostate is low. Also there is 230v on on 1 and 2 even when CH is switched off at Timer is this correct?
Is this correct as the installation instructions are rubbish.
The boiler I have is a Worcester Greenstar 18ri ( condensing not Combi). Fitted with Honeywell 3 way valve.
Thanks in advanced for any help
