Good morning. I got 230v on brown wire.

Multimeter reading i meant

Within the thermostat unit itself? Yes. It clicks but there is no difference in reading (at least how I do it) before and after (no heat demand / heat demand)

As in the reading stays at 1.

Ha ha. Oh dear. Yes, the markings on the plate confused me. In any case - I got the same result testing the real A and B now..

Just to clarify - the unit was calling for heat (requested temperature being higher than room temperature)

OK, so it's definitely wrong. Not sure how I got the varying reading yesteday but today it stays at 1 when testing for resistance and no beep when testing for continuity.. And yes, I did all the test on a disconnected (but battery powered) unit.

I had a chance to test it with a multimeter. When I use continuity test I get no beep... But when I use resistance test it starts with negative and goes up to almost 2k positive (sorry if it sounds dumb but as I said it's new to me). Does it mean it's faulty?...

Hi John, I meant that it doesn't do it based on the temperature of the environment but only when I manually set moved the dial to 25 degrees. Hope that clarifies it. Thank you

Hi, Yes, T4 is programmable. How do you mean that it is supplied by the original programme? I will check for 230V at L later in the week and report back. Thank you.

Hi, As I mentioned I have the boiler's programmer set to constant. I have raised the temperature on the T4 thermostat to 35 degrees and it had a flame icon on (calling for heat) but nothing happened. Thank you.

Good observation. However, as T6360B only started the boiler (and didn't function as a thermostat) I thought cables (or the way they are connected are at fault. How can I check for continuity? (sorry, I'm not that experienced with DIY) Thank you.

Thank you for your reply Ian. It is a non-wireless model. To simplify my confusing sentence : 1. I have replaced t6360b with t4 2.T4 could not start the boiler 3. I have replaced t4 back with t6360b as it's cold outside and I need the boiler running. I will try your idea (probably only later...

Hi I wanted to ask your advise, in case I missed something obvious, before I call someone in. We have moved in to a new place, which had a Honeywell t6360b (and combi-boiler Main 24 HE) installed. The problem from the get go was that t6360b was useless as a thermostat and functioning only as a...
