Cheers. Just tried that out and the CH sensor now reads 1.28k. Swapping them over is what I do to trick it into heating up. If I do that and turn on a tap, the boiler cuts out. As for the chattering relay, I don't know. It's the same click it makes when it's about to fire up the boiler...

As for the sensors. How simple are they to replace? Looks like the part is a 386818 / 800310 Ferroli thermistor. As I say, I'm no plumber and I'm not keen on messing where water can leak, but I'm okay with electrical things and parts that are simple to replace. However, I'm not sure how...

Okay, assuming I'm using this meter right... When the boiler is cold CH sensor = 1k DHW sensor = 0.97k

Actually yeah, thinking about it, it should be that simple. I just wondered if there were special tools required. I'll dig out the meter and wait for the system to go cold.

Sounds like a job for BG or someone then unless this is something I can do myself (as simple as using a multimeter?)? I'm no plumber/heating-guy but do like to know how things work. To be honest, when they do a so called "service", they seem to do little more that just look at the thing. Had a...

Okay, I've had this problem for years and never really got anyone to fix it. First up, the boiler: Industrie Fer Hawk II, combination boiler (instructions are on their web site for download, as that's where I got them). Boiler is some 10 to 15 years old I think. It was there when I bought the...

The 2A is the one on the PCB which I would have thought is just for the PCB. The 230V terminals for a roomstat connection appear to be the mains input connection and outside of the 2A protection. But I don't claim to be an expert by any means. If it's 2A max then that may be fine anyway by...

Hi, Just purchased an RF room thermostat kit to fit to my combi boiler, and not quite sure on the fusing involved. The RF receiver connects to the 230V and 24V roomstat terminals on the boiler which I've identified in the boiler instructions, which is fine. However the receiver...
