[QUOTE="Doc Hudson, post: 176794, member: 1607"] I was just pointing out that hoppy needs to be aware that not all thermostats can work in every application, a few variations exists. Some require power supply to operate an internal relay, typically 12v or 24v. Some use 230v at the contacts control internal ballast heating resistor and illuminate an indicator light. Some are battery controlled that just switch dry contacts. As we don't know what type of boiler it is, best to make hoppy aware of some possibilities. Doc H. [/QUOTE]
