Do you have access to a multimeter? -- Ian
OK first check - with the multimeter set to volts ac and range at 250 v or above tell me if you have got a voltage between the in side of the thermostat and the casing?
OK follow the input cable back and you will see it goes to a selector switch - check if you have any output from the selector switch?
Good to hear, would you now kindly rate the information given by selecting from the star rating system at the top of the page, once done you can come back to me at any time if you need further help but it allows me to clear the job off my screen. thanks for using JA and have a good evening - Ian
