As I said I did not get an instruction leaflet but I did not realise this at the time because of the sheaf of installation paperwork. The only thing I can see on the display panel is RXI . There is nothing on the room thermostat itself other than the name Danfoss.
Thank you, ***** ***** your help so far. I shall go and see how to detach the thermostat and get the info for you...........Later! Success! I found the screws and discovered it is battery operated. So, problem solved!
Inside I found the following letters and nos.
RET B - RF 087N 727 000
I should have been told about the batteries at the time of installation. So annoying not to have the manual but if I use the above code, will it be easy to get a copy of the manual? Is it ok to put in ordinary AA batteries until I can get the Extra Heavy Duty kind? I don't want to do anything to make matters worse.
Thank you so much for your help, Michael.
I am most impressed with the service.
