hi dunny this is very common with with the tuscan controller used on a synopsis network in sainsburys i wouldnt worry about it i have had a display in a sainsburys in scotland flash that message for the last 3 years and the room works a treat

if it's a square display with 4 buttons just press the last button to clear it or just turn the case off then on.The c flashing then temp,has been caused by someone messing about with the controller,it's just away to check the temp when on defrost or when the case is alarming.

Yes it has 4buttons on.i pressed the last button and it stopped for about 5seconds.Then started again.i didnt try switching it off,i will try that in the morning.thanks

One thing with the Tuscan controler is that they do respond well to being turned off. For a multitude of minor, niggly faults a simple power off on on cures all.

Check the display buttons, I've had them stick in the past. Can cause all sorts of issues!!

Did you know you can put on fans only by holding esc and enter down, will cycle through case off light only fans only and back to normal, this sometimes stops it c ing. you can set parameters with the 4 buttons too but can't remember how, usually use handset. also RDM controllers will work directly on elm network which is good as elm are obsolete!!

You can also raise and lower automatic night blinds using the display keys!

hi chilled the elm/honeywell range is not obsolete maxey moverly bought the range and fully support it they also do tech support and offer on site support as well.

So they do, was with Yag only the other week. all recon stuff though. make sure chip numbers match or networks don't like it, especially ST boards in js.
