I THINK SALUS HAVE STOPPED TRADING.
My IT300 Worked great for the first few years then suddenly went haywire. The remote sensor screen is locked and the iPhone app shows room temperature stuck at 24°C. Can’t override it. So no heating.
Phoned their technical support number in Scotland and the number is now used by NHS Scotland. So phoned their head office number in England, this time the phone was answered by a children’s charity. I was told they get lots of phone calls from irate SALUS customers. Just a hunch but could it be SALUS is no longer in business.
