Thermostats with a built-in ground fault circuit interrupter, or GFCI, and designed for use in under-floor heating systems have been recalled over a risk of electric shocks. The thermostats are connected to 208-volt or 240-volt power supplies. Their floor sensors can be damaged by cutting, drilling or nailing – posing a shock risk if the power supply is not disconnected.

The thermostats, made in Denmark, are sold under the brand names Britech, Copal, Danfoss, Momento, OJ Microline, Warmly Yours, Raychem and True Comfort. About 13,000 of the thermostats were distributed in Canada at home improvement stores, tile shops and other retailers between January 2000 and December 2008.

There have been no reports of injury, according to Health Canada.

Consumers are advised to not cut, drill or nail into the heated floor. They are urged to contact OJ Electronics to arrange for a free in-home repair.
