February 9, 2017 – Health Canada has further expanded a recall (which commenced back in January 2011) involving certain line-voltage thermostats that may overheat, emit smoke and damage the wall, posing a fire hazard to consumers.

The recall involves certain Garrison, Maison, NOMA, RONA and UPM line voltage-thermostats with the following serial numbers:

• HTM211
• HTM311
• HTM511
• HTM611
• HTM621

Note: some thermostat model numbers may have a letter after them (e.g. HTM221A). This letter indicates a minor, non-electrical variation in the product, such as the shape of the LCD window, or buttons or the colour of the unit. These letters do not affect the serial numbers included in the recall.

The recalled units were certified to CSA 185066. (Also note: certain THM211 and THM311 models were recalled in 2002 by CSA Group and Ontario’s Electrical Safety Authority.)

Between June 2011 and February 2017, Health Canada says it has received 51 reports of incidents from consumers and retailers regarding the use of these thermostats, including overheating, melting, smoke and damage to the wall. No injuries have been reported.

The number of units sold to consumers is unknown; however, the thermostats were known to be sold at Canadian Tire, RONA and various other hardware and building stores.

Consumers should immediately stop using the recalled thermostats and contact the retailer from whom they purchased the product.

Manufactured in China, the units were imported by UPM Marketing Inc., which is no longer in business.
