The company’s comments, in its own words

(3/26/2019) Lux Products Corporation: LUX Products (“LUX”), now part of Johnson Controls, takes potential product safety issues very seriously and routinely monitors consumer reports and other relevant information, including through saferproducts.gov. The product that is the subject of this report meets or exceeds the US Government and Industry Safety Standard requirements (i.e. CAN/CSA-E730-1, UL-60730-1A, CAN/CSA-E730-2-9, UL-60730-2-9, etc.) as noted in our agency listings.
In the incident report, the consumer noted that wires had melted and odor was detected and the thermostat was warm to touch. LUX has seen occasional failures and warranty claims on reported failures that are similar in nature to this incident, however, based on root cause analysis and subsequent site inspections, they were attributed to improper electrical connections or installation conditions and not to defects in either the product design or manufacturing.
LUX does not believe this is a safety hazard specific to the unit, as the unit’s wiring and plastic housing conform to UL requirements for flammability resistance of plastic parts. In regards to installation, the LUX thermostat notes in the Model #ELV4d installation instructions specific compatibility restrictions regarding line voltages and amps, as well as service equipment max heating wattages and motor HP ratings, etc. Additionally, the instructions note warnings specific to who should install the unit, as well as required circuit protection. In the incident report, the consumer did not note any specifics regarding the product installation, service equipment controlled by the thermostat, or other pertinent factors related to the product’s installation and use, as noted in the instructions.
At this time, an accurate root cause analysis is not possible without added information or the availability of the part. The consumer has reached out to our technical support department, and LUX is in process of coordinating the return of the unit for further inspection, as well as obtaining additional information that may help in identifying potential root cause.
LUX is committed to providing safe products to consumers and, therefore, invites this consumer—and any other consumer with a safety concern regarding one of its products—to contact LUX call center toll free, at (856) 234-8803 or email to TechSupport@LuxProducts.com.

The product, in the report: LUX programable thermostat PSP511La

On 12/21/2011 the Norwich Fire Dept responded to an alarm at the [REDACTED] in Norwich, NY. A heat sensor on our alarm system triggered the alarm. The room temperature according to the fire dept was 125 degrees. It turns out that the termostat had held the furnace on without shutting off. Upon close examination I saw that a low battery indicator was flashing.. No beep or other signal to advise us. This is a dangerous situation and without the alarm system the fire dept said we might have lost the building. I think this might be a matter for a recall by the consumer protection agency. [REDACTED] I arrived on the scene just moments after the fire department had entered the building. They had a lock box to allow emergency entry. They informed me that one furnace failed to shut down. I located the thermostat and shut it off disengaging the furnace infront of members of the Norwich Fire Department, Norwich, NY. The LUX company has been very accomidating during this period and has offered to pay for expenses involved with the incident. They have requested the return of the thermostat and batteries in use at the time for non destructive testing. Subsequent to this information...the manufactuer has sent 2 new thermostats to us to replace the one which malfunctioned in the studio.
