Lux Products engineers and tests its products for the highest quality, worry-free performance.
However, variations in battery quality could impact the performance of your Lux thermostat.
For thermostats which require batteries to operate, failure or sub-standard performance of the batteries may impair or prevent the correct operation of the thermostat. Use Duracel® or Energizer® alkaline batteries ONLY for all Lux® thermostats requiring batteries. BE SURE TO CHANGE THE BATTERIES AT LEAST ONCE A YEAR.
