The batteries in your Inspire Home Automation thermostat should typically last more than one year, depending on how frequently the thermostat is used.
Battery life can vary based on factors such as:
How often the display is activated.
The type and quality of batteries installed.
For the best performance, always use high-quality alkaline batteries. Avoid using Heavy Duty, NiMH, or NiCd rechargeable batteries, as these are not recommended.
If your thermostat displays a low battery warning or the display becomes dim or unresponsive, replace the batteries with a fresh set of alkaline batteries.
