Installation Notes

Coin cell batteries are replaced by electricians, HVAC technicians, and general trade personnel as part of routine device maintenance. Before replacing a battery in any thermostat, sensor, or security device, follow the device manufacturer's shutdown or memory-save procedure to avoid losing programmed settings. Use non-conductive tools when handling coin cells in tight battery trays to prevent accidental short-circuiting. Dispose of used lithium cells in accordance with local regulations — do not incinerate or puncture.
