Dispatched for a thermostat not operating properly after the homeowner replaced the batteries. Upon arrival, a full inspection of the thermostat and related low-voltage control wiring was performed to ensure proper system communication. Testing confirmed the thermostat had failed internally and was no longer sending a reliable call for heating and cooling. Replacement options were reviewed with the homeowner, and approval was given to replace the faulty thermostat. The new thermostat was installed, programmed, and tested. System operation was verified in both heating and cooling modes, and proper response and temperature control were confirmed. The system was operating normally at the time of departure.
