Electrical Faults

• Loose Wiring: Check if the wires connected to the thermostat are loose or disconnected. Tighten any loose wires and ensure they are securely connected to the terminals.
• Power Outage: A power outage can cause the thermostat to reset. Check if there has been a recent power outage and reset the thermostat manually.
• Faulty Transformer: If the transformer that supplies power to the thermostat is faulty, it can cause the thermostat to reset repeatedly. Contact a qualified electrician to replace the transformer.

Programming Errors

• Incorrect Settings: Ensure that the thermostat is programmed correctly with the desired temperature and schedule. Incorrect settings can cause the thermostat to reset to default values.
• Software Glitch: Sometimes, a software glitch can cause the thermostat to reset. Try resetting the thermostat to factory defaults and reprogramming it.

Mechanical Issues

• Dirty Thermostat: Dirt and dust can accumulate on the thermostat’s sensors and components, causing it to malfunction. Clean the thermostat regularly to prevent this issue.
• Faulty Display: If the thermostat’s display is not working properly, it may cause the thermostat to reset. Contact the manufacturer for a replacement display.
