Hello Sparky62,
Thank you for reaching out and bringing your concern to our attention regarding the unexpected behavior of your heating system despite setting the Nest Thermostat to a lower temperature. Let's sort this out.
There could be a few reasons why your heating is still turning on.
- Make sure that the Nest Thermostat is set to the right mode (heating or cooling) and that it's not in the "Heat-Cool" mode, which could be causing conflicting signals.
- Check if there are any scheduled changes or learning adjustments that the thermostat might be making automatically. The Nest Learning Thermostat adapts to your preferences over time, so it's possible that it is adjusting the temperature based on its learning patterns.
- If you have additional room sensors, check if they are placed appropriately and are not detecting unusual temperatures. Sometimes, a sensor in a warmer location could trigger the heating system.
Let us know if you need more help.
Best regards,
Mark
