What Does Nest Thermostat Delayed Mean?

The “Delayed” message on a Google Nest thermostat typically indicates a power interruption and restoration. This message appears when the thermostat detects a disruption in the power supply, which could be due to various reasons such as a power outage, a temporary loss of connection, or issues with the HVAC (heating, ventilation, and air conditioning) system. It is a normal part of the Nest thermostat’s operation to protect your HVAC system and ensure it functions safely. Once power is stabilized, the thermostat will resume its normal operation, and the “Delayed” message should disappear on its own.
