If your Honeywell T4 thermostat is blinking heat, it's often a sign that the system is temporarily locked to protect the compressor in your heating unit. This is a standard procedure following a power outage or when switching modes from cool to heat. Generally, the blinking should stop after a few minutes, indicating the lockout period has ended, and the system should resume normal operation. If the issue persists beyond this period, consulting the user manual for troubleshooting steps or contacting a professional for assistance is recommended.
