Thermostat frequently displays "Waiting" or delay before starting equipment

Safety first: No wiring changes are required; this is usually normal behavior.

Steps to troubleshoot:

• 1. Understand delay: Emerson smart thermostats often include a 3–5 minute delay to protect compressors from short cycling. This is normal after power loss or mode changes.
• 2. Avoid rapid changes: Do not repeatedly change modes or large setpoint swings; allow the system to complete cycles.
• 3. Check configuration: In advanced settings, verify that any additional delay settings are appropriate for your system.
• 4. Monitor behavior: If delays are always the same length and occur after power or mode changes, they are likely normal.

When to call a professional: If delays are excessively long (e.g., 15+ minutes) or equipment never starts, an HVAC technician should inspect the system.
