Thermostat shows 'Aux Heat' or 'Emergency Heat' running too often on a heat pump system, increasing energy use.

Safety first: No high‑voltage work is required for configuration changes.

• Step 1 – Review aux heat settings: In the thermostat equipment or heat pump settings, check the Aux Heat Lockout or Balance Point temperature and adjust lower if appropriate for your climate.
• Step 2 – Verify outdoor sensor: If using an outdoor sensor, ensure it is reading correctly. Replace if readings are inaccurate.
• Step 3 – Adjust staging behavior: If available, adjust staging or comfort vs. savings settings to reduce reliance on aux heat.
• Step 4 – Monitor performance: After changes, monitor aux heat usage over several days in the Geo app energy reports.
