- Display and usability: A large or backlit display helps readability, especially in dim rooms or older homes.
- Reminders and alerts: Some models offer air filter reminders and display settings to fit your decor.
- Installation considerations: Check base compatibility, wiring (2-5 wires presumed in many models), and compatibility with existing plates for a smooth upgrade.
- Future upgrades: If you plan to upgrade to a heat pump or more complex systems, choose a model that supports those configurations.
Frequently Asked Questions
