Can I use the Smart Room Sensor with a zoned HVAC system?
FAQ , Thermostats , Troubleshooting Modified: March 19, 2026
No. The SRS is not compatible with a zoned system such as iHarmony. The smart room sensors work only with the S40. Any temperature balancing that occurs between the S40 and the smart room sensors may be in direct conflict with calls for air from the zone sensors and their respective zones. The smart room sensors are appropriate for households that do not have zoning equipment installed. The SRS is compatible with dual and single split HVAC systems that are not zoned.
