What Experts Agree On
What Experts Love
- ✓ Handles up to 3H/2C heat-pump staging, enough for a 2-stage geothermal compressor plus one resistive aux stage, and exposes every parameter through the installer ISU menu instead of an app wizard.
- ✓ Aux Heat Lockout defaults to Off, which Honeywell documents as the correct starting point for geothermal, then lets you set an outdoor-temperature ceiling above which the backup coil cannot run.
- ✓ Compressor-protection minimum off-time and adjustable cycle rate are set in the ISU, so a tech can tune short-cycle protection precisely to a given ground-loop unit.
- ✓ At about $155 with a 5-year warranty it is the installer-favorite wiring-flexible option, supporting both O and B reversing-valve geo configurations.
Common Criticisms
- ✗ Tops out at 3 heat stages, so it cannot drive a geo system that uses two separate banks of auxiliary resistive heat.
- ✗ The ISU-driven setup is unfriendly to first-time DIYers and the app trails ecobee and Nest on polish and runtime reporting.
