Honeywell STF724 vs. STF72F: What’s the Real Difference?
If you’re comparing Honeywell STF724 and Honeywell STF72F, you’re probably wondering, “What’s the actual difference between these two models?” Both are popular thermostats for HVAC systems, but they cater to slightly different needs. Let’s break down their specs, compatibility, and features in plain English—no jargon, just the facts you need to pick the right one.
Design and Compatibility
The STF724 is a non-programmable thermostat designed for basic heating/cooling systems. It’s straightforward, with a manual switch for heat/off/cool modes. Perfect for folks who want simplicity—no scheduling needed.
The STF72F, on the other hand, adds flexibility. It’s compatible with heat pump systems (with auxiliary heat) and supports multi-stage setups. If your HVAC system is more advanced, this model might be the better fit.
Key Features Compared
- System Support:
- STF724: Works with single-stage conventional systems (gas, electric, or oil).
- STF72F: Handles heat pumps (up to 2 stages) + conventional systems.
- User Interface:
- Both have easy-to-read displays, but the STF72F includes a “Emergency Heat” mode for heat pump users—a big plus in colder climates.
- Installation:
- The STF724 is plug-and-play for basic setups.
- The STF72F requires a C-wire for power if you’re using a heat pump, which might mean extra setup steps.
Which Should You Choose?
- Pick the STF724 if: You have a simple HVAC system and don’t need scheduling or heat pump support.
- Go for the STF72F if: You own a heat pump, need multi-stage control, or want future-proofing for system upgrades.
Final Thoughts
Neither model is “better”—it’s about what fits your . The STF724 keeps things simple, while the STF72F offers advanced features for complex setups.
