The PRO1 IAQ T705 is a straightforward, single-stage thermostat built for reliability. It comes from a brand that focuses on core HVAC controls, not smart-home gimmicks. This is a tool for consistent comfort and predictable energy savings, backed by a solid five-year warranty when you register it.

Programming the T705 is simple. You use tactile push buttons to set separate schedules for weekdays and weekends. The gray digital display is clear, and the logic is intuitive after a few minutes of setup. Over 245 customer reviews consistently note that it does its job well—it maintains your chosen temperatures without fuss. It handles one heating and one cooling system, making it a direct replacement for many older, non-programmable models.

The trade-off for this simplicity is a lack of modern connectivity. You won’t adjust it from your phone or get usage reports. For a no-frills, set-it-and-forget-it upgrade to a basic thermostat, however, the T705 delivers exactly what it promises.
