Description
The Suuwer S721 non-programmable heat pump thermostat is suitable for home use, accommodating up to 2 heating and 1 cooling multi-stage systems. It supports both heat pump systems with auxiliary heat and those without, as well as most 24V conventional heating systems. Dual-powered by 24VAC or 2 AAA batteries, it typically does not need a common wire (c-wire), enhancing its compatibility. However, buyers should review installation instructions thoroughly before purchasing, especially if they lack prior experience, to avoid compatibility issues.
