What to know before buying
Listing details to confirm
The listing is inconsistent about controls and connectivity: it identifies the product as a wired, push-button thermostat but also lists Touch and Wi-Fi. It also gives a 3.5-inch screen and lcd or led display details that are not reconciled with the stated T3 wired identity. Confirm the exact model, control interface and system compatibility before purchase. Battery lifespan and broad system compatibility are manufacturer claims, not independently verified.
