What to know before buying

Listing details to confirm

The listing's connection details are inconsistent: it describes the thermostat as wired with a two-wire installation, while another field lists BACnet MS/TP under a wireless-connection label. Confirm the intended connection and compatibility with your heating system before purchase. The listed dimensions are also unusually large for a room thermostat, so verify them against the product documentation. The instruction language is unconfirmed, and the listing says English is not guaranteed.
