"Not stated by the maker" means the maker's pages do not say; this shelf leaves it blank rather than guess.

Know before you buy

The resideo.com product page carries a "*C-wire Required" footnote, but it is attached to the Wi-Fi upgrade path, not this model; the installation guide says the C terminal is optional if batteries are installed.
