Also unless managers in grocery store chains means something else than in any other corporation, I somehow doubt it's managers who monitor or "take action" on remotely-controlled fridges.
Some supermarkets in the US (and maybe other places, but can’t speak on those) give department-level managers control over the fridge temps in their department, as well as task them with routine monitoring. From my experience, they do generally have remote assess for both reading current temps and adjusting them, since decisions on where to put certain product (with various temperature requirements) are often made on the fly.
So that's more of an operational role than managerial, at least in corporate terms? I don't have much experience with role requirements in retail, but I imagined it's closer to small-scale manufacturing, where "supervising/controlling the machines" and "managerial duties" would be distinct roles with distinct job titles.
