Is their a thermostat that works with Smarttings? Simple heat only with and in floor temp sensor. Not electric has to be for gas.
Honeywell has a Zwave thermostat that you can run in heat only mode with hydronic setups. Supports other accessories if you have them (humidifiers, AC, etc)
I don’t think that will do exactly what I want. It does have a terminal for a temp sensor but it looks like that is for another zone. I need it to monitor room plus slab temp at the same time to control heat in one room. So if the room is suddenly cold from a door opening it does not run the heat if the slab is already warm.
