Thermostats

ColdHouse

I have four zones in my radiant floor heating system. Over the past twenty some years, most of the thermostats have been replaced, so its a mishmash of brands. My question - is there a preferred swing when using on radiant heating system? Mine seem to be three degrees. Set at 68, on at 67 and off at 69, which seems to be too wide a swing. Also, what are some more reliable thermostats brands, if such a thing exists anymore.

how many wires do you have at the station location?

I like the Ecobee brand, it has an adjustable range. But to tight will cause some on off cycling perhaps. I set mine to 2 degrees

@hot_rod “how many wires do you have at the station location?”

I will double check the number of wires run to each zone. I know it is only using two wires to pull in a relay running each circulator.
