        Comments about Honeywell® Round Heat Only Mecury Free Thermostat:

        Tried 3 of these --- none worked. Contacted Honeywell help line. They said I must be getting thermostats from a "bad batch" - told me to go to a different store for one. I did get a different one - a different brand - & it worked immediately!!!! So much for Honeywell quality!

        Best Uses

          Comments about Honeywell® Round Heat Only Mecury Free Thermostat:

          Honeywell's old "heat only" mercury tstats tracked better and lasted for decades. This electronic replacement version is pricey and doesn't perform or last anywhere as well. I have purchased several of these units and some track well and some don't. Some have quit working after 2 years of use. Honeywell is not that repair or replacement friendly either.

            Comments about Honeywell® Round Heat Only Mecury Free Thermostat:

            The thermostat was installed to control a pellet stove supplying heat to the second story of a cabin. It works but the lower dial that tracks room temperature reads low. I checked it against a separate thermometer.
