Thank you for the help! I have a 4-year-old Jotul GF500 LP gas direct vent stove that I've been very happy with until having problems w/the "Smart" thermostat setting intermittently not working this past late winter/early spring. I figured I'd better give things a try, seeing as how the new heating season isn't far off, so I tried to get things going this AM.
I found there was not even a thermostat icon on my remote when I went to use it! Luckily I followed the instructions here to pull one battery, hold the thermostat button, and replace the battery. That got my icon back.
Then I set it up to run "Smart", and it turned on and off as it should. However, I noticed that now the "on" and "off" thermostat functions are opposite of what the remote says! If I turn it to "on", it will shut off. If I turn it to "off", it turns on. I can live with this, not the end of the world, but wonder if anyone has experience w/this?
Also would welcome any ideas about intermittent failure of "Smart" function. It does not seem to be related to new/old battery issues, as the battery icon was not displayed during any of the failures. It has failed at both the upper and lower limit, failing to turn ON as well as failing to turn OFF. This stove is the only heat for my home (not a cabin or vacation home but a 24/7 regular old house!), and thus it is a big deal if the thermostat doesn't work. Again, this is an intermittent issue, not a consistent thing.
My stove plugs into the wall, and thus I don't think the advice about batteries in the receiving unit would apply, would it? Hard to believe that if they were there, that they would have lasted 4 years when the remote has required replacement numerous times over that time period.
Thanks in advance for your help.
