Thermostat that holds temperature more constant...

The Emerson thermostat for the propane heater that came with our Scamp would heat too much before turning off the heat.  Testing showed that there was a huge delay (as in a time constant type of dampening) built into the displayed temperature.  The small Scamp interior would heat up 5+ degrees beyond the indicated temperature before the Emerson even showed a 1 degree rise.

The solution was to install a similar thermostat, a Honeywell TH1100DV1000.  Cost was about $25.  Size and mounting holes are the same, the only difference is that the wiring enters on the left side instead of the right.  That's easily remedied with a Dremel tool, or similar.  The new Honeywell is programmable in terms of how tight it holds the set temperature, the tightest setting is 6 CPH and that's where I set it.  Temperature control is far better now, and furnace run-times are much shorter!

We too had the same issue with our 2019 13 and reverted all the way back to an old school mechanical  T Stat with a anticipator adjustment and at the most sensitive setting it is tremendous better. The Electronic unit that came was trying to address this but needed more. A better solution would be a smaller furnace BTU but I cant find such a thing. maybe 8-10,000 would be easily enough for 66 square feet

Interesting -- Ours is a 2021

Interesting -- Ours is a 2021 and I was wondering how long this Emerson thermostat has been used, and if they all were as slow to respond. 

The Honeywell replacement holds within about 2 degrees, shutting off with about 1 degree rise followed by another 1 degree rise as the burner shuts off and the fan continues to run for a while.

The unusually slow response of the Emerson is in software rather than the sensor. One test I did was to sit the Emerson (not wired) on the table, run the furnace until the actual temperature changed 4 degrees, the Emerson hadn't changed at all -- Then pop the battery out and back in (reboot), it immediately read 4 degrees higher.
