Non-Programmable SimpleComfort Heat Only Thermostat (w/o Fan Switch) - Single Stage

I bought a brand new 2018 Winnabago Micro Minnie. The Atwood supplied thermostat for the furnace (only) required a 3ft pry bar to move the switch from on to off.. and vice versa. Needless to say, the thin plastic lever broke. Reading on RV forums, they all break. How long has Atwood/Dometic been making these? 10 years, 20? 30? Yet, they keep pumping them out without solving the problem. I searched for a solution. Read RV forums for days. Lotsa advice for those people with huge RV'S with heat and AC controlled thermostats.. None for people like me. I found this Simple Comfort Heat only thermostat from Supply House. It digitally displays ambient temp with a back light. Simple controls to increase or decrease temp. Most importantly, an on-off switch that doesnt require a sledge hammer and a block of wood to move!!! Super Fast shipping ! Excellent communication (Order received, order shipped, tracking) 2 screws to remove the old, 2 screws to remove the red wire and whote wire, 2 screws to install the new Simple Comfort thermostat, 2 screws to secure the wires into clearly marked terminals, indtall the batteries (supplied), I'm informed its 64F in my little 18 ft camper, set the temperature to 70F, move (effortlessly) the switch to ON and immediately.. The furnace kicked on. Now, we dont need an old fashioned, hard to read thermometer on the wall! I compared the reading, side by side with our 8 month old super dooper high tech Trane thermostat and there was a one degree diffetence. Im very happy!!

This is a nice basic thermostat. But the differential or swing specs are either misleading or not stated accurately. The specs say the diff can be set between 1 and 5 degrees. But that is not true. When set to the minimum of 1 degree, the swing is actually 2 degrees,1 degree either side of the set temperature.This is not nearly tight enough for many applications, including my steam system. It resulted in huge overshoots.
