Thermostat replacement alternative..

I like this one:

I have them in several campers.

They have a separate fan switch should you want to wire up a basement fan, etc.

It would need to be heat and ac plus 2 speed for both.

Depends what you want to use it for.
I bought a house 2 years ago with 4 AC zones.
So when I put 2 of WI-FI thermostat in main areas, for guest quarters I did not want to worry about batteries and computer reset, so those fit the bill.
They have been around like 100 years.
Funny I paid $13 for each 2 years ago, now they are $35 on Amazon.
Must be I am not the only 1 who likes them.

In which case another LuxPro thermostat works well. It can be installed horizontally or vertically and has a simple interface with easy-to-read numbers:

I like these because they have been reliable from 0 deg F to 120 deg F, the batteries have a very long life, the numbers are easy to read at a glance, and they have backlit displays.

It can be operated with 2 AA cells (24v not necessary), which is convenient for RV use. Switching is relay based.

The thermostat I pictured above operates with no power and that is what I like about it most.
But no household thermostat will have 2-speed, so coming to the option, this is thermostat I have in my 2002 Fleetwood.
Almost 20 yo and still operates like a charm.

I soaked the slider switch with wd40..
It seems to be making contact now and is working again..
To much salt air!

Good to hear.
But how you adjust fan speed on it?
I don't see any switch for it?
