Almost certainly it's something that can be replaced with just about any
simple household thermostat.  Just make sure you use one without any
fancy electronic features.  Basic thermostats are just a switch, there
isn't any kind of active electronics inside.  (In fact, generally
they're switching a low-voltage control circuit from the furnace,
usually 24 volts AC.)

The only caution I can think of right now is that some thermostats use a
mercury switch.  (Or used to, anyway; that may have been discontinued
for environmental reasons.)  If you park off-level their temperature
accuracy will be compromised, though they should still work otherwise.
