All 3 are the same type from Honeywell, the reason for using the same kind
was that it had a plug in application
and no need to rewire, but if I have to replace the thermostat every
season,
I will try a different route.
thanks to all for the help

Change to a different model of Honeywell or Robertshaw.

The first model of the digital round (T8700) had a failure, looks like the
second model does too. :-(

I've had good results with the following series of stats...

Honeywell
FocusPro 5000
FocusPro 6000
VisionPro 8000

Robertshaw
9400's
9500's
9600's

There are many stats from these categories to meet your needs.
