Carrier Comfort Temp Thermostat 140027-03A

[Norton]

The 14 pin LCD chip that shows the day/time of each zone setting is bad. Not
only can't I find any info about the chip, I can't find any info about buying
a new thermostat. It is a 4 zone system and it seems like all that is offered
is a whole new zone controller system at $500.00+ Seems a bit crazy that this
thermostat or a compatible one is not available. Any suggestions, short of
having to buy a whole new controller system?

did you ever get this resolved? I have the same system but my problem is the
rotary dial is not working well anymore. Can't find any replacements.

Tony, I found an old post about your Carrier zone thermostat. Did you resolve this? I am having the same issue with my 27 year old antique. Thanks

Just make sure you get the right type of thermostat for your system:

Raspberry Pi or Arduino should work.
