The infinity is what is considered a communicating thermostat.2 terminals are used to supply voltage to thermostat and the other two are used as a data link for thermostat,indoor and outdoor to communicate.

The TP-PAC01 is a standard non communicating thermostat which simply operates through the terminals Y,G,W,O C etc to tell equipment what to do and is not designed for use with the Infinity system

According to Carrier supplier the DIP switches can be adjusted to allow this unit to function do you want to re-think this
HVAC Technician: airheatman, HVAC Technician replied 2 years ago

Not a problem, If the equipment says it can use a conventional thermostat(Some can and some cannot), and you want to give up the capabilities of the communicating sytem I will be happy to guide.

First of all go to the air handler and the outdoor unit and we will remove the interface module or adapter convert this to conventional.

Also give me model on outdoor so I can guide accurately.

It's covered with snow it will take awhile. But I'll get it
HVAC Technician: airheatman, HVAC Technician replied 2 years ago

Just spoke with Carrier rep and he informed me the thermostat can be used as communicating if you have correct interface module.Do you know model on your interface module at furnace?
