What he said is correct.. Power extended kit “PEK” if missing a common wire. sometimes on older systems they don’t have a common and this is used instead of having to run a new thermostat wire using a thermostat that powered by the furnace. They provide you with the kit instead of having to purchase one.
Smart thermostats are very good 👍
Ecobee are not bad better than nest IMO

Ecobee power extender, used if you need a common but don't have the wire.

Mercury thermostats are definitely the best as long as you don't break it.
