If you are wanting to control the A/C from downstairs, you will need to get a remote thermostat unit, that uses the Main unit, which would be upstairs. For the Radiant baseboards, if they are 240 vAC, you cannot use a conventional thermostat with them and also control the A/C.
You can get programmable 240 vAC thermostats, but it would be best to work with a local contractor that can get them at a better price then you can, and set them up to perform properly. Same with setting up a dual thermostat setup, to control the A/C from Downstairs.
