Do this thermostat require a c-wire null

Yes it does, or a power adapter kit

Hi Dee! This Amazon Smart Thermostat requires a power source in order for it to function, and the "C" wire provides 24v +/- of AC power to the thermostat for that purpose. If the current thermostat that you're replacing has a "C" wire, then you don't need the adapter. However, If the thermostat you're replacing does not have a "C" wire, then you need to install the adapter. Hope this helps, enjoy your day!
