Hi Joe, I'm Brian and I'm here to help!

Yes, you need a thermostat to control that unit. It can be unit mounted or wall mounted remotely. You need a pilot duty low voltage thermostat and it will connect to terminals 4 and 5 with terminal 4 being the "R" terminal and terminal 5 being the "W" terminal. A standard heating only or heating/cooling thermostat like you would use on a home ac/heating system will work fine. Your unit heater also has the option to run the unit heater's fan independently. If you want that function you would need a thermostat with a Fan Auto/On switch and the G terminal on the thermostat would wire to terminal 6 on the unit heater.
