Should a fuse be placed on the AC power input to the JLD-612 controller? If yes, what value is recommended? My application will be powered by 120VAC 60Hz.

It is going to depend on what the wattage is of your heater. Divide the wattage by 100 to get an approximate current requirement and add a few amps to get to a common fuse size. I use a 15A fuse for a 1000 watt heater and 20A for a 1500 watt heater.
