Installing Tado over a Potterton 5100583 PRT100ST2 thermostat


I am attempting to self install my Tado thermostat. Having removed the cover I am presented with the following S(see attached screenshot). The Tado guide says label the wires and connect wire 2, 1 and 4. On my unit I have no wire in terminal 1. Any help would be welcomed. Thanks
