How do i wire my new oven thermostat?

My Tricity Bendix SI 530 GR main Oven Thermostat has gone. I have a replacement but the wiring diagram sent with the part is different from the cooker itself. My new Stat (ET5100) differs from the original one (ET46TH). There were 5 connections on the original, Purple wire to terminal 2,yellow wire to terminal 6, beige/cream wire (with Plastic Sheath) to terminal G, Black wire to terminal H, and red wire to termiinal F.
The new stat only has Terminals A,B,and C (B and C being double connections).Please help
