How to connect a three-phase muffle furnace to the network?

Good afternoon, there is such a question, you need to connect a three-phase muffle furnace through the thermostat to the network, there is an approximate connection diagram (photo 4), but there is no connection of two relays that do not power the thermostat. I made it on the basis of a single-phase furnace connection diagram (photo 1,2,3) which works properly. Could you help with the connection?
