Hi all. I am attempting to replace a manual W-R thermostat model 1F58-72 with a programmable W-R model 1F82-261. I think I have all the wiring doped out except for one. The 1F58 has a blue wire on terminal X1. I don't find a comparable terminal on the 1F82. This wire seems to go the stage 1 heat and cool anticipator. I don't see anything on the 1F82 diagram indicating an anticipator. The only thing left on the 1F82 is a connection at terminal C which is common. Any suggestions are appreciated.
