the t wire is for an outdoor anticipator reset. If you dont have a terminal on your thermostat it does not have to be used. Just tape it off.

Just mark the old wires on the old thermnostat...R , W etc...and put them on the same terminals on the new 1.....also there should be some adjustment ire : switch on the back or under the cover to adjust for Hot water heating or electric heat...either is the setting you should have it on....also you shouldn't setback the thermostat at night or when away very much....2 degrees is fine , as the boiler will run along time to raise the temperature in the morning and may not get there by the set time

The Rc and Rh should have a jumper wire between them let it in. and hook the red wire to one of them it does not matter which one as they are jumpered. The white wire goes on the "w" terminal and the Blue wire will go on the "G" green terminal to run your fan.
This should get you up and running again!

Leave the factory jumper between R & RC. Connect the wires to the new stat just as you have them labeled. Use a piece of thermostat wire to make a jumper from AUX to E terminals. Your new thermostat should give you instructions on how to access the installer set up. You are going to set it up as heat pump with aux. I see this is 2 days old but if you need any help let me know.
