Help with new thermostat
Planning on buying a new digital thermostat this afternoon but wanted to ensure a new model would be capable of being installed with the current wiring. Most likely going to get a Honeywell RTH2300B1012 unless there are recommendations otherwise. The current set-up has two red wires running to the R terminal, a separate red wire running to YY2, a blue wire running to G, and a white wire running to WW1. Any guidance is appreciated for how these would be mapped in a more modern thermostat.

The new stat that you want will work.
Wire it the same as the existing thermostat.
Connect the 2 wires on R to either R on the new stat and keep the jumper between RH and RC found on the new stat installed.
Do you have electric heat or gas heat?

Electric heating and cooling. Stupid question, what's the jumper? And I'm assuming there will be spaces for RC and RH on the new thermo. Thank you very much for your help!

Two red wires running to R ----- R and leave the R/Rc jumper in place that comes with the stat.
Red wire running to YY2v------- Y
Blue wire running to G ---------- G
White wire running to WW ----- W
Move jumper JP1 on back of stat to HE location.
