    C8822901-E293-4E2D-BE08-3D0305DF55A9.png i got the furnace running the other day by bypassing the thermostat. It was missing pieces. I was told to replace it with another low voltage thermostat. I was going to buy another hoenywell but I scored one a little cheaper on Amazon. Hope I didn’t scare myself though.
    The Honeywell was wired with the red wire to the R terminal and the white wire to the W terminal.
    The new one however does not have an R terminal. So I guess my questions are 1) is this thermostat compatible? And or 2) does the red hook up to a different terminal. Here are the terminals provided. 7C957F09-04B1-4941-8428-804B93A17543.png

    My electrical is almost as good as my plumbing expertise (Sh** rolls down hill and payday is Tuesday) BUT my uneducated guess would be the R(H) terminal, think that's "hot"...I'd check mine but can't pop it up at the moment.

    connect your Red to Rh and your White to W and all will be fine

    Update. All worked good! Red to (Rh) that was the money maker! $14.00 on Amazon... pictured with Honeywell. E937A079-1C29-4C3F-A2D0-4EF359F89A76.jpeg E65FA9FE-2D0F-48B1-A9A9-AB14B999A28F.jpeg
