Installing a digital thermostat
I installed this one in my 1995 but my memory fails me as to where the red and white wires go.

Help needed.
Thanks

I just installed a similar heat only digital thermostat last week, came with specific instructions for two wire heat only systems, connect to W and RH. (White to W, Red to RH)  worked just fine.

I believe your C says optional with batteries, unless you’re adding a third (powered) wire, just connect up White to W and Red to R.

Thanks Dave.
As usual I was over-thinking this.
