Installing a digital thermostat November 30, 2022, 02:22:40 pm I installed this one in my 1995 but my memory fails me as to where the red and white wires go. Help needed. Thanks
Re: Installing a digital thermostat Reply #1 – November 30, 2022, 04:03:02 pm 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 youâre adding a third (powered) wire, just connect up White to W and Red to R. edited by RonB to add a link: Emerson 1E78-140 Non-Programmable Heat Only Thermostat for Single-Stage Systems 2 Likes As an Amazon Associate Lazy Daze Owners' Group earns from qualifying purchases.
