Hi, the compatibility checker has me a little confused.
If I select R along with W and C then my system is not compatible but if I select RC (bridged with R) then it becomes compatible.
I’ve also noticed the lack of option for K which according to the knowledgebase below is specific to Honeywell thermostats without C wire.
Expert guidance appreciated

Welcome to the Wyze community @thangng3!
I’m not an expert but @Chuan is! I’ll see if he has the answer.
The jumper between RC and R is if you have one transformer powering the system. If there was two transformers, there would be a wire to RC, and another to R. The typical setup is one transformer (inside the furnace/air handler).
Honeywell wire saver modules combine the Y and G wires to form a single K wire that connects to the K terminal on some Honeywell thermostats. It’s used for systems that don’t provide a C wire but have a thermostat that requires one. You may have one inside your furnace/air handler which looks like the example below.
Thanks Brian and sorry for the late reply.
I’m not sure what to make of my setup since I have a C wire currently in use.
I’m thinking of getting a Honeywell 9585 smart device instead now for better compatibility.
