I’m working on getting my Wyze Thermostat setup but I ran into a snag. On the thermostat, I have Rc jumped to R, Y, W and G. So the instructions say I need to install the adapter at the control panel. However, when I look at the control panel, the C is in use and the instructions indicate it should be open. It appears the wire in C goes to a PVC pipe on the drain line. All that being said, the instructions do say if a terminal at the control is sharing a wire, it should be ok as long as you just replace the thermostat wires with the adapter so is this ok with C as well? Thanks.
