Thermostate - red wire

I only have one red wire coming from my system (new construction). Wyze says hook it up to RC (I do not have a jumper or anything in my old thermostat for RH.)

Anyone see this before? Am I good with just using RC? I thought RC was cooling (which works just dandy) but heating (RH) seems to be slower or just forced air (hard to tell here, it’s warm already.)


Wyze powers itself from Rc. It internally jumpers Rc to Rh for output to the air handler/furnace if you do not have a Rh wire.
