Installed a Wyze thermostat to my TRANE system, (though the outside unit states it’s a heat pump - as per the HVAC contractor it’s setup as conventional system) Connections looks such, During the install test - Heat (gas) works fine, as Y1 and Y2 are connected - Cooling for Stage 1 works fine,(outside condenser fan kicks on) cool air flows, When Cooling test for Stage 2 starts, the outside unit condenser fan turns off, but the unit (upstairs) still pushing cool air. Does not seem normal, Is this just a bug or a limitation of Wyze 2 stage cooling test? Not sure if there is any other way to test this - if I adjust the thermostat to start cooling - how would I know if stage 2 cooling has kicked in? App Adv settings: Coast to Cool is off, Fan Act Delay by Furnace, Fan Cycle: Off
You probably have a time delay/ energy saver on your cooling which turns on for a few minutes when the stage 1 compressor turns off.
