I’ve noticed that wyze will not run my high efficiency dual stage gas furnace in the second stage. With dual stage gas furnaces, in order to fire in the second stage, both w1 and w2 need to be operated at the same time. Is there a way to tell the wyze thermostat to do this?
My wires are correct, checked at both the furnace and the wyze.
(My furnace has an ECM and takes care of the fan speeds, whereas if I let the wyze control them by hooking up the green wire, it only runs in low. This is disappointing, as I usually run the fan by itself in the summer to circulate cold air from the basement and cool the house.)
And yes, I did set the dip switch on the furnace board to allow the second stage to be controlled by the thermostat.
When I do the test, the furnace runs properly in first stage (W1), but not at all in second stage (W2).
