thermostat cycles properly but air handler fan stays on. after looking at the circuit it appears the emergency heat relay is on but you are not giving it a signal on the * terminal.
the relay in my air handler is unusual since it has a resistor symbol for the coil of the emergency heat relay. My old thermostat for the heat pump systemis very old and has mercury sw in it.
Was working when I switched over to the wyze thermostat.
i’m using O/B, W1, G, Rc, C, Y1, *
Seems to function perfectly if I could figure out why the emergency heat relay is on with no control signal?? very strange to me?
