Air handler fan comes on after temperature setpoint has been reached

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?

any ideas.

Need pictures of the wiring at the thermostat and the wiring at the furnace/air handler in order to diagnose.
