My AC contractor installed two Honeywell TH6000 thermosats

Customer Question

My AC contractor installed two Honeywell TH6000 thermosats one to independently control temp down stairs and the other to independently control temp upstairs. There is an actuator in the main duct that closes or opens based on the commands of the thermostats. My issue is one works fine for both heat and colling the other only blows out heat no matter of the setting. My contractor has been out 6 times and says he has fixed it but it never seems to work properly. just looking for some guidance.
JA: Did you double-check the thermostat's settings? And what about the filters?
Customer: I check the settings and filters are new
JA: Do you plan on doing the work yourself?
Customer: no I just want to give my contractor some new ideas
JA: Anything else we should know to help you best?
Customer: no
