Do your thermostats operate MANUALLY? Review your settings for both thermostats. To operate on auto you have to lower temp settings for AC, below ambient temp, and raise temp setting for heat. This may take a few minutes to activate heat/cool

If neither of these actions turn the heater or air conditioner on, remove the cover to verify the small colored wires are connected properly inside the unit as per the color-coded wiring diagram in the user manual. If the wiring is fine, the problem could be a problem with the heater or air conditioner, or you may have to replace the thermostat because of its age.
I recommend a qualified technician to check your system and replace/upgrade to digital 6 wire stats if needed.
