    York XL Trouble Output to York IAQ Thermostat

    Is there any method to connect a York Heat Pump's X/L output (trouble status) to a Honeywell Vision Pro IAQ thermostat so that the user can see the trouble flashes? My 20 year old Lennox thermostat could do this, but the York service folks say the IAQ has no capability in this regard.

    How many times must one fix something before it is fixed?
