I recently bought Honeywell fan coil thermostat TB8575A1000 to replace my older Honeywell thermostat T8575D2003 which is discontinued by Honeywell.I don't know much about HVAC wiring. There are 8 wires coming out from the wall which was connected to my older thermostat
In this manner, By going through the manuals I figure out how to connected 7 wires out of 8 to the new thermostat
There is one more wire which is Violet in color and hooked to connection number 6 in the older thermostat T8575d2003 it's mentioned as Fan Common wire in T8575D2003 literature
I need someone to help me out by looking at the picture if the wiring is connected correctly and help me out where I can attach violet wire.
