Honeywell YTH6320R1023

Tested the thermostat and that doesn鈥檛 work. Could be the corrosion on the tabs for the battery鈥檚 or could be more. That鈥檚 why I鈥檓 selling this for parts. Have not tested the module because I have no way too. Doesn鈥檛 seemed to have anything wrong with it so there is a chance this works. That鈥檚 why this is for parts.
