Hi!. First The Code is not F68 it is Fb8, and related to internal circuit fault. What Honeywell recommend: 1.Ensure that critical load terminals (5,6,7,18) are NOT externally powered or shorted. Reinstall or replace the Program module and reset controller. Reset controller, if Fb8 reappears, replace controller. There is long list internal fault signals. Good luck
