What is TFI (the flame initiation)??? If I have a two wire thermostat do I still have to add a third wire running from the "C " or common port on the thermostat i'm connecting on one of the L one (neutral) circuits? I know power can go into eight thermostat and then come back out of it on a two wire system. But with a three wire system my thermostat would get power. I measured my Carlin and it puts out 18 V
I have this exact model and ot keeps going into lock out I reset it and then works great for one heat cycle with a blinking greelight any ideas on what it is ?
It has a blinking green light because it's running and it sees flame. when that flame dies then it goes into lock out and you see the red light. That could be because a CAD cell goes bad and does not see the flame. Or Your igniters are bad and not initiating a flame. Or after your igniters initiated a flame that flame became extinguished due to something like a clogged nozzle or some other issue. In which case there would be no flame and the cad will then cause a lockout.
