We just bought the whole setup including the Danfoss valve from you last month...the valve is working correctly as far as we can tell (it's engaging and opening).
The issue I see is that the Danfoss is useless if the condenser is not cooling distillate. If we can't get output without flooding the top plate, there is no distillate to cool and condense so the valve operation is mute.
Am a pot still guy, not a column guy. I'm sure we're missing something but it's just not apparent to us.
