My appoligies on this subject. I had two C4000, on gold trim and one gun metal. They had two different time delay times. I switched the gold face plate and knobs onto the gun metal one which had the shorter delay time and then sold the longer delay time unit, now gun metal one. I had in my mind it was a c4000t but now see there were two different offerings of the c4000. So the C4000t is quite different. I will stick to the c4000 over the c4000t. I currently have two gold face c4000 units. I plan to redo one this winter as per upgrades listed in this forum
No such thing as a C 4000t
C 4000 or a 4000t
