For those of you with recently produced AHS Coal Guns with Thermal Ash Control, and who have a reasonable understanding of how they are wired, please critique my attached PDF file, which is my proposed (highly tentative) schematic for adding a Tork EJWT Percentage Timer (sort of like an RC, or Repeat Cycle timer, but based on user selected percentages of multiple selectable time cycles) by which to occasionally fire up the fan and "fan the flames" a bit, mainly to get some periodic heat into the chimney and raise my summer draft a bit.
Darren, we haven't called upon you since you joined up. Are you still lurking? If so, please have a look at this PDF and let me know what you think.
I propose to fire the fan for 3% of every 60 minute period. That would be 1.8 minutes of firing per hour. The orange wire normally goes right from the low water cut-off (LWCO) and into the L4006A, but I plan to route it to power the Tork Timer instead. Not shown here, but downstream of the R1 Relay on the AHS schematic which I'm looking at lies the L4081B high limit aquastat switch and then the fan motor.
The six blue terminals seen in the schematic are the wire terminals found inside the Tork EJWT Percentage Timer. It has both NO and NC switches. The L4006A is a NC aquastat that opens on temperature rise to break the circuit and shut off the fan motor. My main concern is that in my schematic the L4006A is to be bypassed for 1.8 minutes out of every 60 minutes. Would this be a show stopper?
