I've heard mention of the remote display for the new controller. Do you know if this is a Ethernet type of unit or similar?
I knew eventually the final control would ship....I just tried a couple of hardware store cheapy countdown timers. Not the end of the world....but not as nice as fire, load, walk away until tomorrow.
This morning I was getting 105 degree water from the Garn inside, and the front thermowell said 140. I fired the 1500 up and burned for a good hour...final temp was 133! The stratification "problem", combinded with the load of making DHW (which was running on the 110 boiler supply), and dumping some heat into the floor. Though the house was a toasty 73....right on temp...though the mixing target was 110. But the boiler supply was 130 (compared to the 105). One of these days I'll have to look inside the tank to see the convection during a burn. Perhaps I should move some insulation around and tape some temp sensors up the side of the Garn. I wonder what the bottom temp was if the supply was down arount 105 and the front thermowell at 140. I burned I'm sure 60 pounds of wood at least in this one load, or some 300,000 BTUs. To get the fully mixed tank say up to 133, 800 gallons by 30 degrees is in the ballpark. That sounds about right, with a little load for DHW and heat and 8x% efficiency. Just funny to see those numbers. I was a good 18 hours since the end of the last burn....
pybyr said:For those for whom the main interest in the new controller is to do a post-burn shut-down, if you are electrically and mechanically inclined, you can use a thermocouple and a process controller, along with a relay to handle the Garn's large motor load. I recently installed a set up like that on my Econoburn, and it is working very well for this purpose-
This is the control I used:

Jim K in PA said:In addition to the separate relay, for a GARN you could also put the PID in parallel with the OEM timer for startup rather than ramp down the cut in temp on the PID. That is probably what I would do.
