That works great! Thanks for all your help. I still have one problem. My old graphite fitting for the roto-damper won't fit this. When my fire temp gets above 500F, the temp of the metal mounting tube gets up to ~300F and the rectangular to circular adapter softens and sags due to the weight...

OK. I just checked that I only need the 2 wire fan: "If you have a third blue wire on your fan (RPM sense) just cut it off as HeaterMeter does not provide RPM monitoring. A little heatshrink tubing makes a really nice connection." The F00 designation is for the tachometer wire. Delta does not...

Hmm. I forgot to order the 15cfm fan. Does anyone know what model is needed and where I might find one?

Thanks Bryan, i should be able to find the servo and I appreciate your supplying the ethernet jack. How can I make the arrangements? My direct email is webdove@gmail.com. Thanks, Web

1 3/8 ~= 35mm. That should work perfectly. Is anyone willing to sell me the parts for the 15cfm version of the adapt-a-damper with that round adapter?

My current rotodamper looks like this. It has a 1.25” conduit tube on the plate and a graphite round to rectangular adapter for low heat transfer. For the 15cm version of the adapt-a-damper it appears that I will need a 1” round conduit fitting with extra fiberglass tape since the guru adapter...

Do you happen to know that diameter?

Mine is 33.8 x 26.3. Much smaller. Does the large adapt-a-damper have a rectangular to round adapter? Mine ends in a 35.8 mm round opening.

Hi, Is anyone willing to sell me the components for a 15cfm adapt-a-damper? I have an early Beta roto-damper that I love, but the extra fan output would be helpful. Also I need to know if it has the exact same outside rectangle measurements as the roto-damper. I have a custom made graphite...

I downloaded a fresh copy without the customization of wifi and it seems better now.

This is my configuration page. I had downloaded the “pre-configured” image. I am trying the “non-preconfigured next”. The images are here. https://www.dropbox.com/sh/sg6fyytqhrel3r8/AADU7-oKtzCgKTxSeXVthgbna?dl=0

Any idea why the latest version with my version 4.2 is ignoring lid openings. I have it set to 2%.

I think I have the tool to pull the pins on the existing female socket, so I will probably re-solder the new leads to them given that I only need the one. Hopefully I can look for low impedance between the black fan lead and the black servo lead since I unplugged the servo without paying...

Mine has a white female 2 pin PCB connector. Interestingly, when I looked more carefully it appears that the fan blades actually melted due to heat exposure.

Hi Ralph, My RD3 blower died. Fortunately I had the high flow RD to use temporarily. I found a 108-BFB0512VHD at mouser, but I forgot that the female PCB connector must have come with your parts. Do you recall that part number or identity? I don't have any part info in my notes and I...

Hi Ralph! I remain the happy owner of one of the early beta RD3s. We talked briefly in 2015 about changing from the 50mm to the 70mm fan for more power. In the end I decided to keep to the 50mm for good low temperature control. For high temperatures I simply open the screen part-way to provide...

You were exactly correct. The linkmeter had forgotten most of its settings. Fortunately I had some old emails and onenotes with the settings and was able to recover. Thanks very much Bryan!

Hiho, Yesterday when I started my 5 year old HMv4.2 it reported a pit temp of 670 when the fire was cold (32ish in New Hampshire). Today I pulled the board to experiment. 3.3v power is good. Food probe 3 is at 2.5v when connected to a minijack probe at 69 degrees F. The HM reports that probe...

I found an elegant solution to this problem some years ago. A machinist friend made a blower to grill tube adapter in the same configuration as the one that came with my RD3, but made it from a graphite rod. It has very low thermal conductivity and does not oxidize until something like 1200F...

Ah. Thank you. I suppose that I could raise the pulse duty cycle on the bottom and that would keep the vent a little bit open.
