PB 105 #2 Dip Switch

All my dip switches are in the off position. My dealer told me that switch # 2 is for the quanity of pellets in the burning pot prior to firing on start up. I tried mine with the switch # 2 in the on position, not enough pellets for ignition.

Wil,

Does turning it on increase or decrease the amount of pellets during start up?

Thanks,

Andy,
I found with dip switch in the on position, it decreased the amount of pellets in the burning pot on start up.

I'll check mine tonight and see. The installer definitely mentioned something about the setting of #2. It is different from the rest of mine. Does anyone know what the rest are for? I'll post how mine are setup later when i get home.

The first 2 dips are in the up position (on i assume) and the second 2 are in the down position.

Yea, I can see 4. It really depends on how that little metal punch out tab is punched. I can't see far enough in to see how many dip switches there are total, but I know there is more than 4. Any idea on what that #1 switch does? They should really list all this chit in the owners manual instead of being all secret service about it.

Does anyone know what they are all for?

Andrew,
Do you have pics of how yours is plumbed in with your existing boiler? I don't understand how my OB could possibly be getting heated by my PB...

Just got off the phone with my Harman dealer. He says the first 2 dips are for amount of pellets for ignition and feed speed during ignition. Also agreed that this is by far the worst owners manual he's ever seen. lol

Both of mine are on. He said they both had to do with the number of pellets on ignition as well as the time the feed is increased for ignition. he didn't specify what was what. He flat out told me that Harman was specific and said that dip switch position was dealer info only and they didn't want customers to be messing with them. My dealers pretty cool though, so he told me without any probs. He also said he didn't know what the other dips were for as the boards are used in other machines also.

Nice friggen setup! What is the blue and white boxes as well as the box connected to the pressure relief?

You're the friggen man. I'm gonna show my installer your pics if you don't mind. I'm getting an aquastat on my pressure relief as well as a circ inbetween the two boilers to i can heat the oiler with the PB. Thanks!

Andrew, mine came from factory with all visible dips off.

I just had mine installed by the same guys who installed Wayne's....with some of the same problems (right Wayne )
Strangely enough, all 3 of my "visible" switches are down and the 4th & 5th (can see behind the panel) are down and up respectively.

Would this cause A LOT of smoke at start up if these aren't set right ?? I mean, A LOT...enough where my neighbor's have come over thinking the house was on fire. Same with my wife when she has pulled into the driveway as it's starting up. And 2 of my employees thought the same thing while at the house loading up equipment and materials for a job they were heading to. One even went into the house to make sure all was ok...........

Hey Andrew, Have you had any exp with the psu for you circulator pumps pooching ? I started off with an Argo that powered my pumps. Both relays died and now I have a Taco. Seems like the same thing has happened. Any thoughts here ? Also all my dips were shipped in the down position.

Hey Andrew, PSU ,Power supply unit sending 56 volts AC to the pumps. Pooching means failing. Thanks for the info. I'll try to post some pics as soon as I figure out how to scale them.
