PB 105 #2 Dip Switch

[AndrewChurchill]

I was perusing another pellet forum and one of the posters recommended putting the #2 dip switch into the On position. He said Harman told his dealer to turn this switch on.

All of the other posts I've read on this forum and the iburncorn forums have said to leave all three of the visible dip switches in the off position.

My questions are what does the #2 dip switch control and is anyone else who is using a PB105 have their #2 dip switch turned on?

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

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.

 

[Wayne64SS]

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

 

[AndrewChurchill]

Wayne, that means that you have 4 dip switches visible? On mine I can only see three and all of mine are in the off position.

Wil,

Thanks for the info. Based on your response I will not be turning that switch on since occasionally too few pellets are put into the burnpot at start up and that causes a failure to ignite.

 

[Wayne64SS]

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.

 

[AndrewChurchill]

There are a total of 10 dip switches.

 

[Wayne64SS]

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...

 

[Wayne64SS]

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

 

[AndrewChurchill]

Wayne,

I don't have pics of my boiler yet but I will take some soon.

I understand that the #2 dip switch reduces the amount of pellets during ignition. Did your dealer tell you what the #1 dip switch does or what happens if you turn them both on?

Thanks,
Andy

 

[Wayne64SS]

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.

Wayne,

Here are some pics of my set up.

 

[Wayne64SS]

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

 

[AndrewChurchill]

Wayne,

The box connected to the relief valve is an aquastat. If it measures that the water temp is less than 100F it sends a signal to my oil boiler and tells it to turn on.

The blue box is a low water cut off. If it senses that there's not enough water in the pellet boiler it turns it off.

The white box is a timer. I use it to automatically turn the boiler on and off during the summer so it's only on when my hot water tank is calling for heat. Right now the timer is acting simply as an on/off switch since I am using the boiler 24/7.

 

[Wayne64SS]

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!

 

[AndrewChurchill]

Wayne,

Glad I could help. If you need close ups of anything let me know.

BTW, my PB does NOT heat the oil boiler. I am using a parallel set up, which is the more efficient way to connect two boilers together and that's why I need two circulators instead of one.

 

[nmerrill]

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

 

[AndrewChurchill]

Mine did too but now it appears that Harman is telling some people to turn one or two of them on.

 

[taperk600]

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...........

 

[AndrewChurchill]

Tape,

All my switches are in the off position as well. I've found out that the #2 dip switch in the On position will feed pellets for 2 minutes and 41 seconds and in the Off position the auger will run for 3 minutes and 24 seconds.

Both my PB and Breckwell Big E smoke on start up I don't think this is out of the norn. My PB does smoke longer but I suspect this is due to it having more pellets in the burnpot as compared to the Big E.

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.

 

[AndrewChurchill]

Stephen,

I'm not certain what the PSU is or what pooching means, but so far all of my equipment is working as it's supposed to. There are some pics of my setup on page 1 of this post. This may give you a better idea of what I'm using for equipment.

Andy

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.
