Can it be completed without DHW at all? Mine gives me error code f7 no DHW connected constantly and it’s annoying. I have it for heat only as I have a heat pump water heater.

Interesting presentation ,thanks for posting.

Where do I have to connect wires

Great instructive video. Thx

It doesnt get last the wifi pairing. My phone connects but the app cant see it

How do you turn heating on or off via app?

How do I turn heating up or down via app ?

How do you turn on or off heating via app? Or how do you control heating via app? If I want turn heating up or down?

I can’t believe we call b2hb as our legacy product now. 😢

I keep getting E12 code. Anybody with a definite solution?

What does the solid red LED status mean? How to solve this situation?

thank you for the great combustion test video jason

Hi there, I am working on a Vitogate 300 and when I want to add the points on the database for the BMS System it takes too much time to discover the points, or it times out and does not discover the points at all. Any explanation?

The Audio is so bad on this video that I transcribed it so it is easier to understand. The audio starts around 30 seconds and ends at about 1 min 30 sec. Hi, my name is Moises Delgado, and I'm with Veissmann Manufacturing. Today, we'll be discussing a few issues you might encounter in your Veissmann boiler. In this example, we're going to use a zero D (0D) fault. Oftentimes, you may encounter your boiler in an idle state, and you decide to press the reset button, and all of a sudden you'll get a fault that says zero D (0D). A zero D fault just means that the reset button was pressed out of sequence. It's really more of a nuisance fault, but I'll show you how to clear it today. The first thing we're going to do is we're going to open the trap door area. We're going to select the fault search with A. This time it will display the fault, zero D (0D). I will acknowledge the fault zero D as well. Then close the trap door, and press the reset once. (He presses and holds the reset button for about 1 second before releasing) Within a few minutes, the boiler should fire up again, and you have a green light indicating the flame.

Excellent

How come tech support for viessman can’t tell me what the voltage is that goes from the board to gas valve . Vitomens 100-w

Great video!

I have a Viessman 100 combi installed 1 year ago. It works fine from the ViCare app but won't accept being controlled by a third party wireless room thermostat ( HONEYWELL T3R) . Can't figure how to switch it on at the boiler either so left frustrated by it all. Original company that fitted it left scratching their heads.

When I search ViCare in the App Store, it doesn't find anything useful.

What’s the price range?

Great, there is a chance to find this using celsius scale for temperatures? Thanks

Wife password has been changed, Not connected wifi. I want to connect again, how can I do?

What is f8 please on this boiler?

can this be used as an AHU for a Carrier Aquasnap Chiller?

I have recharged my connection along with other 2 connections one sor my wife and other for my sonfor Rs. 99 each. Our connection using for several years. Now your message came that I will not receive any email message. If not recharged for higher amount If so I will stop and cancell my 3 cellphone connection shortly

You have confused current and voltage! You state to set meter to AC current then you are using it to measure AC voltage 🤷‍♂️🤦‍♂️ That is a fundamental error that could cause damage to things since if meter was set to current it will short circuit the item you probe across.

We had the house power cut off from hydro and when they powered house back on an hour later we tried starting the unit/ boiler and it started the info screen for about 2 seconds and then it tripped the breaker we tried to start again a bunch of times but just keeps tripping the breaker can u tell me what it could be and how to fix.pls n thx.

I just installed an outside temp sensor but my B1KA doesn't have an option 15 on menu 12. It cycles from option 14 back to 0. Is this a firmware issue or is there another option that precludes option 15 from showing?

When you flush the debris with water towards the end where does the water and debris go? This part is not clear to me.

Can you please advise why the one bar flame symbol is constantly shown on my boiler. I think my boiler hasnt switched off for over two months. It is constantly running on one bar flame symbol. Even after resetting it per your video instructions.

Hello, what is the correct range for the vent pressure?

Finally 😀. Looking great.

I’m curious when there is a call for heat from a thermostat does the cir pump come on or is that timed?

Why does the DHW show 2 dashes? I thought it would show the temp of the water like it does for the baseboard heat.

Look at you, Viessmann US! Finally done. It is beautiful. Congrats! 🎉

Why new flow switch died in 1 month? Had a spare thankfully

I am currently have B1HE-85 to replace a WB1B model , the existing cpvc is 2" but the B1HE only comes with 3" flue connection , is there a 2" flue connection for B1HE-85 ? what is the part number of it ? thank you .

What happens if the sticker is not present on the boiler. Where do i find the 3 pcs of info required to fill the app questions manually

I have the 0b fault code occasionally. It happens mostly in the morning when the central heating needs to heat the place several degrees. Seems like switching to hot water is a trigger. Sometimes switching to hot water and back to central heating causes the 0b to show. Other times the fault code 0b is already there and switching to hot water makes it go away. When 0b shows, at all times hot water is available when i open a hot water tap. At all times the pump keeps running. It's just that on central heating the burner will not activate. Sometimes before the 0b shows i can hear the burner try to activate but fails, or the burner runs for 2 sec and stops, then 0b shows. A few times i saw when temperature drops below 50c the burner succeeds to activate and 0b is gone. Could you possibly give me some insights before i start troubleshooting?

Do you need a room thermostat as well or does the vi controller act as a thermostat?

Is there a new part number for the up dated check valve? What are the symptoms of needing it?

Same. I get the e12 error

I'm actually looking to install the 4-pipe system

Guys great vid can anyone find the equivalent for the U.K??? I'm obviously a u.k plumber and I can't find anything :-(

We’re having difficulty connecting our new system. We are unable to pair to the boiler from the app. Any suggestion?

How change contry?

Awesome! Looking forward to new larger sizes to appear soon.

Hi there. Thanks for sharing this valuable information. Do i need an extra pump for the indirect DHW tank? i am planning to install the B1HE 120 with a 80 gallon indirect tank. I see the boiler has an internal pump already. Do i need to install an additional pump on the Tank heating supply side? or i just connect them directly? The distance between the indirect tank and the boiler is less 4 feet. Thanks
