7183288 and other probes

[Edgard]

Hello,

I have a Vitocal-350A and please find the serial number and details in the attached photos.

I have a Vitotronic 200.

Allow me to say that so far your team has been incredibly helpful and my project has advanced considerably.  

My installer has abandoned me after he just took my money and no longer wants to complete my project as he no longer sells Viessmann.

My question is about the house heating side.  There are 2 heat loops for floor heating and one loop for radiators.

My question is about the probes.

There is one probe 7183288 and can you let me know where this one fits in the overall design.

There are 2 smaller probes with red wire [please see the attached photo].

I have one ZK02941 which connects to the KM-bus and has its own probe which I connected to the output of the 3-way valve [HK3/KM].

So is there a probe at the output of each heat loop?

Again all your help is very much appreciated!

Hello @Edgard 

Regarding the connections and sensors, you can use this diagram.

The contact sensor with the red cable has the characteristic Pt500.

I still think that you should hire an electrician to help with the wiring.

Good morning and thanks.

I am an engineer so am able to do all wiring after which I will hire an electrician.

My issue so far is that the electricians/heating specialists who came to my place all say they need Viessmann to send a technician to start up and program the system.

I want to have the wiring as ready/complete as possible to make maximum use of his time.

Can you please confirm that for the A1 heating circuit, there is no probe to be installed at the output of the pump?  Only connect the pump to 2/212.2 connector on the Vitotronic 200.

I do not have any sensors in the house.  Only the outdoor sensor. So no 8/145.  

A1 has radiators with thermostatic valves installed.  So what will control the pump in such a case?

Hello @Edgard 

Heating branch A1 radiators do not need their own flow sensor, because the common flow sensor F13 is used for this circuit. The pump of the heating branch A1 radiators will only be controlled by the outside temperature and the time program. 8/145 is a KM bus distributor, which you do not need in your case.

Note:

For fine-wire cables, cable sleeves are usually used on the terminals.
