Hello,

Does anyone manage Johnson Controls ventilation unit via Bacnet? Does it work good or bad?

Our customer wants to manage Johnson Controls huge ventilation station in offices and ventilation controllers are Johnson Controls IOM and Johnson Controls FEC. As I understood, we have to connect IOM controllers via cat6 cable and connect it via bacnet in bos configurator, then I have to find which addresses has managing functions.

Maybe I have to connect it other way?

Will be thankful for any advise.

Regards,

Artjom

What do you use to control floor heating? I bought a

R4DCB08 8-channel RS485 DS18B20 Sensor Board MODBUS RTU, but the temperature value every now and then drop down to 0°C and I don´t know why. And for the valves DANFOSS ‑ Z‑Wave Hydronic Controller HC5, didn´t get that one to work either. So I am looking för a better solusion.

I have 2 variables Double (setpoints) A and B. When I change the value in one I want the following rule. A can´t be smaller than B and B can´t be bigger than A . Any ideas?

Hi, I have already seen in the description that it works for the F454 but, please, could you confirm whether or not it is compatible with the Bticino F453 server? I have a client with this model, I have made several tests and there is no way it works and I don't know if I am doing something wrong or if it is simply not compatible.

Thanks for your help. Regards

Pablo

Dear

I am working on an energy measurement project for a customer, in which I intend to implement Comfortclick/bOS as the management system.

I have established a modbus connection between an energy measurement device from Finder and the bOS. I simultaneously noticed that the measurement (voltage, current and power) shown on the Finder display differs from the reading obtained by the bOS which is slightly higher.

Settings:

Connection Type: Serial

Serial Transmission Mode: RTU

Low Word First: False

Low Byte First: False

Data Format: LittleEndian

Write Function Type: WriteSingle

Read Function Type: ReadSingle

Modbus Table: InputRegisters

Data Format: Signed32Bit (to power) and Unsigned32Bit (to voltage and current)

Scale Factor: 1

Use Status Address: False

Readcyclically: True

Please, could you help me with the configuration in order to get the correct reading?

Thanks,

Eduardo

we are facing in the last week a problem for new customers with IOS to connect to the client. we have the latest version 4.9.17.

it tries to connect for few seconds and come back to the server lists.

we tried also with the manual configuration, still same behavior.

Hello. I have a problem opening the Client application on my pc.

After making a version update, when opening the comfortclick of a certain client, I get an error that I suppose will be a matter of changing https for http or vice versa.

The problem is that I cannot correct the error since the Client application always opens by default on the last server visited and does not give me the option to modify the connection data.

Is there any way to prevent the client application from directly opening a server and displaying the list of devices. I have tried reinstalling but it is not the solution.

Thank you

Any suggestion ?

Hi,

Its it possibe to read group value from bOS server. :E.g: "GroupValueRead" sent from KNX network and then get response "GroupValueResponse" from bOS?

I tried to change "Read" flag to "TRUE" under Commuunication section but bOS is still not responding to "GroupValueRead"
