How to setup the Danfoss HC10 hydronic controller with Danfoss Link RS_Z

Bosse Sahl shared this thanks 4 months ago

Hi,

I'm trying to setup a Danfoss HC10 hydronic controller together with 6 Danfoss Link RS-Z and virtual thermostats, but the controller keeps getting into fault mode.

I get the following fault codes, ref. the Danfoss HC10 manual:

Main LED: Red flashing ... Error mode for one or more thermostats.

1-10 Output LEDs: Green flashing ... There is an error in the chain or an indication is required.

If I switch on/off the main power on the Danfoss HC10 it is all cleared and it is operating normally again, but after a while I get the same fault indications again.

Has anyone setup this controller together with virtual thermostats or knows how to do it based on similar systems?

I would say you are the 1st to try the Danfoss HC10 controller.

Would you be able to help me if I take some screenshots of the controller on how it is shown on the zipato box or supply you any more information?

Well. I can try.

In my setup the virtual thermostat had the temperatur input from the Link RS-Z and the output to the corresponding output/endpoint (Ep) of the controller. Then when I adjusted the setpoint on the virtual thermostat the Ep-setpoint followed, but there was no connection to the Ep-thermostat mode on the controller. I solved this with a rule, but I guess that is not the correct way to do it. How do I connect this heating setpoint to the thermostat mode. There must be a way to associate these parameters together.

It looks like the controller is checking on some parameters as it will run for a period of time and then stop with the fault codes given by the LED lights, error on thermostat and indication required.


Here is a link to the manual: http://manuals-backend.z-wave.info/make.php?lang=en&sku=DANEHC10

I have also attached some pictures of how the controller is displayed in my setup.

If you need any further information or settings I will take more screenshots.

Do I need to make rules for this to work or should it be enough to make the correct associations, and the correct use/setup of the virtual thermostat. I use a rule to update the setpoint from the virtual thermostat to the Link RS-Z thermostat and the opposite way, so that the set points always are the same. Can this make any problem here, and can it be solved in another way?

Can you show me the virtual thermostat endpoints settings?

See my image below. I guess you need to set the following:

Heating input - Danfoss RS-Z

Temperature meter - Danfoss RS-Z

Heating output - Danfoss HC10 - the same corresponding heating output circuit as the danfoss RS-Z is located.

This is the 1st step. I need to read the manual to understand more about the error codes.

Also, can you please sned me the possible configuration parameters you have for HC10? If you open the device manager and open the setting for the root level device, you should have a tab called configurations.

Originally I did not have any device on the heating input, but I have now adjusted all virtual thermostat like the one on the attached screenshot. Also attached is the configuration tab.

Ok. So it seems that no configuration parameters are loaded when including the device to Zipato.

Nevertheless, you have in all virtual thermostats set up inputs - so this will allow you to manually change temperature.

Looking into the errors you mentioned at the beginning of the post it seems, that the danfoss shows an error with a specific output. Can you tell me which output is flashing green? This indicates that that specific output has problems.

All the outputs are flashing green after a while, so the controller is checking all the outputs and gets the same feedback or is missing a feedback wich gives a fault indication.

Hmm. Interesting. So it seems that the outputs are not recognized? The manual for Danfoss states that all should be setup before connecting the HC10 to power and inlcuding. perhaps this is due to the fact, that the HC10 does a self check to test which outputs are connected at all.

I guess it is a stupis question, but still. You have all outputs connected to the appropriate valve? 12-24V? Did you connect the valves after or before connecting power to the HC10?

I included the controller before connecting the valves, just to check the controller. All valves was connected before it was setup, but after it was included. I have connected 7 valves to the controller, and all are 24V.

Should I remove it from the system and included it again now as the valves are connected?


What about the connection between the ep-thermostat and the ep-mode on the controller, do you think this will be linked up when the controller is included with the valves connected?

I will not be able to do this the next two weeks as I am away on work, but I can give it a try when I am back home.

Do you have any other solutions to try before I do this?

When I said all outputs give a green flash after a while, it is only the outputs wich have valves connected that gives this fault code. The ones that are not connected is in off position and does not give any feedback.

Well, so evidently the Danfoss recognize the connected valves. I would advise to contact Danfoss for more info. Sotty Im in no further help.

You can always raise a support ticket with Zipato as well.
