Eurotronic Spirit Z-wave thermostat- Valve opening percentage report

[CoopR 2]

 

Hello everyone,

 

As many before on this forum I'm working on my heating system and want to convert my current single room heating plan into to a multi zone heating plan.

I want to integrate my boiler into my heating plan but want to create some safety interlock that I won't fire up the boiler if all the thermostats are closed.

 

I think this is a very important feature and often overlooked as the behavior of a thermostat is to close more and more when the thermostat is reaching it's set-point to prevent overshoot.

 

So therefore I need to know what to position is of the valve, based on that condition i went for the TRV's of eurotronic as it stated in the manual that it is able to report it's current valve position.

And it looked like everything would work correct with the fibaro template as I was able to set parameter 6 and enable the valve postion reporting.

 

I think everything is configured correctly but i have a bit of strange behavior now in fibaro when I enable parameter 6.

 

The setpoint value is getting overwritten with the valve position percentage:

 

Setpoint displays: new setpoint in degree Celsius

After few minutes same device is overwritten and setpoint value displays Open valve percentage (unit doesn't update and stays on degree Celsius):

Enabled parameter 6.

 

 

 

When i change setpoint and debug the info.

I noticed the following behavior:

 

Setpoint change -> Setpoint value displays setpoint -> after few minutes Setpoint value displays: valve position -> Setpoint value displays setpoint value again.

 

 

Maybe I'm looking at the wrong values but here is the list of the available values:

I wasn't able to locate the opening valve percentage value in this list to make a virtual device as work around..

 

 

Does someone have a solution for my problem?

I would like to receive the actual setpoint and the open valve percentage on a different value/device.

Yes, I can confirm this is working as Jeroen_ had explained it. I am doing it since last year with some minor changes:

When turning on the Thermostat, I am using following sample logic:

         fibaro:debug("*** Turning on Heating in Room")
         fibaro:call(Heating ID, "setMode", "1")   -- set the Heating to ON
         fibaro:call(Heating ID, "setMode", "15") -- set the Heating to MAX - use this to open the valve directly
         fibaro:call(Thermostat ID, "setThermostatSetpoint", "1", "28")  -- set the Thermostat to 28°C 

 

When it has to be turned off I use:

         fibaro:debug("*** Turning off Heating in Room")
         fibaro:call(Heating ID, "setMode", "0") -- set the Heating to OFF - will closed th valve
         fibaro:call(Thermostat ID, "setThermostatSetpoint", "1", room.roomSetpoint)  -- I am using another logic to set the Thermostat back to the value maintained in the Heating Panel

 

When you install the Thermostat you will get the below two functions, beside the Temperature
