Hello,
I am KNX beginner and currently get blocked by an issue with the Gira X1 Visualization to control my heating.
background:
I have following setup in my KNX system:
Gira X1
ABB VAA/S12.230.2.1 Valve Drive Actuator
MDT Glass Push Buttons IIBE-GT2TW.01
it's unfortune I found it out too late that ABB VAA/S12.230.2.1 does not have a integrated PI temperature controller, namely it only accepts a boolean to turn on/off the value, but does not accept setpoint temperature together with actual temperature and then controls the valve automatically for me(I expected like this when I bought them). So now the situation is: MDT BE-GT2TW.01 sends actual temperature, ABB VAA/S12.230.2.1 only accepts a result from a PI temperature controller, and in the whole setup there is no device to provide a PI temperature controller. This situation resulted in 2 possible solutions:
1.use the logic module Controller Heating/Cooling in Gira X1 logic editor
2. replace the ABB VAA/S12.230.2.1 with other heating actuator which has a integrated PI controller e.g. MDT AKH-0800.02.
I am currently trying the 1st solution and will only go with 2nd one if the 1st solution is not feasible. but I got stuck here.
Problem:
I have created 2 group addresses:
1/2/4 test set heating control => it contains only communication object: 5752: X1 Decimal Variable 2 - Write Value
1/2/5 test read heating control => it contains only communication object: 5753: X1 Decimal Variable 2 - Read Value
both 2 GA have been set Data Type 9.001 temperature °C.
in GPA I assigned these 2 group addresses in a data point which is also data type of 9.001 temperature °C, and assigned this data point in the visu device Heating and cooling as setpoint temperature data point. basically the idea is I just want to persist the setpoint temperature from user and then later do the calculation via the PI controller module in the logic editor.
but in mobile app the visu control Heating and cooling does not react when I try to set a temperature. It just does not response at all when I click on any temperature and +/- buttons are grayed out. The Diagnostics in ETS also has no telegram. The interesting thing is, when I manually write a value e.g. 21°C into GA 1/2/4 in ETS, then the control could display the setpoint temperature correctly. I also tried to use variable data points or device data points but also does not work, i guess I really lack knowledge in this area.
so could anyone who has more experience about Gira X1 could help me have a look what is the root cause? I really appreciate your help!
Kind regards,
Tony
