Programming of water underfloor heating

[fkaasin]

Hi

My ground source heat pump with water underfloor heating system is currently being installed and I need to program it. I was planning to let my supplier help me out, but I'm also quite interested in learning this my self. I have installed Gira Pushbutton Sensor 3 Plus 2 in every room and to control the valves I am using the Gira heating actuator, 6-gang with controller.

So I was wondering if there were anyone here familiar with this setup and that would share/explain a basic programming scheme for it. My biggest uncertainties are what connections must be setup and connected in ETS.

I just need to setup the valve control and pushbuttons. No need for stopping/starting circulation pumps etc.
Any help is greatly appreciated

Best regards

For efficient operation of a heat pump, it is crucially important that you have the system running with the lowest possible flow temperature. How is that ensured in your installation? Is there any way how KNX can tell the heat pump how much heat really is needed?

Having the heat pump run with too high a flow temperature, and then simply reducing the flow with RTCs and heating actuators per room can result in very inefficient operation. The heat pump should reduce its flow temperature to the point where at least one of the valves controled by KNX is fully open (of course without overheating the room). Ideally you would have the flow through each room's underfloor circuit adjusted such that, under normal circumstances, all valves can stay open, and only the flow temperature coming from the heat pump needs to be controlled (by all room temperatures together).

Ich persönlich stand auch schon vor diesem Problem, konnte aber kein gutes Schulungsvideo oder eine gute Anleitung finden🙂 Ich musste einen Arbeiter einstellen, um das System einzurichten. Haben Sie es geschafft, den Gira selbst zu programmieren oder haben Sie einen Spezialisten um Hilfe gebeten?
