Danfoss 014G0002 - Doesn`t work

[hasan]

HI,

maybe i bought wrong valve

I have 014G0002 with SW4.02... and OpenZwave is showing: Danfoss Unknown: type=8005, id=0002

and it doesn`t work is there any way how it should work?

In brief: no, it won't work

F*ck.... I s there any way how to downgrade firmware in Danfoss valve? It should be a way...

No, there's no way. You have need the correct version (the ones with ending number 13).

OK... thanks... API for Danfoss LINK CC is not available so integration into Domoticz is not possible...

Not so fast.

If the hardware is the same, you should be able to reflash the TRV with other software. I'm currently trying this for my TRVs (danfoss 014G0013 or thereabouts). I want to transplant the popp code onto the original danfoss TRVs. Just got the AVR-ISP-MK2 programmer working. Finding the right connection for the PCB was easy. Will keep you posted.

What's the point flasing a different software into a different model? AFAIK Popp's hardwaree is different (there's a built-in thermometer). So you won't get anything, because your hardware doesn't contain the thermometer. Besides, your warranty will be void, etc. Third: I really do think that OP's hardware is a bit different than the one with 13 ending).

AFAIK Popp's hardwaree is different (there's a built-in thermometer).

It's exactly the same device (just doesn't have danfoss embossed in the housing). Same hardware, same microcontroller, just a different brand name (ZWE at the inside, popp on the box and accompanying booklet). The danfoss LC-13 also has the same built-in temperature sensor, it's hard for a TRV to control a temperature if it doesn't know what it actually is.

Then good luck for the reflashing - still, it's not something an average user can achieve. But now I understand your point (and sorry for being a bit sarcastic on the hardware thing)

Just had a look at the flash settings. It's not going to happen any time soon; the code's locked inside the microcontroller, no way to get it out .

Then I was right - it's ALMOST impossible (at least for an average user) to change/reflash the firmware
