Bug Wake UP Danfoss Living Connect by HC2



Hi FIBARO Support

I bought, in December, 4 Danfoss Living Connect (DLC) ZWAVE version 2.5.

I test 2 of ones and I meet a bug, when box HC2 (version V1.044) sends Temperature value to the DLC, manually or with heating panel and schedule heating program.

HC2 tries to wake up DLC ( file in attachment ) , the ZWAVE LED on the box lights up one first time and a second time after 8 seconds briefly but I never see message “Transfer OK” and no information appeared in history panel and no update for temperature value on DLC.

In DLC documentation, DANFOSS specifications say :

After a successful "Inclusion" the controller must send a WAKE_UP_INTERVAL_SET command to living connectR in order to specify where and when living connectR should communicate wirelessly.

▪ After sending the WAKE_UP_INTERVAL_SET command, the controller must assign return routes, so living connectR can reach its destination i.e. the nodeID set in the WAKE_UP_INTERVAL_SET command

This bug is blocking because it prevents no regulation of the heating.

I realize a lot of tests but with no success :

- Exclusion DLC

- Reset Factory DLC

- Inclusion

- Box near DLC (2 meters)

- Wake up manually DLC (push middle button on DLC) and after send temperature value from HC2.

Could you realized tests on these DLC (version 2.5 since December 2012)

Thanks for your response.

However, dialog from DLC to HC2 is OK.

Best regards.

    Hi ASTECH,

    I have 6 of those Danfoss Living connect radiator valves.

    They all work flawless.

    I attached screen shots of a manual change.

    First picture shows the change of the SET temp.

    Second picture the confirmation the Danfoss radiator valve has picked up the new value.

    The third picture the Wake up interval i've set: 10 minutes to save battery power.

    Keep in mind changing SET temp in HC2 only queues the command for the valve in HC2. You need to wait until next wakeup cycle for the valve to pick up this command. Sometimes 2 cycles to get the confirmation.

    rgds, Benno

  • BVD Thanks for your response.

    However in my case, wake up is never efficient , theese 2 Danfoss V2.5 (bouhgt in December) are in installed since 2 weeks directly in V1.044.

    I have restore V1.044 after tests V3.341.

    So may you tell me in what version have you installed your Danfoss.

    On another post , Marcel write

    Posted: Yesterday 15:17 V3.341 installed, want to go back to 1.045, but backups gone

    Well, it's cold in the Netherlands and yes, also in 1.045 Danfoss valves do not work well, but in 3.341 they are a bigger problem... So I want to go back to 1.045, but now I see in the backups screen that all backups have disappeared.

    ASTECH44, you can only saw backups in 1x versions (if you do recovery 1.038 or 1.09 you will see them again)
