5 Star Service
The Danfoss Z-Wave TRV has stopped communicating with VERA. The TRV's alarm-bell and antenna icons are blinking and it will not take commands from VERA.
This is a recent issue and is known as 'Panic Mode'.
By default VERA uses Z-Wave firmware v3.20 , however this version does not include Z-Wave SIS capability, which the Danfoss requires for correct operation.
Change VERA's Z-Wave firmware version to the previous v2.78 version (which does support SIS).
Changing this setting will not adversely affect your system, but will ensure the Danfoss and VERA are able to communicate correctly and reliably
Note : this is valid for older versions of the Danfoss TRV but not for the Danfoss LC-13.
