Aeotec Radiator Thermostat no pairing with Home Center 3 Lite

[vrsny 0]

Hi,

I have an Aeotec Radiator Thermostat (ZWA021) and a Home Center 3 Lite device. Sometimes, this thermostat dies, it shows as if the batteries were totally empty, but when I remove the batteries and insert them again, they are considered full again and everything works. This time it doesn't work. I insert the batteries, and it says Inc. Based on the manuals it probably means Inclusion, which is probably equal to Learn Mode, as it is called in the Fibaro webapp. If I press the button in the middle a countdown is started from 120 to 0 and then it says Err

 

I removed this device using the Fibaro webapp "Settings > Devices > Remove Device > Force Remove" since I couldn't do anything else with this device. If I try to add it again with "Settings > Devices > Add Device > Z-Wave Device > Start" a 60 second countdown starts and nothing happens. I tried to start the countdown on the thermostat from 120 to 0 before and after I started the pairing in the webapp, but nothing happens, both countdowns reach 0, both devices show failure.

 

What else can I do here?

@vrsny Hello and welcome to the commuity.

 

When use the "Force Remove" button make sure, you have removed the batteries from the aeotec radiator thermostat.

 

I also recommend to reset the thermostat before using this process.
