[mvmlt]

I try to use a AK-RK01S-220-A relay with his 2 buttons remote :

The Domoticz's configuration is OK and the 2 remote buttons are well recongnized.
When I use remote B button, the light is on, when I use remote A button, the light is Off.
When I send order by Domotic, B switch is working well. But A switch do nothing. The reflink order is sent as you can see after :

2016-12 18:42:31.967 User: Admin initiated a switch command (136/A/Off).
2016-12 18:42:31.967 RFLink Sending: 10;Eurodomest;068f9f;5;OFF

Log in rflink loader by using remote :

Button A
20;63;DEBUG;Pulses=50;Pulses(uSec)=870,210,210,840,210,840,840,210,210,840,840,210,840,210,840,210,210,840,210,840,210,840,210,840,210,840,840,210,840,210,210,840,210,840,210,840,210,840,210,840,210,840,840,210,210,840,210,840,210,6990;
20;64;Eurodomest;ID=068f9f;SWITCH=05;CMD=ALLON;

Button B
20;6B;DEBUG;Pulses=50;Pulses(uSec)=900,240,210,840,210,840,840,210,210,840,840,210,840,210,840,210,210,840,210,840,210,840,210,840,210,840,840,210,840,210,210,840,210,840,210,840,210,840,210,840,210,840,210,840,840,210,210,840,210,6990;
20;6C;Eurodomest;ID=068f9f;SWITCH=06;CMD=ALLON;

Is this relay fully compatible with rflink ?
Thank you in advance.
