HmIP-FAL Connection failure with room control unit

[samuellazea]

Hi all,

I would like if possible to get some wisdom from you. I have an entire system for heating that contains FAL, WTH-2, PSM, WRC2, MIOB, FSM etc.

Currently I did a change in the system that I installed FSM to control the actuator pump myself and not by automatic pump channel 1 on the FAL. Before I had the FAL channel 1 ( pump) connected to a thermostat and that worked ok but now since I removed the pump from the FAL, I deleted the link to the thermostat and connected the pump directly to the FAL.

The problem that I can't figure out is after deleting the link from WTH-2 to FAL channel one, I have the FAL channel 1 always in error saying "Connection failure with room control unit". I did check that I have no direct link now but somehow he is still thinking some link is there. I also made sure the channel 1 is not assigned anymore to pump control.

I am posting some screenshots for more info.
Any help would be much appreciated
