I've hook up system with 2 zone damper with 2nos Brivis networker wall controller. And programed one as master and other slave controllers. System run but can't activate the zone dampers and also no zone display on the panel key 4/5 with parameter value 2. I am using 240v damper motor with 24vac nc/no relay. And both connected to zone A and B n/o terminals .
