INFORMATION When digital input adapter BRP7A5* is part of the system, it is not possible to connect a second controller. Connecting a second controller when the system already contains the adapter will cause the adapter to go into error mode. If a sub controller does not display the home screen 2 minutes after its designation, turn off the power and check the wiring. INFORMATION INFORMATION After re-designating a controller, the system requires a power reset. The following functions are not available for sub controllers: • “Auto” operation mode • Individual airflow direction • Filter auto clean • Setback temperature setpoints • Draft prevention INFORMATION 17
