FOUND MODULS
Display of heat generators automatically
reported via BUS with BUS ID. Displays the
number of heat modules available for service.

CAP/MODULE
After restarting, the Controller, searches the bus
systems for available new heat modules and the
maximum kW output of each heat module.

NEW CONFIG
If the BUS configuration was modified, the
automatic search for generators on the BUS may
be activated here.
