Initial Power-up
Immediately following power-
up of the boiler, the system will go through a process of “Device Discovery”, where the devices
connected to the boiler are discovered. This is followed by an “Initializing” process.
Figure 16-1 Initial Power-up
After device discovery and initializing, the controller performs an air purge sequence that is designed to purge air from the
boiler water. The air purge sequence cycles the circulators off and on, for a period of 8 minutes, to help free air pockets that
may exists in the heat exchanger and boiler piping.
The air purge sequence is only initiated following the first power-up of the boiler (or via the
menu); if air has already been adequately purged from the system the sequence can be
stopped by pressing Cancel, see Figure 16-2.
The air purge sequence is designed to remove air from the system; failure to adequately remove air
from the system can damage the heat exchanger and void the warranty and may lead to property
damage and personal injury.
