1.4.4.2 Advanced Setup
Advanced Setup provides access to the full functionality of the system for the
advanced installer. Installers can access and configure the following:
Loads 1-4: Assign load types to up to four Loads. For instructions on
assigning one or more loads, see Settings loads on page 49.
Multiboiler: Set up a boiler to operate as part of a group of boilers (multi-
boilers) at a site. For instructions on how to set up multiple boilers, see
Configuring multiple boiler systems on page 57.
Load Combining: Set up two loads of compatible temperature to run
simultaneously. For information on this feature, see Combining loads on
page 26. For instructions on setting up two loads, see Combining two
loads to service two loads at the same time on page 55.
1.4.4.3 Test Operation
In the "Test Operation" screen, you can test the fan operation and check the venting for any
blockage or leakage. The "Fan Test Heat Out" entry box allows the fan to be activated
independently and set to speeds corresponding to the entered Heat Out value. You can use the
"Fan Test Heat Out" feature when a boiler is not heating. If the boiler is heating, you can check that
the heat output values correspond. For example, for all models (excluding the G3 models), the fan
heat output MBtu should be close to the heat output. For instructions, see Testing the fan operation
on page 69.
1.4.4.4 System Settings
The System Settings screen provides the following options:
Site Settings. Use to access generic boiler operating parameters that
are not specific to a load. Parameters include load control types (pumps
or control valves), boiler pump purge time, manual pump purge, and the
variable speed (VS) output control settings. For instructions, see
Performing a manual pump purge on page 71.
Licensing. Use to activate special add-on software packages such as
BACnet.
Backup and Restore. Use to back up or restore the boiler’s complete
controller configuration and settings to/from a USB memory stick or SD-
card inserted into the controller. For instructions, see Backing up and
restoring a boiler's configuration and settings on page 74.
Software Update. Use to update the controller’s software via an SD memory card, a USB
memory stick or via the Internet. For instructions, see Updating boiler controller software on
page 67.
