Installer Menu
The Installer Menu allows you to set up and modify system
settings that typically would be adjusted by a trained installer.
These include equipment settings (for boiler operation, DHW
management, zoning, auxiliary input/output operation) and
option settings, such as pump/valve exercise, freeze
protection, and Save/Restore settings.
System statistics and the installer tools (Test and Purge) are
also available from the Installer Menu.
The two Installer Menu options are:
• Equipment Setup (including Statistics) – refer to Table 6
• Test and Purge – refer to Table 7 on page 38
