Installer Programming Menu

The Installer Menu allows you to set up and modify system
settings that typically would be adjusted by a trained installer.
These include settings such as mixing temperatures limits,
injection, and valve operation.
System statistics, testing, and purging are also available from
the Installer Menu.
Illustrations of the complete Installer Menu begin on page 19.
