A. CONTROL OVERVIEW
The control is one of the primary safety devices of the boiler. It monitors the boiler safety sensors to assure safe and efficient operation,
and has the capability to lock out and halt boiler operation when a fault or error is detected.
Also, the control has many features associated with hydronic design. By properly customizing boiler operating parameters, the installer
can provide safe, efficient heating and domestic hot water to the end user.
B. MENU STRUCTURE
After the display has established communication with the main board, the installer will be able to use the display to navigate through the
boiler menu structure. That structure is summarized in Figure 29.

C. NAVIGATION OF THE DISPLAY
The control features a four line LCD display to provide informative messages about the operation of the boiler. Six navigation and
operation keys allow the user/installer to view and adjust many boiler operating parameters. Two LED lights inform and alert the
user/installer to Cascade status and possible operating issues.
The following describes how to navigate control parameters using the display.
