Installation, Operation & Maintenance Manual
5.1 Installation Menu: Initializing the E8 Controller
Each time power is applied to the boiler and the E8 controller cover (Figure 4-1) is opened, the 
INSTALLATION Menu is displayed once (only). These values MUST be entered in order to 
initialize the boiler for operation. Once the values grouped here have been entered and 
accepted, the controller is initiated and operatable and may be configured for your boiler 
installation. To re-enter the INSTALLATION menu, cycle the boiler power and open the cover 
again. 
To initialize the E8 Controller, set the following values in the INSTALLATION Menu:
• Set the parameters: ENGLISH, HOUR, YEAR, MONTH, and DAY.
• Leave the BUS – ID HS parameter blank.
• Remaining parameters are already set and do not require any entry.
