9.17 Factory Menu
Inappropriate changes to parameters in the Factory Menu could result in a unit or system
malfunction.
For this reason, only a qualified technician who has in-depth knowledge of the unit
should make any changes to the parameters in this menu. The parameters available allow the
unit to be configured and set for proper operation.
The Factory Menu for boilers and water heaters are different from one another, so there are
separate columns showing the settings for each in the chart below.
To enter the Factory Menu, perform the following steps:
