Factory settings
The controller is pre-configured for operation. However, the settings should be customized to the user's
needs. Return to factory settings is possible at any time. When the factory settings option is activated,
all customized settings of the CH boiler (saved in the user's menu) are lost and replaced with the
manufacturer's settings. Then, the parameters may be customized anew.
