flect the settings in the ordering guide. The factory settings are protected by an access
code (initially 0) that can be changed.
● The user or the integrator is responsible for changing the pump parameters according
to the requirements of the application.
HHR mode is active when the ‘Keyboard’ control mode is configured by the HHR or the RS-232/RS-485
serial link.
