WARNING!
When going into parameter P1, the controller will reset
the maximum temperatures (MT) detected until that
moment. Furthermore, when quitting this parameter,
the controller will set again the temperature display
on the sensor S_1.
The thermal parameters to be set are displayed when
the relevant scheme is selected, this means the power
unit will only display the thermal parameters actually
activated for the selected hydraulic scheme.
P1: SELECT INSTALLATION TYPE
Pressing the ‘ S ‘ or ‘ T ‘ keys will show all the installations
that can be set up (if the probe for the selected installation
has a problem or is left unconnected that probe will ƀash on
the display). To conſrm the selected installation press the ‘
‘ key; the control unit will memorize the choice and the display
will again show the parameter list.
To cancel the selection press the ‘ esc ’ key. In this case the
control unit will abandon the changes made and will show
again the parameter list.
The parameters inƀuencing the regulation of the selected
setup are listed in the following and can be modiſed through
the second installer parameter (P2).
