(Ec43 and Ec44).
Press the key to view the variables (suction temperature, evaporation pressure, superheating
value, etc.) of valve 1 or valve 2. The icons, which represent the state of the valve (icon ON if
the valve is adjusting), are always displayed, even if the currently displayed variables are those of the
other valve.
If the variables of valve 1 are shown on the display, only the icons belonging to valve 1 are viewed (V1,
, open, close), except for the status icon ( ).
If the variables of valve 2 are shown on the display, only the icons belonging to valve 2 are viewed (V2,
, open, close), except for the status icon ( ).
The alarms are shown in the lower display, regardless whether they belong to valve 1 or 2. The alarms
are shown alternately with the value that appears in the lower display under normal conditions. If the
probe that is to be displayed is in error, "----" appears instead of the value.
