Rapid Parameter Set Selction (EZY)
The easy controller features the EZY parameter which is used to
quickly choose a list of parameters, with corresponding values, for
the control of the refrigeration system.
Table of Alarms and Signals
When an alarm is activiated, the display shows the corresponding
message that flashes alternating with the temperature; if fitter and
enabled, the buzzer and the alarm relay are also activiated.
All the alarms have automatic reset (that is, they stop when the
causes are no longer present), except for alarm 'CHt' which has
manual reset (instrument on/off using the UP button or by discon-
necting the power supply).
NOTE:
• to restore the slected rapid parameter set at any time, turn the
controller off and on again, while holding SET. The desplay shows
"CE" to indicate that the selected rapid set (EZY= 1, 2, 3) has again
over written the operating parameters, thus restoring the original
set of paremters;
• to restore all the parameters and return to the original default
values (factory settings), turn the controller off and on again
while holding DOWN and SET, until the display shows "CF". Use
this procedure with extreme car, as it may compromise the
fundamental control settings;
• EZY= 0 brings no change
Pressing the SET button mutes the buzzer, while the code displayed
and the alarm relay only go off when the causes of the alarm have
been resolved. The alarm codes are shown in the able below:
