TOP MOUNT PACKAGED REFRIGERATION SYSTEM

RAPID PARAMETER SET SELECTION (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 activated, the display shows the
corresponding message that flashes alternating with the
temperature; if fitter and enabled, the buzzer and the alarm
relay are also activated.
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/o using the UP
button or by disconnecting the power supply).
NOTE:
■ To restore the selected rapid parameter set at any
time, turn the controller o and on again, while holding
SET. The display 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 parameters.
■ To restore all the parameters and return to the original
default values (factory settings), turn the controller o
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 o when the causes
of the alarm have been resolved. The alarm codes are
shown in the able below:
