instrument goes to the refrigeration stage.To activate this mode, press the digital input
button for 3 seconds.In this mode the temperature displayed on the display is alternated
with the

message, all alarms are ignored and the control outputs are switched
off, except for the fans output remaining on for the time set in this function.
Note: This mode has priority over other control functions of the instrument, except
for the control functions shutdown.

Enable second defrost output
With this function activated, you can make the output FAN operate as a second defrost
output. This output is activated during the execution of the pre-defrost, defrost and
drainage.

Fan operation when opening the door
The fan can be set to remain activated or deactivated during the period when the door is
kept open.
Fan deactivation by high temperature in evaporator
The purpose of this function is to stop the evaporator fan until the room temperature
approaches that listed in the project, thus preventing a high temperature and suction
pressure which can damage the compressor. If the evaporator temperature surpasses
that of the value, the faz is turned off, turning back on with a set hysteresis of 2°C/4°F. It is
a valuable resource when, for example, cooling equipment has been inactive for a few
days or when freezer rooms or refrigerated counters are refilled with stock.
After drainage, the fan’s delay cycle is enabled. The compressor is immediately turned on
because the evaporator temperature is high, but the fan is only enabled after the
evaporator temperature decrease to the set programmed value. This process is required
to remove residual heat (caused by the defrosting process) in the evaporator, preventing
room temperature to rise.
Evaporator temperature for fan reactivation after
draining
For safety, in case the evaporator temperature does not reach the value in

the sensor S2 is disconnected, fan reactivation will occur after the function’s set time.

DESCRIPTION
FUNCTION
Door open time until instant defrost begins
If the door is kept open for a longer period than set with this function, an instant defrost will
take place, provided that the evaporator temperature (sensor S2) is lower than
[,f34]
,
[,f35]
,
[,f36]
and the room temperature (sensor S1) is lower than
[,f37]
,
[,f38]
,
[,f39]
.
Door open time until compressor and fan are turned
OFF
For safety, if the time that the door is kept open is greater than that set with this
function, both the compressor and the fan will be turned off.

Time of door closed for turning the lights off
This setup defines when the light will be turned off with the door closed. It contributes
towards power saving.
Time of door closed for activation of power-saving
mode
This setup defines when power-saving mode will be activated with the door closed. The
light output will be deactivated if it is ON and the operation setpoint will control the system
according to the power-saving setpoint.
Maximum time on power-saving mode with the door
closed
This allows you to set a maximum operating time for power-saving mode while the door is
closed. After this time, the setpoint returns to the normal operating mode. This time is
calculated in hours.
Time of closed door for activation of antifreeze
safety differential temperature
This function aims at preventing products from freeze after a period of closed door.
Minimum time with compressor OFF
Minimum time with compressor ON
This is the minimum time the compressor will remain turned off, i.e. time between its last
deactivation and the next activation. It helps to relieve the discharge pressure and
increase the lifespan of the compressor.
This is the minimum time the compressor will remain on, i.e. time between the last
activation and the next deactivation. It helps to prevent high voltages within the power
grid.
