《EW-286 》Directions
Welcome to choose our instruments. This product
is a specialize micro-computer temperature
controller for refrigerator and freezer. The panel in
English takes it easy to use and avoid entering
confusing menu represents the parameter setting.
Our sensor is precisely ma-de and sealed. It is
moisture proof, therefore its performances are more
stable and reliable.

Parameters for Procedure

Operating Guide
Parameter settings: press “set” to the “set temp” lighting, each
press “set” key, it will enter to next menu settings (circulating
operation). Enter the menu, press or can change the
program parameters.
Menu settings includes temp setting--
Lower limit ( )--
unction can be
cycled operations. Enter the menu, press or to modify the
corresponding parameters.
Set temperature:
Press ”set” until “set temp” lighting, press or to re-set the
new temperature control (this feature is when the temperature
reaches the set value then machine OFF).
Temperature difference:
Press “set” to enter the menu, scroll to the “D-temp” lights, press
or to re-set the new operating parameters (this function is when
the temperature rises to the set value + return difference, machine
ON).
Operating cycle:
Press “set” to enter the menu, scroll to the “DEF cycle ” lights,
press or to re-set the time interval between two defrost (This
feature is time setting of each operating cycle)
.Defrost time:
Press “set” to enter the menu, scroll to “DEF time” lights, press
or to re-set the new defrost time (this function is working time
of each defrosting)。
Delay time:
Press “set” to enter the menu, scroll to the “Delay time” lights,
press or to re-set the new delay time (this feature is a time
delay before the compressor running, to avoid frequent compressor
start and stop).
Exit temperature:
Press “set” to enter the menu, scroll to “DEF exit temp” lights,
press or key to re-set the new defrost exit temperature.
Temperature correction:
Press and till six lights all lighting, press or to
correct the display temperature value (This feature is when the
temperature error, it can be used for temperature correction by plus
or minus).
High temperature alarm:
Press “set” to enter the menu, scroll to displayed, press or
to re-set the new limit parameters (this function is when the
temperature exceeds set value displayed and alarm output).
Low temperature alarm:
Press “set” to enter the menu, scroll to displayed, press or
to re-set the new limit parameters (this function is when the
temperature exceeds the set value of the lower limit, it will
displayed and alarm output).
Evaporator fan mode:
Press “set” to enter the menu, scroll to displayed, press or
to set the fan normally open (parameter to -1), with the same
start/stop (parameter to 00), delay started (parameter can be set
from 1 to 5 minutes).
Dripping time:
Press “set” to enter the menu, scroll to the displayed, press
or to re-set the time of dripping after defrosting.
Defrost mode:
Press “set” to enter the menu, scroll to the displayed
, press or can set electric defrost or steam defrost (Ex-
factory setting for electric defrost).
