Controller parameters and operation
Set the temperature setooint
To access the user menu, press and quickly release the "set" key. lf alarms are not present, the label "SEt appears.By using the "uP and 'DOwN keys you can scroll through the other folders in the menu:
-Pb1:probe 1 value folder -SEt Setpoint setting folder. The step of setting the temperature is as below:
When it displays the measured temperature in the display panel,press SET key, it will display Set.
At this time,press SET key you could view the current temperature setpoint.
Press + key or key to modify the setpoint.
Press FNC key it will display the measured temperature, and exit from the temperature setting. lf
high/low temperature alarm happens, user could inquiry alarm type through parameter folders "AL.
Parameter setting
ETC-961 has classifies all parameters into six folders according to the objects and functions: CP、Def.
AL、dis、CnF、FPr,the method to enter the folder is as below:
When it displays the measured temperature in the display panel, press SET key for at least five seconds
it will display the first parameter folder code CR.
At this time,press SET key,it enters the parameter folder CPand it will display the first parameter diF.
Presskey or key. it will display all parameters under the folder of CP in circulation.
If need to view or modify one of the parameters, when it displays the parameter code in the display panel, press SET key to view the parameter setpointand then press . key or s key to modify the setpoint.
restore to disolay the parameter CP
Press FNC it will restore to display the measured temperature value and exit from parameter setting.
Enter the parameter folders of、 Def、AL、diS、CnF、FPr
When it displays the first parameter folder code CPpress key or key, it will display each parameter
folder code in circulation.
Select the desired parameter folder code and press SET key. and it will display first parameter of the
current parameter folder.
The method to view,modify and exit the parameter value will be the same as above.
Manual activation of the defrosting cycle

Other operation is the same as "parameter setting".
Alarm codes
E1: Probe 1 in failure
AH1: High temperature alarm
AL1: Low temperature alarm
NOTE:ETC-961 without the buzzer it will display:(E1) probe errors;(AH1) high tehperature;(AL1)low temperature.
