EC1-233 Display Case and Coldroom Controller
Operating Instructions
GB
Parameter Modification: Procedure
• When the Prg LED is illuminated the parameters may be modified and the first
parameter “St” will be displayed.
• Press the Prg button again to display the current value associated with the
parameter.
• Press
or to increase or decrease the value. Pressing either button for 3
seconds will increase the speed of value change.
• Press the Prg button again to display the current parameter; “St”
• Press
repeatedly to show the next parameter code to be changed;
• Press the Prg button again to display the current value associated with the
parameter and the
or to increase or decrease the value.
• Repeat the procedure from the beginning "press
repeatedly to show..."
To exit and save the new settings:
• Press Prg for 3 seconds to confirm the new values and exit the parameters
modification procedure. The Prg LED will be turned off.
• Alternatively avoid pressing any button for at least 15 seconds and the controller
will automatically revert to the operation mode; controller “times out”.
• If any parameter is modified and the controller then times out, the new setting
will be automatically saved.
Copy Key Procedure
Upload procedure:
• With the controller powered, plug the copy key into the mini USB.
• Press the
button and the controller will display “UPL”.
• Press the PRG button to start the upload process to the copy key.
• Turn 230V power off before removing the copy key from the controller.
Download procedure:
• Turn 230V power off before inserting the copy key into the controller.
• Turn 230V power on. The controller will automatically detect the copy key is
present and start downloading the stored parameters into the controller. “DOW”
will be displayed on the controller during downloading process.
• Turn 230V power off before removing the copy key from the controller or the
data will be corrupted.
• Turn 230V power on and check the parameter values following the parameter
modification procedure above.
Caution:
DO NOT turn the controller off during this process. The control temperature will
be displayed when the process has been completed. ”Err” will be displayed if there
is an error during the upload/download procedure.
Any attempt to download a second set of parameter into the copy key will
automatically overwrite the original set.
Defrost Activation:
A defrost cycle can be activated locally from the keypad:
• Press the button for more than 3 seconds, the defrost cycle is activated and
the defrost LED will be illuminated (only if S5< value of parameter dt).
Continuous Cooling Demand Activation:
The controller can be set to continuous cooling:
• Press
the button for more than 3 seconds, the controller will be forced into the
cooling mode and the cooling LED will be illuminated.
• Press
the button for more than 3 seconds again to stop the continuous cooling
process.
Display of Data:
During normal operation, the display will show the temperature measured by the
S1 air sensor.
Press
to display the current value associated with the defrost termination sensor.
LED displayed when:
Parameter alteration mode is active.
Compressor / Cooling relay active
Defrost heater relay active
Fan relay active
Note: A blinking LED indicates the respective relay is inhibited from becoming
active due to a time delay or an active alarm condition
