TECHNICAL MANUAL. START-UP AND OPERATION
How to set the temperature?
Press the key “set” for at least 2 seconds, then enter the state of temperature setting, here the LED displays the setting tempera-
ture, then using “5” key or “6” key can change the parameter (the key “5” adds 0.1°C, the key “6” minuses 0.1°C,
press and hold it over 0.5 seconds can add or minus rapidly). After setting, press “set” again, then exit the state of parameter
setting. (The setting temp range is limited by the parameters F13 and F14; please refer to the senior operation). Pressing the key
“M” in the setting process means cancel and exit, but the setting value will not be saved.
How to read the temperature of the evaporator sensor?
When displaying current temperature, press “6” key, Controller will display defrosting temperature. Loose “6” key, then return to
current temperature.
Advanced Operation
Press the key “M” and hold it for 5 seconds, and if you have set the password, the LED display the “PAS” to hint you to enter the
password, you can use the key “5” and “6” to enter the password, if the password is correct, the LED will display the
parameter code, use “5” or “6” to select the parameter code. Pressing the “set” key can make it to show the value of the
parameter after select the parameter, here you use “5” or “6” to set the parameter (pressing the key and not release can add
or minus rapidly), then press the “set” key to return to the state of showing parameter code after finishing setting. Pressing the key
“M” can exit the parameter setting state when display the parameter code, pressing the key “M” means cancel when in the process of
setting parameter, and the parameter will not be changed.
Internal parameter code is showing bellow:
Sort Code Parameter Name Range Factory setting

The setting range is limited
by F13 and F14

Notice: the controller will
follow the rule of
F14<F11<F13 forcibly, if
you find out that one
parameter can not be
adjusted, it is because the
parameter is limited by other
parameters, you must first
adjust other parameters
