TECHNICAL MANUAL. START-UP AND OPERATION
Press the key "set" for at least 2 seconds, then enter the state of temperature setting, here the LED displays the setting temperature, then
using "
" key or "
" key can change the parameter (the key "
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.
When displaying current temperature, press " " key, Controller will display defrosting temperature. Loose " " key, then return to current
temperature.
Advanced Operation
Press the key "M" and hold it for
you can use the key " " and " " to enter the password, if the password is correct, the LED will display the parameter code, use " "
or " " 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 " " or " " 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.
