Over probation time
If you have set the probation time F87, the alarm occurs when the accumulative running
time is over probation time, and the controller can not work.
% 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 temperature, then using “” key or “” key can change the parameter（the
key“”adds 0.1°C, the key“”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 advanced 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 outdoor temperature?
When displaying current temperature, press “” key, Controller will display defrosting temperature.
Loose “” key, then return to current temperature. Notice that if you press the key and hold it for 5
seconds, the controller will enter or exit the defrosting state forcibly.

key “” and “” to adjust the value, then press the key “Set” again to exit. Pressing the key “M” in the
adjusting process means giving up and exiting, but the time will not be saved.
% How to heat forcibly?
When displaying current temperature, the temperature is between “setting temperature－temperature
difference” and “setting temperature＋temperature difference”, the system may or not heat, here you
press the key “” and hold it for 5 seconds, the controller will enter the heat state forcibly when in the
heat state, and stop heating when the temperature is above “setting temperature＋temperature
difference”.
& 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 “↑” and “↓” to enter the password, if the

，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.
