NOTE:
In operating, press the key "CANCEL", to turn back to the previous step or the normal display interface.
1.Before power failure of the heating water system or wired controller, the wired controller memorizes the
status of the unit automatically, and sets the water temperature value except timing on/off function. After being
powered on, the wired controller will send the relevant signals to the heating water system according to
memorized status before power failure, in order to ensure that the unit can run in the originally set status after
restoration of the power supply.
2. In the normal status, the background light is off. Press any key can only turn on the background light .
3. In order to protect the equipment, it is not allowed to change the running mode quickly or frequently. It
should operate the wired controller to start up the unit after 3 minutes later or all units are shutdown.
4. The wired controller and the outdoor unit must connect with the same power supply, powered up and
powered off simultaneously. It is not allowed to cut off the power supply separately.
5. When several wired controllers are parallel co
nnected, the timing message can’t communicating in these
wired controllers, and the timing will work separately. In order not to confuse, we suggest set the timing
message on one wired controller for the reason of indoor unit performance is compliance with the sequence
of setting time.
6.During changing or installing the battery, pay attention to the “+”,“-” poles of the battery and install it correctly,
or will damage the control panel or battery, even worse will put lives at risk.
