1）Start delay；
2）Defrosting ；
3）Antifreeze protection；
4）Fault displaying；
5）Screen lock function ；
7-2 Notes about unit running
During the unit running, if the unit is turned off or stops automatically, if restart the unit, the
unit has to wait for 3 minutes to start. This setting is the protection on compressor instead of
fault.
In the heating mode, when the outdoor evaporator surface has white frost (when the air temp
is low or the air is humid, this phenomenon will be more obvious), the heat exchanging and
performance will be affected, so when the frost gets to a certain degree, the system will run the
defrosting automatically.
In the defrosting mode, the outdoor fan motor will stop run. Sometimes there is while vapor
from the outdoor evaporator. Those are normal defrosting phenomenon instead of fault.
In the cold winter, when the unit is standby mode, sometimes it will run the water pump
automatically or even starts the compressor to run for a short time, in order to prevent the
freezing of the water circuit at the low temp. Those are the antifreeze protection operation of
the system instead of fault.
In the cold winter, if the unit is no longer used, please keep the unit energized. Please do not
cut off the power supply, otherwise, it will be impossible to run the antifreeze protection mode
and result in the water circuit freezing and damage on the unit.
If the unit will not be used for a long time, please make sure the water circuit system is
completely drained before cutting off the power supply.
During the normal operation, if the unit suddenly stops, please immediately check the content
displayed on the controller in order to make clear if it is the action of some protective device.
The unit system is set with many protection measures, if there is fault code on the controller
displayer, please immediately contact your dealer or after service support to solve the
problem.
Please refer the fault code table to get the fault meaning.
In the running of the unit, if the controller can’t be operated, please check if the controller
screen is locked. Please refer to the item 7) “screen lock setting” in the part of 5-2.
Please keep the air inlet/outlet surroundings clean, do not block the air inlet/outlet channel in
order to not affect the heat exchanging efficiency.
Set a comfortable water temp instead of over-high water temp, otherwise it will cause the
electricity waste and overload operation of the compressor, possibly also affect the life span of
the unit.
In any case, if the unit has abnormal noise and over vibration, please immediately contact your
dealer or after-sales technician.
If any problem happens during the operation, please contact your dealer or after-sales
technician to solve the problem. Please do not try to dismantle machine or repair the machine
