6.2 Non-unit related faults
The following fault symptoms are not caused by the unit itself:
1) Fault symptom: Fan speed is not consistent with the setting
The fan doesn't respond to the controller. In Cool mode, when the pipe water temperature exceeds the allowable range of room
temperature, the fan speed will be maintained at a low level to avoid direct exposure to hot air. In Heat mode, when the pipe
water temperature reaches a certain low level, the fan speed will also be maintained at a low level to avoid direct exposure to
cold air.
2) Fault symptom: Fan direction is not consistent with the setting
The fan direction is inconsistent with that indicated on the user interface. Swing is a customized function. When Swing is
enabled but the fan direction does not change accordingly, it is because the unit is responding to other control instructions.
3) Fault symptom: white fog from a certain unit
This may result from high humidity during cooling operation. If the fan coil interior is dirty, the indoor temperature distribution
may be uneven. At this time, you need to clean the inside of the unit. Ask the dealer for information on how to clean the unit.
This operation must be carried out by qualified maintenance personnel.
4) Fault symptom: dust and dirt in the unit
This may happen after the unit is used again after being left idle for a long period. This is because there is dust inside the unit.
5) Fault symptom: odour from unit
The unit will absorb odours of rooms, furniture, cigarettes, etc., and then disperse the odours. Odours might occur after small
animals enter the unit.
