6. Corresponding Operation Explanation
6.1 About Three-minute Protection
If you re-run the unit or turn on the manual switch after the unit stops, the unit will not start within three
minutes because of the self-protection function of the compressor.
6.2 Auto Adjustment of Fan Motor
If the ambient temperature is high when the unit is operating, the fan motor of the unit might be on the
low-wind operation.
6.3 Defrosting in the Air Supply Operation
When there is frosting during the heat supply, defrosting will operate automatically to improve the heating
effect (about 2-10 minutes).
The fan motor will stop running when defrosting.
6.4 Operating Conditions
For best results from water heater, it is to be operated at outdoor temperatures between -7
℃
~ 43
℃
.
Since there are delicate electronic components inside the unit, it is strictly prohibited to use water from lakes,
rivers or untreated groundwater.
6.5 About Power off
A
All operations stop when the power is off.
B
The operation indicator of the wired controller will flash slowly for several seconds for notifying re-start
after power off.
C
If any error action occurs in the operation (e.g. due to factors such as lightning or radio interference), cut
off the manual power switch, re-start and press the On/Off button again.
6.6 Power-down Memory
The wired controller will memorize the unit state automatically before power-off of the unit or the wired
controller, and send the On/Off signal to the water heater. This ensures that the unit will operate according to
the originally set state when switched on again.
