Recovery Time
Defrosting during Water-heating
If the evaporator freezes over in Economy Mode and Hybrid
Mode during cold weather, the system will defrost automatically
to keep effective performance(3~10 min).
In defrosting mode, the fan motor will run at a high speed and
E-Heater will operate.
Ambient Temperature
The systemʼs operational temperature is between -20℃~43℃
The following are the operation temperatures for each mode.
Economy Mode: 5℃~43℃
Hybrid Mode: -20℃~43℃
E-Heater Mode: -20℃~43℃
Mode Selection
The different modes are designed to meet different demands
and the following are recommended selections.
Economy Mode: 5~43℃, a continuous hot water demand below
150L(65℃);
Hybrid Mode: -20℃~43℃, a continuous hot water demand
between 150L~200L(70℃);
E-Heater Mode: -20℃~43℃, a continuous hot water demand
between 150L~200L(70℃).
Self-Protection Apparatuses
When the self-protection occurs, the system will be stopped and
will begin self-check, and restart when the protection resolved;
When the self-protection happens, the buzzer will buzz in every
other minute, the ALARM indicator will flash and the display will
indicate the error code and water temperature alternatively.
Press CANCEL key for 3sec to stop the alarm. All stop when the
protection is resolved and error code disappears from the
display.
In the following circumstances, self-protection starts:
Air inlet or outlet is blocked;
The evaporator is covered with too much dust;
Incorrect power supply (exceeding the range of 220-240V)
NOTE
When self-protection happens, cut the power supply manually
and restart after the error resolved.
