more than 5 seconds, the current real-time clock setting value
will be confirmed and returned to the main interface.
TIME PERIOD SETTINGS
1. The three default time periods are 09:00-17:00, 00:00-18:00,
00:00-00:00.
2. In the main interface, press the button “ ” for 3 seconds to enter
or exit time period setting.
3. In the time period setting interface, click the button “ ” to switch
the hour and minute of the start time and end time, also click the
button “ ” to switch time period 1, 2 and 3.
4. The value is flashing when switching to the corresponding value
of the time period. Meanwhile the icon “ON” or “OFF” is flashing,
Press "
∧
” or “
∨
” to increase or decrease the corresponding value.
Press the button “
” or no operation in 15 seconds, the setting
will be saved and the controller will return to the main interface.
5. In the time period setting interface, the corresponding icon ON
will be displayed if the corresponding time period is set, the
corresponding icon OFF will be displayed if the corresponding
time period is not set.
6. The system will only work during the time period if it is set.
7. If the start time is same as the end time, it will canceling this timing
period.
8. If all 3 timed periods are canceled, system is allowed to work
anytime.
9. If the start time of time period is later than the end time, the end
time is considered to be the 2nd day.
ELECTRIC HEATER CONTROL
BOOSTER MODE
1. To turn on/off electric heating element Press both buttons“
”+“
” simultaneously for more than 3 seconds.
2. The electric heating element will heat the water to the set
temperature.
3. The icon "
" keeps constantly bright during Booster mode,
also the heat pump will stop running.
ELECTRIC HEATER MODE
1. If the following issues happen, the electric heating element will
be activated if water requires heating:
•
High pressure alarm
•
Low ambient temperature mode
•
High ambient temperature mode
•
High gas exhaust temperature alarm
•
Gas exhaust temperature sensor failure
•
Gas return temperature sensor failure
2. Under manual mode for water temperature setting, the working of
electric heating element is decided by water setting temperature
and dead-band temperature.
3. Under Auto mode for water temperature setting, the working of
electric heating element is decided by water temperature and
ambient temperature, please see following table:

HIGH TEMPERATURE MODE
1. When ambient temperature ≥ 43°C (it can be adjusted by F86), the
heat- pump will stop running. The system will activate the electric
heating element to heat the water instead until the temperature
recovers to the normal range.
2. When ambient temperature ≤ 41°C, the electric heating element
will stop running. The system will activate the heat pump and run in
standard conditions..
3. Under low temperature mode, the working of electric heating
element is decided by water setting temperature and dead-band
temperature.
LOW TEMPERATURE MODE
1. When ambient temperature ≤ -7°C (it can be adjusted by F10), the
heat pump will stop running, also the electric heating element will
start to work if necessary.
2. When ambient temperature is ≥ -5°C the electric heating element
will stop working. The heat pump will run if necessary.
3. Under low temperature mode, the electric heating element starts
or stops working which is decided by water setting temperature
and dead-band temperature.
