4. MODE 4: Solar High Mode
Only works when the heat pump is on. The heat pump enters the solar high mode, the main screen
of the display shows solar high mode.
1. In heating mode: The operating target temperature = The setting target tempe parameter [SG06]
2. In cooling mode: The operating target temperature = The setting target temperature - parameter [SG07]
3. In hot water mode, The operating target temperature = The setting target tempe parameter
[SG05]
Note:
When there is no hot water demand, the heat pump will automatically raise the target temperature
of hot water to ensure that it can automatically switch to hot water mode to use the hot water tank
storage heat during that time.
4. In Mode 4 mode, Whether to allow electric heater on can be selected by parameter.
If enable the electric heater in mode 4 mode, the electric heater will turn on immediately, which
is to convert electric energy into thermal energy for storage during the shortest time when the
sunlight is strongest.
Note:
Considering the safe operating range, in this mode the heat pump is limited by the curve of the
maximum water temperature.
Note:
1. Compensation temperature for Mode 4:
There are four control options for automatic start/stop of heat pumps:
H25=3 [Buffer tank temperature];
H25=2 [Inlet water temperature];
H25=0 [Outlet water temperature];
H25=1 [Room temperature];
When H25=1, the temperature compensation in solar high mode only works for the outlet water
temperature.
When H25=3/2/0, the temperature compensation in solar high mode works for the temperature
set by H25 parameter.
When enable multi-zone control function and H25≠1, the temperature compensation in solar high
mode works for the temperature set by H25 parameter.
