5 PARAMETER MENU
At the menu page, by touching "PARAMETER", it will back to the parameter setting
page, as shown in the gure below:
1 2
3 4
Parameter (1/2)
WOT Cool: 18°C
WOT Heat: 20°C
RT Cool: 24°C
RT Heat: 20°C
T water tank: 50°C
This menu is used to set the machine adjustment values. The following keys are
used to navigate this menu:
1. Move back to the previous page;
2. Move on to the next page;
3. Go back to the higher level menu;
4. Go back to the main page (Home).
At the menu setting page, by touching the page turning keys, it is able to switch to
the page where the desired parameter is.
After that, this setting will be saved by touching "OK" and then unit will run based
on this setting. While this setting will give up by touching "Cancel".
 Note:
— For parameters with dierent defaults under dierent conditions, when con-
ditions changes, the default value also will change as the corresponding con-
dition changes;
— If the relative function is activated (paragraph "8.1Activating/deactivating the
memory (On/o memory)p.32"), the value of this parameter will be stored in
the memory and automatically reset after any possible voltage failure.
The following table lists all the parameters available, with their functions and op-
erating ranges:
Number Name Displayed name Range (°C) Default
1 Leaving water temperature for cooling (T1) WOT-Cool 5~25°C 18°C

Leaving water temperature for heating (T2) WOT-heat 20~65°C 45°C
3
Room temperature for cooling (T3) RT-Cool 18~30°C 24°C
4 Room temperature for heating (T4) RT-Heat 18~30°C 20°C
5 Water tank temperature (T5) T-tank ctrl. 40~80°C 50°C
6 Leaving water temperature dierence for cooling (t1) T-Cool 2~10°C 5°C
7 Leaving water temperature dierence for heating (t2) T-Heat 2~10°C 10°C
8 Leaving water temperature dierence for water heating (t3) T-hot water 2~25°C 5°C
9 Room temperature control dierence (t4) T-room temp 1~5°C 2°C
10 Temperature dierence between actual and target water for cooling WT-Cool AT -10~0°C -5°C
11 Temperature dierence between actual and target water for heating WT-Heat AT 0~15°C 5°C
12 Temperature dierence between actual and target water for water heating WT-hot water AT 0~15°C 5°C
13 Minimal allowable water temperature by users WT min 5~25°C 5°C
14 Maximal allowable water temperature by users for heating WT-Heat max 20~65°C 65°C
15 Maximal allowable water temperature by users for water heating WT-hot water max 40~80°C 80°C
16 Leaving water temperature setting range for cooling WOT-Cool Range 5~25°C 10°C
17 Leaving water temperature setting range for heating WOT-Heat Range 20~65°C 55°C
19 Leaving water temperature setting range for water heating T-water tank Range 40~80°C 60°C
Parameters from No.10 to No.19 are for setting target water temperature under the
SG function. When SG (Smart Grid) has been activated, the unit after receiving the
grid signal will go under the control as stated below:
Setpoint water temperature
Operating mode Switch-on signal Switch-on command Normal working
Switch-o
command
Cooling
Take the larger between ("WOT-Cool" + "WT-
Cool AT") and "WT min".
Take the larger between "WOT-Cool Range" and "WT min". WOT-Cool /
Heating
Take the smaller between ("WOT-Heat" +
"WT-Heat AT") and "WT-Heat max".
When the electric heater works, take the smaller between "WOT-
Heat Range" and "WT-Heat max".
WOT-heat
/
When the electric heater does not work, take the smaller between
"WOT-Heat Range" and "Tmax". Tmax is the highest leaving water
temperature corresponding to the current ambient temperature.
/
D.H.W.
Take the smaller between ("T-water tank" +
"WT-hot water AT") and "WT-hot water max".
When the electric heater works, take the smaller between "T-water
tank Range" and "WT-hot water max".
T-tank ctrl.
/
When the electric heater does not work, take the smaller between
"T-water tank Range" and "T-HP max".
