SETUP OF THE SYSTEM
To determine whether the COOL mode is effective, go to
MENU> FOR SERVICEMAN> COOL MODE SETTING .
Press OK . The following page will be displayed:
When the cursor is on COOL MODE, Use ◄► to select YES or NON. Then press OK to enable or disable the cool mode. When
the cursor is on T1S RANGE. Use ◄►to select the range of outlet water temperature. When LOW is selected, the minimum
target temperature is 5°C . If the climate-related curve function (corresponds to “weather temperature set” in the user interface)
is enabled , the curve selected is the low temperature curve . When HIGH is selected, the minimum target temperature is 18°C, if
the climate-related curve function (corresponds to “weather temperature set” in the user interface) is enabled, the curve selected
is the high temperature curve .
When the cursor is on T4CMAX,T4CMIN,dT1SC,dTSC or t_INTERVAL_C, Use ◄► and ▼▲ to scroll and adjust the parameter.
T4CMAX is the maximum outdoor air temperature in COOL mode . The unit cannot work if the outdoor air temperature is higher .
T4CMIN is the minimum outdoor air operating temperature in COOL mode . The unit will turn off if the outdoor air temperature
drops below it . The relationship between the operation of the unit and outdoor air temperature is shown in the picture below:
dT1SC is the temperature difference between T1 (actual outlet water temperature)
and T1S (target outlet water temperature) for starting the unit in cool mode . Only
when T1 is high enough will the unit turn on, and will turn off if T1 drops to a certain
value . See the diagram below:
dT1SC is the temperature difference between T1 (actual outlet water temperature)
and T1S (target outlet water temperature) for starting the unit in cool mode . Only
when T1 is high enough will the unit turn on, and will turn off if T1 drops to a certain
value . See the diagram below:
dTSC is the temperature difference between Ta (actual room temperature) and TS
(target room temperature) To start the unit when ROOM TEMP is enabled in TEMP .
TYPE SETTING (refer to10 .7 Field setting/TEMP .TYPE SETTING) . Only when the
Ta is high enough will the unit turn on, and the unit will turn off if the Ta drops to a
certain value . Only when the ROOM TEMP is enabled will this function be available .

COOL mode setting
COOL MODE SETTING typically consists of the following:
1 . COOL MODE: to set if the COOL mode is active or not
2 . T1S RANGE: Selecting the range of target outlet water temperature
3 . T4CMAX: Setting the maximum outdoor air operation temperature
4 . T4CMIN: Setting the minimum outdoor air operating temperature
5 . dT1SC: Setting the temperature difference for starting the heat pump
6 . t_INTERVAL_C: to set the compressor stop time before the next start in cool mode
If COOL MODE is set "NON", the function is not available and so could not be selected by the user .
