How to set the Heat mode
To determine whether the HEAT mode is effective, go to
MENU>FOR SERVICEMAN> HEAT MODE SETTING.
Press OK. The following page be displayed:
T4CMAX is the maximum ambient temperature in COOL
mode. The unit cannot work if the ambient temperature is
higher.
T4CMIN is the minimum ambient operating temperature
in COOL mode. The unit will turn off if the ambient
temperature drops below it.
The relationship between the operation of the unit and
ambient 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:

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. See picture
below:

10.7.2 COOL MODE SETTING
When DISINFECT is ON, the DHW pump will operate
when the unit is in disinfect mode and T5≥T5S_DI-2.
Pump run time is PUMP RUNNING TIME+5min.
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 climate-related curve function (corresponds to
“weather temperature set” in the user interface) is
enabled , the curve selected is low temperature curve.
When HIGH is selected, the minimum target temperature
is 18°C, if climate-related curve function (corresponds to
“weather temperature set” in the user interface) is
enabled, the curve selected is high temperature curve.
