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.
10.7.2 COOL MODE SETTING
About COOL MODE SETTING
DHW：domestic hot water
COOL MODE SETTING typically consists of the
following：
COOL MODE: Setting the COOL mode effective or
non-effective
T1S RANGE: Selecting the range of target outlet
water temperature
T4CMAX: Setting the maximum ambient operation
temperature
T4CMIN: Setting the minimum ambient operating
temperature
dT1SC: Setting the temperature difference for
starting the heat pump
How to set the COOL mode
To determine whether the COOL mode is effective, go to
MENU> FOR SERVICEMAN> COOL MODE SETTING.
Press OK.

When the cursor is on COOL MODE, Use
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.
When the cursor is on T4CMAX、T4CMIN、dT1SC、

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:
T1S+dT1SC

COOL
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
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

10.7.3 HEAT MODE SETTING
About HEAT MODE SETTING
HEAT MODE SETTING typically consists of the
following：
HEAT MODE: Enable or disable the HEAT mode
T1S RANGE: Selecting the range of target outlet
water temperature
T4HMAX: Setting the maximum ambient operating
temperature
T4HMIN: Setting the minimum operating ambient
operating temperature
dTISH: Setting the temperature difference for
starting the unit
t_INTERVAL_H: Setting the compressor start time
interval
