Be aware that the domestic hot water temperature at the hot water
tap will be equal to the value selected in FOR SERVICEMAN
"T5S_DI" after a disinfection operation.
WARNING
If this high domestic hot water temperature can be a potential
risk for human injuries, a mixing valve (field supply) shall be
installed at the hot water outlet connection of the domestic hot
water tank. This mixing valve shall secure that the hot water
temperature at the hot water tap never rise above a set
maximum value. This maximum allowable hot water temperature
shall be selected according to local laws and regulations.

SCROLL
The function of the DHW PRIORITY is used to set the operation
priority between domestic water heating and space (heating/
cooling)operation. You can use◄、►、▼、▲ to scroll and
adjust parameters.Using BACK to exit.
T_DHWHP_MAX is the maximum continuous working period of
heat pump in DHW PRIORITY mode.
T_DHWHP_RESTRICT is the operation time for space heating/
cooling operation.
If DHW PRIORITY is enabled, the operation of the unit can be descri-
bed in the picture below：
If NON is selected in DHW PRIORIT , when is available and the
space heating/cooling is OFF, the heat pump will operate to heat the
domestic hot water(when domestic water heating is needed); if the
space heating/cooling is ON, the will operate to heat the domestic hot
water(when domestic water heating is needed).
when booster heater is unavailable, only when the space
heating/cooling is OFF will the heat pump operate to heat the
domestic hot water.

When the TIMER RUNNING is ON, the DHW pump will run as timed
and keep running for an certain time t(as defined in PUMP
RUNNING TIME).
When DISINFECT is ON, the DHW pump will operate when the unit
is in disinfect mode and T5≥T5S_DI-2, the time that the pump keep
running is t+5min.
6.9 COOL MODE SETTING
■ About COOL MODE SETTING
COOL MODE SETTING typically consists of the following：
1. COOL MODE: Setting the COOL mode effctive or not
2. T1S RANGE: Selecting the range of target outlet water temperature
3. T4CMAX: Setting the maximum operation ambient temperature
4. T4CMIN: Setting the minimum operation ambient temperature
5. 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.
The following page will be appear：

SCROLL
When the cursor is on COOL MODE, Using ◄、► to select YES or
NON, then press OK to enable or disable the cool mode, When the
cursor is on T1S RANGE, Using ◄、►to select the range of target
outlet water temperature. When LOW is selected, the minimum
target temperature is 5°C， if climate related curve function
(correspond 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 （correspond 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、dTSC or
t_INTERVAL_C, Using ◄、►、▼、▲ to scroll and adjust the
parameter.
T4CMAX is the maximum operation ambient temperature in COOL
mode. The unit can't work if the ambient temperature above it.
T4CMIN is the minimum operation ambient temperature in COOL
mode. the unit will turn off if the ambient temperature drop below it.
The relationship between the operation of the unit and ambient
temperature can be illustrated in the picture below:
