T1: Heat pump leaving water temperature

T1S: Heat pump leaving water set temperature

DISINFECT sets whether or not the DHW pump operates during the DHW tank disinfecon operaon.

PUMP RUNNING TIME sets the length of me the pump runs for at each of the user-specied start mes on the DHW PUMP

tab on the DOMESTIC HOT WATER (DHW) menu, if TIMER RUNNING is enabled.

7.5 COOL MODE SETTING Menu

MENU > FOR SERVICEMAN > COOL MODE SETTING

In COOL MODE SETTING the following parameters should be set.

COOL MODE enables or disables cooling mode. For installaons

with space cooling terminals, select YES to enable cooling mode.

For installaons without space cooling terminals, select NON to

disable cooling mode.

Figure 3-7.15: COOL MODE SETTING menu

T1S RANGE selects the heat pump leaving water set temperature range that is available to the user for cooling mode on the

user interface main screen. LOW or HIGH should be selected to suit the type of space cooling terminals installed. When LOW

is selected, the minimum set temperature is 5°C. If the climate-related curve funcon is selected, the curve selected is the

low temperature curve. When HIGH is selected, the minimum set temperature is 18°C. If the climate-related curve funcon is

selected, the curve selected is the high temperature curve. Climate-related curves refer to Mini Heat Pump Monobloc Series

Engineering Data Book, Part 3, 8.1 “Environment Temperature Curves”.

T4CMAX sets the ambient temperature above which the heat pump will not operate in

cooling mode. For M.HP05/07/09 DCI MONO, the highest value that T4CMAX can take

is 43°C. For M.HP12/14/16 DCI MONO, the highest value that T4CMAX can take is 46°C.

T4CMAX is the cooling mode upper ambient temperature operang limit of the heat

pump. Refer to Figure 3-7.16.

dT1SC sets the minimum temperature dierence between the heat pump leaving

water temperature (T1) and the heat pump leaving water set temperature (T1S) at

which the heat pump provides chilled water to the space cooling terminals. When T1

– T1S ≥ dT1SC the heat pump provides chilled water to the space cooling terminals

and when T1 ≤ T1S the heat pump does not pro water to the space cooling terminals.

dTSC sets the temperature dierence between the actual room temperature (Ta)

T4: Outdoor ambient temperature

T4CMIN sets the ambient temperature below which the heat pump will not operate in cooling mode. The lowest value that

T4CMIN can take is -5°C, which is the cooling mode lower ambient temperature operang limit of the heat pump. Refer to

Figure 3-7.16.

and set room temperature (TS) above which the heat pump provides chilled water

to the space cooling terminals. When Ta – TS ≥ dTSC the heat pump provides chilled

water to the space cooling terminals and when Ta ≤ TS the heat pump does not

provide chilled water to the space cooling terminals. Refer to Figure 3-7.18. dTSC is

only applicable if YES is selected for ROOM TEMP in the TEMP. TYPE SETTING menu.

Refer to Part 3, 7.8 “TEMP. TYPE SETTING Menu”.
