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.
DHW PUMP DI RUN sets wether or not the DHW pump (eld supply) operates during the disinfecon mode.
8.5 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.
t_T4_FRESH_C sets the refresh me of cooling mode climate temperature curve.
T4CMAX sets the ambient temperature above which the heat pump will not operate
in cooling mode. The highest value that T4CMAX can take is 46°C, which is the cooling
mode upper ambient temperature operang limit of the heat pump. Refer to Figure
3-8.11.
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 3-8.12.
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 provide chilled water to the space cooling terminals.
dTSC sets the temperature dierence between the actual room temperature (Ta) 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 3-8.18. dTSC is only applicable if
YES is selected for ROOM TEMP in the TEMP. TYPE SETTING menu. Refer to Part 3 8.8
TEMP. TYPE SETTING Menu”.
t_INTERVAL_C sets the cooling mode compressor re-start delay. When the compressor
stops running, it will not re-start unl at least t_INTERVAL_C minutes have elapsed.
