dTSH sets the temperature dierence between the actual room temperature (Ta)
and set room temperature (TS) above which the heat pump provides heated water
to the space heang terminals. When TS – Ta ≥ dTSH the heat pump provides heated
water to the space heang terminals and when Ta ≥ TS the heat pump does not
provide heated water to the space heang terminals. Refer to Figure 3-7.23. dTSH is
only relevant if YES is selected for ROOM TEMP in the TEMP. TYPE SETTING menu.
Refer to Part 3, 7.8 “TEMP. TYPE SETTING Menu”.
Figure 3-7.23: dTSH
Note:
Only when ROOM TEMP is enabled will this funcon
be available
t_INTERVAL_H sets the heang mode compressor re-start delay. When the compressor stops running, it will not re-start unl
at least t_INTERVAL_H minutes have elapsed.
7.7 AUTO MODE SETTING Menu
MENU > FOR SERVICEMAN > AUTO MODE SETTING
In AUTO MODE SETTING the following parameters should be set.
T4AUTOCMIN sets the ambient temperature below which the heat pump will not
provide chilled water for space cooling in auto mode. Refer to Figure 3-7.25.
T4AUTOHMAX sets the ambient temperature above which the heat pump will not
provide heated water for space heang in auto mode. Refer to Figure 3-7.25.
7.8 TEMP. TYPE SETTING Menu
MENU > FOR SERVICEMAN > TEMP. TYPE SETTING
For installaons without room thermostats, space heang and cooling modes can be
controlled in one of three dierent ways:
 according to the Mini Heat Pump Monobloc’s leaving water temperature
 alone; according to the room temperature detected by the Mini Heat Pump
Monobloc user interface’s built-in temperature sensor alone; or
 according to either the Mini Heat Pump Monobloc’s leaving water temperature or
the room temperature detected by the Mini Heat Pump Monobloc user interface’s
built-in temperature sensor.
Figure 3-7.26: TEMP. TYPE SETTING menu
WATER FLOW TEMP. sets whether space heang/cooling modes are controlled according to the Mini Heat Pump Monobloc’s
leaving water temperature. If YES is selected, the user is able to set the Mini Heat Pump Monobloc unit’s leaving water
temperature set temperature on the user interface’s main screen.
