which the heat pump provides heated water to the space heating terminals. When TS – Ta ≥ dTSH the heat pump provides
heated water to the space heating terminals and when Ta ≥ TS the heat pump does not provide heated water to the space
heating terminals. Refer to Figure 3-7.16. 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”.
t_INTERVAL_H sets the heating mode compressor re-start delay. When the compressor stops running, it will not re-start
until at least t_INTERVAL_H minutes have elapsed.
T1SetH1 sets the temperature 1 of automatic setting curve for heating mode.
T1SetH2 sets the temperature 2 of automatic setting curve for heating mode.
T4H1 sets the ambient temperature 1 of automatic setting curve for heating mode.
T4H2 sets the ambient temperature 2 of automatic setting curve for heating mode.
ZONE1 H-EMISSION sets the emission type for heating mode.
ZONE2 H-EMISSION sets the emission type for heating mode.
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 3-7.18.
T4AUTOHMAX sets the ambient temperature above which the heat pump will
not provide heated water for space heating in auto mode. Refer to Figure 3-7.18.

Abreviations:
HP: Heat pump
AHS: Additional heating source
IBH: Backup electric heater
T4CMAX: The ambient temperature above which the heat pump will not operate in cooling
mode.
