T4AUTOCMIN is the minimum operating ambient temperature for
cooling in auto mode. The unit will turn off if ambient temperature
lower than it when in space cooling operation.
T4AUTOHMAX is the maximum operating ambient temperature for
heating in auto mode. The unit will turn off if ambient temperature
higher than it when in space heating operation.

temperature described in the picture below

6.12 TEMP. TYPE SETTING
■ About TEMP. TYPE SETTING
The TEMP. TYPE SETTING is used for selecting whether the water
flow temperature or room temperature to control the heat pump's
ON/OFF.
When ROOM TEMP. is enabled, the target outlet water temperature
will be calculated from climate related curves.
■ How to enter the TEMP. TYPE SETTING
To enter the TEMP.TYPE SETTING, go to MENU> FOR
SERVICEMAN> TEMP. TYPE SETTING. Press OK. The following
page will appear:

ROOM TEMP.
SCROLL
If you set WATER FLOW TEMP. to YES, and set ROOM TEMP. to
NON, then the water flow temperature will display on the home page,
and the water flow temperature will work as the target temperature.

If you set WATER FLOW TEMP. to YES, and set ROOM TEMP. to
YES, then the water temperature will be displayed on the home page,
them both water temperature and room temperature will be detected,
either the water temperature or the room temperature reaches the
target temperature will the unit turn off.
In this condition，the first target outlet water temperature can be
set in the main page, the second one can be calculated from the
climate related curves, in heat mode, the higher one will be the real
target outlet temperature, while in cool mode, the lower one will be
selected.

6.13 ROOM THERMOSTAT
■ About ROOM THERMOSTAT
The ROOM THERMOSTAT is used to set whether the room
thermostat is available.
■ How to set the ROOM THERMOSTAT
To set the ROOM THERMOSTAT, go to MENU> FOR
SERVICEMAN> ROOM THERMOSTAT. Press OK. The following
page will appear:

ROOM THERMOSTAT
MODE SETTING
DUAL ROOM
THERMOSTAT
SCROLL
If room thermostat is available, please select YES and press OK.
In MODE SETTING, if YES is selected, the mode setting and on/off
of the unit can't be done by the user interface, the timer function is
unavailable; the running mode, on/off of the unit decided by the room
thermostat, while the temperature setting can be done by the user
interface. If NON is selected, the user interface can be used to set
operation mode and target temperature, while the on/off of the unit is
determined by room thermostat, the timer function is unavailable.
In DUAL ROOM THERMOSTAT, if YES is selected, the ROOM
THERMOSTAT、MODE SETTING will turn to NON automatically,
and the WATER FLOW TEMP. and ROOM TEMP. forcibly set to
YES. The timer function in the user interface is unavailable; the
setting of operation mode and target temperature can be done on the
user interface.
The "DUAL ROOM THERMOSTA" function can be used only when
application 6(refer to "Application 6") is applied. If zone A requires
heating/cooling (ON signal from room thermostat 5A), the unit will
turn on, the operation mode and target temperature of outlet water
should be set in the user interface. If zone B requires heating/cooling
(ON signal from room thermostat 5B), the unit will turn on, the
operation mode can be set in the user interface, the target
temperature of outlet water will be decided by ambient temperature
(target outlet water temperature is calculated from climate related
curves, if no curves selected, the default curve will be curve 4). If no
heating/cooling demanded for both zone A and zone B (OFF signal
from thermostat 5A and 5heat by heat pump onlyB), the unit will turn
off.
NOTE：The setting in the user interface should correspond to the
wiring of thermostat. If YES is selected in ROOM THERMOSTAT
and the MODE SETTING is NON, the wiring of thermostat should
follow method A. If the MODE SETTING is YES, then the wiring
should follow method B If "DUAL ROOM THERMOSTAT" is selected,
the wiring of room thermostat should follow "method C" . (refer to
"Connection for other components/For room thermostat")
6.14 OTHER HEATING SOURCE
■ About OTHER HEATING SOURCE
The OTHER HEATING SOURCE is used to set whether the backup
heater、additional heating source like boiler、solar energy kit is
available.
