About TEMP. TYPE SETTING
TEMP. TYPE SETTING
About OTHER HEATING SOURCE
Other HEATING SOURCE
The OTHER HEATING SOURCE is used to set whether the backup
heater, and additional heating sources like a boiler or solar energy
kit is available.
If you set WATER FLOW TEMP. to YES, and set ROOM TEMP. to
NON, the water flow temperature will be displayed on the home page,
and the water flow temperature will work as the target temperature.
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 B. If the MODE SETTING is YES, then the wiring
should follow method A, If “DUAL ROOM THERMOSTAT” is selected,
the wiring of room thermostat should follow “method C” . (refer to
“9.6.6 Connection for other components/For room thermostat”)
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 is displayed:
Use ◄ ► and ▼ ▲ to scroll and adjust the parameter.
T4AUTOCMIN is the minimum operating ambient temperature for
cooling in auto mode. The unit will turn off if the ambient temperature
is lower when in space cooling operation.
T4AUTOHMAX is the maximum operating ambient temperature for
heating in auto mode. The unit will turn off if the ambient temperature
is higher when in space heating operation.
The relationship between heat pump operation and ambient
temperature is described in the picture below
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.
Both water temperature and room temperature will be detected and
when either the water temperature or the room temperature reaches
the target temperature the unit will turn off.
If you set WATER FLOW TEMP. to NON, and set ROOM TEMP.
to YES, then the room temperature will be displayed on the home
page, and the room temperature will work as the target temperature.
The target outlet water temperature can be calculated from the climate
related curves.
If ►is pressed, the main page will display the room temperature:

About ROOM THERMOSTAT
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 is displayed:
In this state, 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.
If the room thermostat is available, select YES and press OK. In
MODE SETTING, if YES is selected, the mode setting and the on/off
function cannot be performed from the user interface. The timer
function is unavailable; the operation mode, and the on/off function is
decided by the room thermostat. 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
function 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. is
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 THERMOSTAT” function can be used only when
application 6 (refer to
8.6 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 are
selected, the default curve will be curve 4). If no heating/cooling is
required for both zone A and zone B (OFF signal from thermostat 5A
and 5B), the unit will turn off.
In the picture, AHS is an additional heating source. IBH is a backup
heater in the unit.

The TEMP. TYPE SETTING is used for selecting whether the water
flow temperature or room temperature(detected by the temperature
sensor attached in the user interface) is used to control the ON/OFF
of the heat pump.
When ROOM TEMP. is enabled, the target outlet water temperature
will be calculated from climate-related curves(refer to “
10.1
Climate related curves
”).
