Description
A backlight is used for the LCD of the intelligent Touch Controller. The backlight
has its service life and the luminance of the backlight is reduced in proportion to
the period of time it is illuminated. This setting is for preventing the luminance
from being reduced in a short time by automatically turning the backlight OFF
when the touch panel has been left untouched for a set period of time.
If the backlight has been turned off automatically, touching the panel illuminates
the backlight again.
Backlight setting includes the following two steps:
1.Set the time before the backlight is automatically turned OFF.
Range: 1 - 60 minutes in increments of one minute.
2.Set whether the backlight should be automatically illuminated when any error is
generated in the air conditioner while the backlight is turned OFF.
Enable/Disable
Note: If this setting is not made, the backlight generally requires replacement every 3
- 4 years.
The life of the backlight becomes even shorter if it is illuminated in a low
temperature (10°C or lower) environment for a long time.
When using the intelligent Touch Controller in a low temperature environment,
it is recommended that a shorter time is set for 1. above and Disabled for 2.
Backlight
Setup
Set the name, description, icons to be displayed and temperature setting limit
(see Note) for the group.
If this registration is not made, addresses for central management of the group is
used for the Name and Description. Operation is not affected if these settings
are not made.
Addresses for central management include up to 64 addresses 1-00, 1-01, ......
1-15, 2-00, ...... 4-15.
(Note): The temperature setting limit is a function to allow operation only within
the preset temperature limit to prevent too much cooling or heating.
(The limit function above does not work when the operation mode of the
air conditioners is Auto.)
Ex.: Temperature setting limit: 25 - 35°C cooling
If the temperature is set to 20°C with the remote control, the intelligent
Touch Controller automatically changes the temperature setting to 25°C.
Group Setup
Set the name, description, icons to be displayed and sequential starting of the
groups registered for a zone (see Note), and groups to be registered for the zone.
The zone includes “Collective,” for which all groups are registered in advance.
This zone is made available for making the settings for all of the air
conditioners connected to the intelligent Touch Controller. The name,
description or registered groups cannot be changed for this Collective zone.
(Note): Setting sequential starting of groups registered for the zone
When multiple groups are registered for a zone and operation is performed by
the zone, air conditioner outdoor units start operation at one time. If many
outdoor units start at the same time, a large amount of current is used
momentarily, which may trip the breaker when the power capacity of the
receiving device is not enough. This setting is a function to prevent such
phenomenon by starting air conditioners one by one.
(Memo 1): When power distribution (optional) is performed, the zone registered
here becomes the unit for distribution (tenant). Register the zone
setting by the tenant.
(Memo 2): One group can be registered for more than one zone.

Description
This function allows the optimal room temperature to be maintained without the users
having to change the operation mode by automatically switching the air conditioner’s
operation mode (cooling or heating) according to the room temperature for locations
where the temperature difference during the day and at night is very large.
< Overview of Function >
This function automatically switches the air conditioner’s operation mode and set
temperature in units of one (4) automatic cooling/heating switch group according
to the following 3 parameters: (1) main set temperature, (2) main room
temperature, and the difference between the set temperatures when in cooling and in
heating operation (listed hereafter as (3) temperature difference).
[1]
Control Method (How to determine the (1) Main Set Temperature and (2) Main Room Temperature)
The 3 following methods exist for determining the above temperatures.
1.Fixed Air Conditioner Method
The first indoor unit (the one highest on the screen) among those registered in the
automatic cooling/heating switch group is designated the main indoor unit and the set
temperature and room temperature of that indoor unit are designated the main set
temperature and main room temperature.
Note, however that if the main indoor unit is in fan operation mode, its automatic
cooling/heating switch group cannot be controlled.
2.Operating Air Conditioner Selection Method
Starting with the first indoor unit (the one highest on the screen) of those registered in
the automatic cooling/heating switch group and working down, a search is performed
to find an indoor unit which is both operating and in either cooling, heating, or
automatic operation mode. The first one which satisfies both of these conditions is
designated the main indoor unit and the set temperature and room temperature of that
indoor unit are designated the main set temperature and main room temperature.
If none is found which satisfies these conditions, the main set temperature and main
room temperature are determined using the Fixed Air Conditioner Method shown
above.
3.Average Method
All the indoor units which are registered in the automatic cooling/heating switch group,
are operating, and are either in cooling, heating, or automatic mode are found, and
the averages for their set temperatures and room temperatures are calculated and
used as the main set temperature and main room temperature. (Decimals are
rounded up.) Note, however, that if there no air conditioners among the registered air
conditioners for the averages to be calculated, the main set temperature and main
room temperature are determined using the Fixed Air Conditioner Method shown
above.
[2] (3) Temperature Difference
The temperature difference is the difference between the set temperatures when
automatically switching between cooling and heating when using this control.
The temperature difference is set to between 1°C and 7°C in 1°C units.
(When shipped from the factory, the setting is 2°C.)
[3] (4) Automatic Cooling/Heating Switch Group
• This control is performed using one automatic cooling/heating switch group as a unit.
•
Up to 64 indoor unit groups can be registered in one automatic cooling/heating switch group.
• It is not possible to register the same indoor unit to multiple automatic
cooling/heating switch groups.
• Up to 8 automatic cooling/heating switch groups can be registered in this unit.
• These controls can be enabled and disenabled for each individual automatic
cooling/heating switch group.
(These controls only work for groups set as enabled.)
• A mark indicating that the indoor unit is under automatic control will appear on the
monitor screen.

Settings
The control instruction is sent to the indoor units registered in the automatic
cooling/heating switch group when the control implementation conditions shown on
the previous page are satisfied. The actual control instructions sent differ according to
the control method setting (fixed air conditioner/operating air conditioner
selection/average) and the satisfied conditions (switch from cooling to heating, etc.).
The control instructions for each situation are shown below.
<Instructions sent to indoor units when control is implemented>
1.Fixed air conditioner/operating air conditioner selection methods
The control instructions are determined by the operation mode of the main indoor
unit and the main set temperature. Instructions regarding the operation mode and
the set temperature, shown below, are sent to all the indoor units registered in the
group once all the control implementation conditions on the previous page are
satisfied.
For this control, when the operation mode of the main indoor unit is automatic,
whether it is automatic cooling mode or automatic heating mode is checked when
judging the control conditions. Once the instructions have been determined, either a
cooling or a heating instruction is sent to indoor units in automatic operation mode.
(They switch from automatic to cooling or heating.)
2. Average Method
Unlike the fixed air conditioner and operating air conditioner selection methods, the
set temperature is decided based on considerations of the current set temperature
for each individual unit, without sending the same instruction based on the main
indoor unit to all the air conditioners. When implementing the control, the following
operation modes and set temperature instructions are executed.

<Precautions when using this control>
1.Do not use the set temperature restriction function in indoor units which are subject
to control.
If it is used, operation modes will be switched and the set temperature will be changed
repeatedly, possibly causing the air conditioners to break down.
(See P44 for how to set the set temperature restriction function.)
2.The following will happen if a communication error (the icon on the screen is blue)
occurs in the air conditioner being controlled.
2-1.Fixed air conditioner
If the main unit experiences a communication error, the automatic cooling/heating
switch group control will not happen.
2-2.Operating Air Conditioner Selection Method
Remove the air conditioner experiencing the communication error from selection
as the main unit, and select an air conditioner with normal communication.
2-3.Average Method
Remove the air conditioner experiencing the communication error from the
calculation for the average, and only use air conditioners with normal
communication for calculating the average.
3.Control which matches the main unit’s operation mode
(Control for when the operation mode of the main unit does not represent the
automatic cooling/heating switch group.)
It is possible that only the operation mode for the main unit is changed when control
using this function is done based on the main group unit (when the control method is
fixed air conditioner or operating air conditioner). The following control is performed
because it is possible that the operation mode of air conditioners other than the
main unit in the group might be in violation of the purpose of control and not
automatically switch if the conditions for implementing control using this function are
not satisfied.
[Example] Heating Mode-Matched Control
When the main unit is already operating in heating mode, whether or not the
conditions for implementing a switch from cooling to heating (main room temperature
< main set temperature – temperature difference) depends on the state
(environment) of the main unit. (If only the main unit is in heating operation, it is
possible that the room temperature might not rise because of the indoor units other
than the main unit which are in cooling operation, and the above control conditions
might not be satisfied.)
Therefore, only when control is performed based on the main group unit is the
control below performed depending on the operation mode of the main group unit.

4.Because this control automatically switches the operation mode, if the air
conditioner is not a cooling/heating free unit, always register indoor units which have
the right to select cooling or heating for the same cooling system to the same
automatic cooling/heating switch group, when controlling indoor units which do not
have such rights.
Unexpected things may happen if control is done using the following
incorrect automatic cooling/heating switch group settings.
If indoor units (address 1-02) which do not have the right to select cooling or heating
for the same cooling system are not registered to the same automatic cooling/heating
switch group, address 1-02 will behave in the following way.
[Actions related to operation mode]
If the room temperature of Group 1 rises, group 1 will switch to cooling as per this
control and the set temperature will become 25°C (if the temperature difference is
5°C).
When this happens, the set temperature of the indoor unit at 1-02 will continue at
23°C although only the operation mode will change to cooling, i.e. in a different
operation mode from the other indoor units in Group 2.
→The operation mode will be determined by Group 1.
[Actions regarding set temperature]
If the room temperature of Group 2 rises, group 2 will switch to cooling as per this
control and the set temperature will become 28°C (if the temperature difference is
5°C).
When this happens, the operation mode of the indoor unit at 1-02 will continue in
heating and only the set temperature will change to 28°C, i.e. in a different operation
mode from the other indoor units in Group 2.
→The set temperature will be determined by Group 2.

This function automatically starts and stops air conditioners in order to prevent the
room temperature of unmanned rooms from getting too high or too low. For example,
This has the following advantages.
• It prevents overheating of or condensation from forming on equipment which needs
to be temperature controlled in unmanned rooms.
• It can also help buildings and not just individual rooms to preserve heat by
preventing unmanned rooms from reaching extremes of temperature at night.
<Overview of Function>
This function performs automatic control by monitoring the relationship between the
set upper and lower limits and the room temperature (the air conditioner intake
temperature) to prevent the set room temperature from exceeding those limits. This
function starts and stops the air conditioners and changes the operation mode.
• Cooling operation control (and stop control)
Cooling operation is automatically started when the room temperature rises above the
set upper temperature limit.
The air conditioner is stopped once the room temperature falls sufficiently far below
the upper temperature limit (upper temperature limit – 4°C or more) during cooling due
to this control.
• Heating operation control (and stop control)
Heating operation is automatically started when the room temperature falls below the
set lower temperature limit.
The air conditioner is stopped once the room temperature rises sufficiently far above
the lower temperature limit (lower temperature limit + 4°C or more) during heating due
to this control.
q:Controlled air conditioners
• This controls auto-start and auto-stop for each air conditioner based on the
temperature set for each room temperature limit control group.
• This control is not applicable to air conditioners which are already operating,
even if they are registered to the room temperature limit control group. (It is only
applicable to stopped air conditioners.)
• Up to 64 indoor groups can be registered in one room temperature limit control
group.
• It is not possible to register the same indoor unit to multiple room temperature
limit control groups.
• Up to 8 room temperature limit control groups can be registered in this unit.
• These controls can be enabled and disenabled for each individual room
temperature limit control group.
(These controls only work for groups set as enabled.)
• A mark indicating that the indoor unit is under automatic control will appear on
the monitor screen.
w:Upper room temperature limit
• Upper and lower room temperature limit
The upper and lower room temperature limits desired for automatic control. The
settable range of upper and lower limits is as follows.
Upper limit : 34°C to 50°C in 1°C units. (The default is 36°C.)
Lower limit : 2°C to 14°C in 1°C units. (The default is 14°C.)
The temperature different between the upper or lower limit and the room temperature
when the air conditioner under cooling (heating) operation control using this function
(to prevent hunting) is 4°C.

e:Control Implementation Conditions
The relationship between room temperature, upper/lower limit, and operation
mode is shown below.
The controls are implemented when the control conditions are satisfied, every 5
minutes from the time the power is turned on.
This function performs stop control for cooling/heating operation and other
operation controls to prevent excessive increase or decrease of the room
temperature. The set values of room temperature upper/lower limit control group
are used for the upper/lower limit values and other factors of this control.
This control is not performed for the group of air conditioners to which this control
is set invalid. The set temperatures of the air conditioners are not changed by
this control.
qStart condition of cooling operation:
Cooling operation is controlled when the room temperature is higher than the
upper limit of room temperature and the unit is stopped.
wStart condition of heating operation:
Heating operation is controlled when the room temperature is lower than the
lower limit of room temperature and the unit is stopped.
eStop condition:
The air conditioners under cooling/heating control by this function stop when
any of the following conditions are met.
• During cooling operation
“Room temperature is lower than the upper limit of room temperature – 4°C”
or “Room temperature is lower than the cooling set temperature”
• During heating operation
“Room temperature is higher than the lower limit of room temperature + 4°C”
or “Room temperature is higher than the heating set temperature”
