are connected to the same outdoor units) to Cooling or Heating

by periodically monitoring the room temperature and the preset

temperature of each group and determining the best operation

mode.

The TC-24A described in this manual is a centralized controller with color LCD touch panel for air

conditioning units, LOSSNAY, and general equipment using the Mitsubishi Electric DIDO controller (PAC-

YG66DCA).

TC-24A can control up to 24 units/24 groups. (*1)

TC-24A controls and monitors the air conditioning units of each group. TC-24A also can control detailed

scheduling and prohibits the local remote controller operation in each room (group), which may lead to

energy savings.

Basic operations are accessed through the TC-24A touch panel. ON/OFF, Hold, and Set back operations

that control air conditioning units collectively are accessed by using buttons next to the touch panel.

TC-24A display screen consists of three types, corresponding to the usage.

HOME screen : Monitoring screen to monitor the operation status of the units

(described in this Instruction Book)

Main Menu screen : Setting screen to set the functions such as schedule settings

(described in this Instruction Book)

Maintenance screen : Initial setting screen to set the basic systems such as group settings

(described in Initial Setting Manual)

* 1 Group: minimum unit to be controlled by TC-24A

A group consists of units (16 units maximum).

Buttons ②,③, and ④have LED on the top.

TC-24A features a 5"-wide color LCD touch panel. Touch panel displays the operation status

of the units. Function settings such as week schedule settings are accessed through the touch

panel. The backlight lights up when the panel is touched, and lights off after certain period of

time. The backlight will remain lit as long as an error exists.

①Display/Touch panel

The Collective ON/OFF button enables the collective ON/OFF function that allows the user to

turn on/off the air conditioning units, LOSSNAY, and DIDO controllers in all groups collectively.

The LED corresponds to the operation status of controlled units.

Unlit : Indicates that all units are stopped.

Lit : Indicates that one or more units are in operation.

Blink : Indicates that an error is occurring.

②Collective ON/OFF Button *1

The Hold button enables the hold function that allows the user to retain the current operation

status for all selected groups collectively.

While the hold function is enabled, the scheduled operation is suspended, and the local remote

controller operation is also prohibited.

Unlit : Normal operation

Lit : HOLD-on

③HOLD Button *1, *2, *3

The Setback button enables the setback mode for all selected groups collectively. The setback

function automatically switches the system between cooling and heating to maintain the room

temperature within the set temperature range. The wider the set temperature range, the greater

the energy saving.

To keep the setback mode, enable the hold function.

Unlit : Normal operation mode

Lit : Setback mode

④SET BACK Button *1, *2, *3

The power indicator lights up when the power to TC-24A is turned on.

Unlit : Power OFF

Lit : Power ON

⑤Power indicator

Touch panel / Buttons

*1 When the button is pressed while the operation is prohibited, the LED will blink twice.
