Rear face
Most terminals are located on the rear face of the intelligent Touch Manager. However, they are covered with a terminal cover for safety
reasons. Removing 2 screws to detach this cover reveals various types of terminals as shown below.
<Rear face of intelligent Touch Manager>
A [POWER] The power line connection terminals. A power supply voltage of 100 to 240 VAC (at 50/60 Hz) is required. Near this terminal
block, there is a blue resin cable mount used for securing the power supply cables with cable ties.

equipment.
C [LINE, PHONE] The sockets used when subscribing to the DAIKIN “Air Conditioning Network Service System” online monitoring service
for air-conditioning systems. To use the “Air Conditioning Network Service System” service, you need to sign a separate maintenance
contact.
D [RESERVE] No Use.
E [RS-485] The terminals for connecting serial equipment.
F [plus ADP IF] The terminals for connecting one or more iTM plus adaptors when the intelligent Touch Manager is used to control
more air conditioning devices.
G [Di (1-4), COM] The terminals for connecting an external signal input device for stopping air conditioners in an emergency, or for
