Commissioning notes
1. Initialise the AC Unit with Fujitsu AC Wall Controller connected to set the
required eld settings. Then disconnect the AC wall controller if it’s not to be used.
2. Wire AirTouch, gateway and AC indoor as per diagram and leave the dipswitches
on the gateway at their default position. Make sure all wires are connected
properly. If the gateway address is not 1, follow the Gateway Address Setting
table to set dipswitch S1
3. In the case the gateway is master and Fujitsu wall controller is connected as slave
(sub) or not connected: If AirTouch sensors are used for AC temperature control:
Settings on the AC wall controller: Have the Fujitsu wall controller connected as
Master and set thermostat sensor to the remote controller (Go to
Service->Function Setting, nd Function No 42, and set its value to 01.
Then go to Submenu and change “R. C. sensor control” from O to On).
Then set the wall controller back to Slave (sub) or remove it if it’s not to be used.
Settings on the Gateway: Set position 4 of S2 to ON (1) (Default)
Settings on the AirTouch screen: Go to AC Setup in the Installer settings and
select the proper temperature sensor for AC control.
Restart the AC and gateway rst and then power up AirTouch or power them
up at the same time.
If AirTouch sensors are not used and the Fujitsu wall controller is not connected,
the AC control sensor has to be set to AC return air sensor. The AirTouch screen
will show AirTouch sensors’ temperature as Home Temp or Control Sensor value.
4. In the case the gateway is connected as Slave and Fujitsu wall controller is con-
nected as Master. If AirTouch sensors are used for AC temperature control:
Settings on the AC wall controller: Set thermostat sensor to the remote controller
(Go to Service->Function Setting, nd Function No 42, and set its value to 01.
Then go to Submenu and change “R. C. sensor control” from O to On).
Settings on the Gateway: Set position 4 of S2 to O (0)
Settings on the AirTouch screen: Go to AC Setup in the Installer settings and
select the proper temperature sensor for AC control.
Restart the AC and gateway rst and then power up AirTouch or power them
up at the same time.
If AirTouch sensors are not used for AC temperature control and the AC is set to
use its return air sensor as control sensor, the AirTouch screen will show AirTouch
sensors’ temperature as Home Temp or Control Sensor value.
