Other than the supplied outdoor temperature sensor, it is also possible
to connect other brand multi-purpose sensors to the device.
This section describes the wiring when connecting the multi-purpose sensors.
(If you are not using the multi-purpose sensors, do not perform the wiring connection
to connector X2A.)
Use sensors with an output of DC 0 ~ 5V. Wire as shown in the diagram.
(The sensors and extension wiring should be procured locally.)
An extension harness is required as the included harness is only
10cm long.
Pressure tools are needed when extending the harness.
When connecting multi-purpose sensors, it will be necessary to
cut the jumper line in the printed board assembly in the
device and change the dipswitch settings. (See
and in 2 - 5 for settings.)

Securing the sensor
Always secure the sensor downwards as shown in the diagram. Install in a well-ventilated location
where the unit will not be subject to direct rain or sunlight. (If the unit receives direct sunlight, it
might detect a temperature higher than the actual temperature.)
