Installing a Universal Comm. Kit
Installing IN/OUT sensor
1. Attach the EVA IN sensor after the distributor and on the lowest temperature pipe of a heat exchanger.
2. Install the EVA OUT sensor 200 mm (7.87") after the header of Indoor unit heat exchanger as shown in
the picture.
3. Insulate the EVA IN and OUT sensor so that it is not affected by airflow.
4. Install the ROOM temperature sensor on the RA (Return Air) path of Indoor unit.
※ In case of DOAS, install ROOM temperature sensor and enthalpy sensor (optional) on the OA (Outdoor Air)
path in front of indoor unit heat exchanger

Location of room temperature sensor
• In principle, the sensor holder of EVA IN/OUT sensor should be welded at the designated place and
then the EVA IN/OUT sensor should be fixed with a clip.
NOTE
• EVA IN/OUT sensor should be installed at the place where temperature of the heat exchanger inlet
or outlet can be measured accurately.
