How to Install

1. Determine the installation of the remote sensor (switch box). The following items must be observed.
2. Select a place where the remote sensor will detect an average temperature of the room, and where the sensor will not be subject to direct sunlight, heat sources, or the blow-off from the air conditioner, etc.
3. Install the sensor within the length of the cable provided (12m). (The cable cannot be extended. If extended, it may cause misoperation due to noise.)
4. The following parts must be procured at the site.

  * Cross-recessed pan head screw M4 …. Tow screws
  * Single switch box
  * Thin steel conduit
  * Lock nut, bushing

2. Connect the wires.
   • Connect the 2-core cable to the terminal block in the lowercase. Peel the sheath of the 2-core cable as shown in Fig.1 , and correctly wire it as shown in Fig.2.
   • The wiring connection of the indoor unit’s electrical box and remote sensor is shown in Fig.3. There are three methods of connecting the 2-core cable to the electrical box.
   • Exchange 2-core cable (connector 20)
   1. When using the connector attached to the end of the 2-core cable as it is.
   2. When cutting the connector attached to the end of the 2-core cable and connecting the cable to the terminal block in the I.B. (Indoor Board).
   3. When using the enclosed post for connection and convert cable.
   • The above three methods are used according to the indoor unit being used. If the 2-core cable is to be embedded in the wall, follow Fig.4.
3. Install the lowercase on the wall or switch box.
   • NOTE The recommended tightening torque for installing the 2-core cable to the terminal block is 1.17N·m.
   • CAUTION:
   • If the screws are tightened too hard, the case may break or deform.
   • Install the sensor on a flat wall. If installed on a bumpy wall, the case may break or trouble may occur.
4. Fit the upper case.
   • Catch the two upper claws first, and fit the case as shown on the left.
   • CAUTION Securely fit the case until a catching sound is heard. It may drop off if is not fitted securely.
   • To remove the case, fit a flat-flap screwdriver into the claw section as shown below, and move the screwdriver in the direction of the arrow.
   • CAUTION Do not turn the screwdriver when it is fit into the claw section as the claws may be broken.
5. Wiring hole for direction installation on wall, etc. Cut the thin section (shaded section) of the lower case with a knife or pair of nippers, etc. The 2-core cable connected to the terminal block is led out from here.
6. Securely seal the wiring lead hole with putty or silicon to prevent dew, water drops, cockroaches, and other insects from entering.
   • When installing directly on the wall, seal the section cut on the lower case with putty or silicon.
   • If the wiring is to be passed through a hole in the wall (when leading the wiring from the rear of the remote sensor), seal the hole in the same manner.
   • When installing on a switch box, seal the connection of the switch box and conduit with putty or silicon.
   • To lead wiring from the top of a remote sensor.
   • To lead wiring from the rear of a remote sensor.
