Notes
(1) Some functions cannot be used depending on the indoor model used.
(2) The receiving side power supply is DC 12 V (10 mA).
(3) If the energy consumption calculation function is necessary, use the SLB-3-ER.
(4) The lifetime of the keying of touch panel is one million times.
The lifetime of LCD is about 20,000 hours. depending also upon the backlight OFF time setting. (The brightness will become half of the starting value.)
(5) The touch panel has an endurance of approximately 1 million times.
(6) In the environment setting screen, it is also possible to change the batch error output setting as open for normal and closed for error.
(7) The air conditioning charges calculations of this unit are not based on OIML, the international standard.
(8) • The center console SLA-2A series can be connected 1 unit per system.
• It cannot be combined with the center console SLA-1 series, SLA-200 series and the CHC-M series, SC-WGW-A series, SC-BGW-A series or SC-LIF
series,
SC-LGW-A series.
• Multiple SLA-3-ER and SLB-3-ER units cannot be connected on the same network.
(9) SLB-3-ER cost calculation results cannot be guaranteed.

(a) In case of installing on the control board
1) Please use the control board of the size of 300mm ⳯ 400mm ⳯ 120mm or larger.
2) Please be sure to lock the control board to protect persons from the electric shock.
3) Please do not use any heat insulation material on the control board.
4) If you use it, accumulated heat will cause the center console to malfunction.
(b) In case of embedding in a wall
Please be sure to use the special box, SLA3R-BX (sold separately) to secure sufficient air circulation space. If the box is
unused, the center console will not work properly because of heat buildup inside the box. Please be sure to use for protecting
persons from the electric shock.Please check that the sufficient space is available in the wall.
When the inside of the wall is divided and have a cavity, please create space more than 0.08m
3
. Refer to the next page.
If there is no partition on the left, right, top and bottom of the center console, please create a space that is 105mm ordeeper.
When you cannot create the sufficient space or thickness of the wall is above 15mm, please install the center console on the
control board.
Before the installation, shut off the power supply to avoid an electric shock.
Please locate or protect so that the unit will not be forced against wiring.
(1) Installation place
Install this unit indoors without the influence of the electromagnetic wave, or splashing such as water and dust.
Necessary clearance is 200mm or more beneath the center console and 500mm or more in front of the center console.

(3) Installation method
(a) Embed signal wire and power supply wire in a wall beforehand.
(b) Connect wires to the terminal block.
(c) Confirm power supply voltage and connect correctly.
(d) Remove the upper case
1) Take out two screws using a cross slot screwdriver. (Don't lose the screws)
2) Pull the upper case a little forward and push above. Then, upper case can be removed.
M4 screws, 4 pieces
(accessory of the unit)
Fix the unit to the SLA3R-BX with the M4 screws. (4 places)
Wire separately the power supply wire and the signal wire for
preventing malfunctions.
Please do not install other units on the same
control board that will cause temperature rise.
Please do not
install facing
upward or in
slanted position.
Please do not install multiple controllers on the
same control board. They can cause the temperature
rise of the control board interior and the center
consoles will not work properly.
When there is no choice but to install the multiple
controllers,please adjust the tempereture inside the
control board 40 degrees or less. (for example
cooling fan installation)
