Wall-Mounted Remote Control Wiring
WARNING
•
The wiring should adapt to the wire control current.
Otherwise, electric leakage or overheating may occur
and result in fire.
• The specified cables shall be used in the wiring. No
external force may be applied to the terminal.
Otherwise, the wire may be damaged and heating
may occur and result in fire.
CAUTION
• The shielded wire must be grounded.
•
The connecting cable should not be longer than 20m (65.5’).
• The remote control operates on a low voltage circuit
loops. DO NOT connect a 220V or 380V cable to the
circuit loop.
• Make sure that configured tubes are 30-50cm
(12-20”) or more apart.
•
DO NOT employ an ohmmeter to detect the
insulation after wiring the remote control.

If there is a connection lug at the end of
shielded wire, the connection lug should be
properly grounded.

No Name Quantity Remarks
1 Remote Control 1
2 Screws 3 M4X20 (For mounting on the wall)
3 Anchors 3 For mounting on the wall
4Screws 2 M4X25 (For mounting on switch box)
5 Plastic screw bars 2 For fixing on switch box
6The connective
wires group 1 Optional
2. Prepare the following tools

2Wiring tube (insulating sleeve and tightening screw) 1
3. Select installation location
DO NOT install the remote control near ammable
liquids or gases such as gasoline or hydrogen sulde.
Doing so creates a re hazard.

Installation Method
1. Remove the top panel of remote control
Insert a screwdriver into the two slots at the bottom
of the remote control to pop o the top panel.

3. Set the time and date
The remote control has a small, built-in battery that
allows the time and date to be set. That way the
remote control can keep time even during a power
outage. When the unit displays an incorrect time and
date the batteries need to be replaced.
4. Reattach the top panel of the remote control
Fig. 11
CAUTION
DO NOT clamp the wires when reattaching the top
panel.

Constant air volume testing
• You can use the unit’s automatic airow adjustment
function to set external static pressure.
• Automatic airow adjustment is the volume of blow-off
air that has been automatically adjusted to the quantity
rated.
1. Make sure the test run is done with a dry coil. If the
coil is not dry, run the unit for 2 hours in FAN ONLY mode
to dry the coil.
2. Check that both power supply wiring and duct
installation have been completed. Check that any closing
dampers are open. Check that the air lter is properly
attached to the air suction side passage of the unit.
3. Set the parameters for automatic airow adjustment.
When the air conditioning unit is o, perform the
follwoing steps:
(To set external static pressure) (some models)

14
①When the unit is turned o, hold the MODE button
and FAN button down together for three seconds.
("AF" indicator ashes for 3 times.)
②Press “△” or “▽” to select the AF.
③Press “MODE”. The air conditioning unit
will then start the fan for airow automatic
adjustment.
After 6 minutes, the air conditioning
unit stops operating once automatic
airow adjustment has nished.
CAUTION
• DO NOT adjust the dampers when automatic
airow adjustment is active.

(some models)
When the air conditioning unit is o, perform the
follwoing steps:
①Press“MODE” and "FAN" for three seconds.
②Press “△” or “▽” to select the SP.
③Press “MODE” to set the airow rate in the range
of 0~4.
④Press “ON/OFF”to nish the airow setting.
“0”: No airow change
