Automating air conditioner operation with the timer function: how to set scheduled on and off times

Air Conditioner Timer Function: Purpose, Setup, and Operating Features

Purpose of the Timer Function

The “TIMER” button on the remote control allows you to set the air conditioner to turn on or off automatically after a specified time. This function enables you to predefine the time parameters for the unit’s activation or deactivation, providing automatic climate control in the room.

Timer function for scheduled air conditioner operation

Setting the On Timer (TIMER ON)

To set the automatic switch-on time for the air conditioner:

• With the unit off, press the “TIMER” button. The display will show “TIMER ON” and the current on-time setting.

• The time range is from 0.5 to 24 hours. Use the ^ and Ў buttons to set the desired time, in 0.5-hour increments up to 10 hours, then in 1-hour increments thereafter.

• Press the “TIMER” button again to activate the set time. The unit will turn on after the specified delay, using the saved operating parameters. Settings can be adjusted before the unit starts.

Setting the Off Timer (TIMER OFF)

To set the automatic switch-off time:

• With the unit on, press the “TIMER” button. The display will show “TIMER OFF” and the current off-time setting.

• The time range is also from 0.5 to 24 hours. Adjust the value using the ^ and Ў buttons, as with the on timer.

• Press the “TIMER” button again to activate the function. The unit will turn off after the set time has elapsed.

Additional Operating Instructions

• To cancel the timer function after setting, press the “TIMER” button again.

• When the timer is active, the remote control must remain in line-of-sight with the unit, as signal transmission is via infrared.

• In timer mode, the remote periodically sends a signal to the unit for synchronization. Any obstacles between the remote and the indoor unit may disrupt this and cause the function to fail.

• The maximum timer range is 24 hours. Once the set time elapses, the unit will perform the programmed action (on or off).

Example Timer Settings

On Timer (TIMER ON)

The TIMER ON function is useful for having the air conditioner start automatically, for example, before you arrive home.

Example: To start the unit at 6:00 AM:

1. Press TIMER until the TIMER ON indicator appears; the set time will be displayed and flash.
2. Use the TEMP/TIME buttons to set the time (6:00) on the display.
3. Wait half a second; the TIMER ON indicator will stop flashing, and the timer will be active.

Off Timer (TIMER OFF)

The TIMER OFF function is useful for automatically stopping the air conditioner at a set time, such as before sleeping.

Example: To stop the unit at 11:00 PM:

1. Press TIMER until the TIMER OFF indicator appears; the set time will be displayed and flash.
2. Use the TEMP/TIME buttons to set the time (23:00) on the display.
3. Wait half a second; the TIMER OFF indicator will stop flashing, and the timer will be active.

Combined Timer (TIMER OFF + TIMER ON)

Example: It is now 8:00 PM, and you want the unit to turn off at 11:00 PM and turn on again at 6:00 AM.

1. Press TIMER until TIMER OFF appears.
2. Use the TEMP/TIME buttons to set the time (23:00).
3. Press TIMER again until TIMER ON appears.
4. Set the time (6:00) using TEMP/TIME.
5. Wait half a second; the TIMER ON indicator will stop flashing, and the timer will be active.

Combined Timer (TIMER ON + TIMER OFF)

Example: It is now 8:00 PM, and you want the unit to turn on at 6:00 AM and turn off at 8:00 AM.

1. Press TIMER until TIMER ON appears.
2. Set the time (6:00).
3. Press TIMER again until TIMER OFF appears.
4. Set the time (8:00).
5. Wait half a second; the TIMER OFF indicator will stop flashing, and the timer will be active.

(!) Note: Setting a combined timer with only a 5-minute interval may not be processed correctly by the indoor unit’s processor. Use intervals of at least 15 minutes for reliable operation.
