Daikin BRC073A1

Answers and step-by-step fixes from the official Daikin manual.

What does the display or lamp show?

• Error icon + operation lamp blinking: The unit has an error. The error icon on the screen and the green operation lamp blink together to show a fault.
• Mode Conflict: Mode conflict between indoor units. On a multi system, this appears when several indoor units are told to run in different modes at once. The operation lamp flashes and the units without priority enter standby.
• Timer problem icon: Clock needs to be set again. This icon means the schedule timer will not run until the clock is reset.
• Buttons have been locked.: Key lock is on. All buttons are disabled while the key lock is active, and this message appears if a button is pressed.
• Setback icon flashing: Setback has turned the unit on. The setback icon flashes when the unit was started automatically by the setback function to keep the room within a set range.
• Under Centralised control icon: Central control is managing the unit. This icon shows the unit is under central control equipment, so it cannot be operated from this remote controller.

Common problems

The error icon and lamp are blinking

1. Is the Menu/Enter button enabled? You need the Menu/Enter button enabled to view the error code.

3. Write down the code and model, then call your dealer Give your Daikin dealer the error code and model name.

The screen shows Mode Conflict

1. Are several indoor units connected to one outdoor unit? Mode conflict only happens on multi systems with more than one indoor unit on an outdoor unit.
2. Is a Priority Room set? If a Priority Room setting is active, that unit's mode wins and the others go to standby.
3. If no Priority Room, which unit turned on first? Without a Priority Room, the unit turned on first sets the mode and later units stand by.
4. Set the other units to match Switch the units without priority to the same mode, or to Auto, so they run together.

The wireless remote and the wired controller show different settings

1. Are you using both a wired and wireless remote at the same time? Using both together can make settings on one not match the other.
2. Did a change made on the wired controller not reach the wireless one? Press the wireless ON/OFF button twice to catch it up to the real unit status.
3. Are two different weekly schedules programmed? Use only the wired controller's schedule timer, and delete any schedule set on the wireless remote.

The schedule isn't turning the unit on or off

1. Has the clock been set? The schedule only runs once the date and time have been set.
2. Is the Timer problem icon showing? This icon means the clock needs to be set again, and the schedule won't run until it is.
3. Is the schedule turned on? Open the Schedule menu and set Enable/Disable to Enable.
