Daikin BRC1D52 Remote Controller Details
The Daikin BRC1D52 is the wired remote controller of a VRV-system air conditioner. It can also control a Daikin Total Heat Exchanger HRV (Heat Reclaim Ventilation) unit. In a combined operation system, one controller starts and stops both the indoor air conditioner and the linked HRV unit. You do not need a separate ventilation controller for daily use. The HRV operation manual tells users to read the controller's own manual for full instructions.
Each press of the operation mode selector moves the display to the next mode. The modes available depend on how the system is installed. If the air conditioner and the HRV unit are not connected by a duct, the user can choose Cooling/Ventilation, Fan/Ventilation, or pure VENTILATION mode. In VENTILATION mode, the HRV runs on its own without the air conditioner. To do this, select the zone where you only want ventilation, then choose VENTILATION with the mode selector.
If the VRV indoor unit and the HRV are connected by a direct duct, the BRC1D52 cannot select VENTILATION mode. To run the HRV without cooling or heating, set the air conditioner to FAN VENTILATION mode and choose the low fan speed. This prevents unconditioned air from being forced through the indoor unit at high airflow.
The controller has a ventilation mode button. It switches the HRV between Automatic, Heat Exchange and Bypass ventilation. In Automatic mode, the unit's temperature sensor chooses between Bypass and Heat Exchange. In Heat Exchange mode, air passes through the element for total heat exchange. In Bypass mode, air goes around the element. A separate air flow rate changeover button selects the ventilation volume. It works alongside the air conditioner fan speed button.
The display has a defrost/hotstart icon and a centralized control indication. When a centralized controller manages the system, the centralized control indication appears on the display. While it is shown, ON/OFF and timer operation may be locked at the local controller. Other functions can still be adjusted. The operation lamp shows when the system is running.
The BRC1D52 handles maintenance reminders with an air filter cleaning time icon and an element cleaning time icon. A "FILTER" message tells the user to clean the HRV filter. After cleaning, press the dedicated reset button to clear the icon. Daikin says only a qualified service person should do maintenance, with the operation switch off and the power disconnected.
The inspection button is reserved for service technicians and is not meant for normal use. The controller also has timer buttons, which work the same way as on the dedicated HRV controller. Use the schedule timer button to turn the timer on or off. Use the time adjust button to set the time. Press the programming button to confirm the reservation.
If the system develops a fault, the controller displays a malfunction code. The codes cover several faults. They include thermistor faults (64, 65) and damper problems (6A). They also cover a locked rotor (A6), a fan communication error (C1), and transmission errors (U5, U8, UE). A wrong remote controller installation shows UA, and a repeated central address shows UC. For any of these codes, contact the dealer who sold you the unit. Some faults let the unit keep running, but it should still be inspected soon.
