Getting your HVAC system up and running with a Daikin BRC1C51/61 remote controller doesn't have to be a headache. Whether you’re a DIY enthusiast or just want to understand what your technician is doing, this guide breaks down the essential steps found in the installation manual. Before You Start: Safety First
Before touching any wires, ensure the power to the indoor unit is completely switched off. Working with HVAC electrics requires caution, so if you feel unsure, always call in a professional. 1. Choosing the Right Spot
Location is everything. For the most accurate temperature readings:
Avoid Direct Sunlight: Don't mount the controller where the sun hits it.
Stay Away from Drafts: Keep it clear of windows, doors, or direct air discharge from the vents.
Height Matters: Aim for about 1.5 meters (5 feet) above the floor. 2. Wiring the Controller
The BRC1C51 and 61 models use a simple two-wire, non-polar system. This is great news because it means you don't have to worry about which wire goes to which terminal (P1 and P2). Use a 2-core sheathed vinyl cord or cable ( mm2m m squared
Run the wire from the indoor unit's terminal block to the back of the remote controller.
Pro Tip: Keep the remote control wiring at least 50mm away from power lines to avoid electrical interference. 3. Mounting the Plate
The controller comes with a mounting plate. Secure this to the wall or an electrical box using the provided screws. Once the plate is level and the wires are pulled through the center hole, click the main body of the controller into place. 4. Field Settings (The Important Part)
Once powered on, you may need to configure "Field Settings" to tell the unit how to behave. This is done by holding the Inspection/Test button for 4 seconds. Mode No. 10: Used for setting things like filter signs.
Mode No. 12: Used to define the "Cool/Heat Selection" master if you have multiple units. 5. The Test Run
Don't just walk away! Perform a test run by pressing the Inspection/Test button twice. The unit will run for a short period to confirm the fan, cooling, and heating cycles are functioning correctly.

The Daikin BRC1C51/61 is a wired remote controller used to manage split-system and ducted air conditioning units. Installing it involves mounting a lower case, routing control wiring to the indoor unit, and snapping the upper case into place. 1. Choosing the Installation Site
Surface: Select a flat wall surface to avoid deforming the controller's lower case when tightening screws. daikin brc1c51 61 installation manual
Environment: Avoid areas exposed to direct sunlight, moisture, or heat sources.
Interference: Keep the controller and its wiring at least 3.3 to 3.5 feet (1 meter) away from televisions and radios to prevent electrical noise. 2. Mounting the Lower Case
Open the Controller: Use a screwdriver to lightly twist and release the tabs at the bottom to remove the upper case.
Prepare Wiring Entry: Cut out the plastic at the notched areas (top center, right, or bottom) for the wiring to enter the case.
Fix to Wall: Route the wire through the chosen hole and secure the lower case to the wall using the provided wood screws or small screws. 3. Wiring and Final Assembly
Connection: Connect the control wire to the CN_WIR connector on the printed circuit board (PCB) located on the upper case.
Indoor Unit Link: Connect the other end of the wire to the indoor unit's PCB, typically at the CN_NS connector for compatible models like the FTK/FTX series.
Snap On: Align the upper case with the four tabs on the lower case and press firmly until it clicks into place. Finish: Peel off the protective sheet from the display. 4. Initial Setup
Clock: To set the time, hold the timer button for 5 seconds until the display blinks. Use the arrow buttons to adjust the minutes and day of the week, then confirm.
Test Run: Turn on the main power. The system should take about 15–20 seconds to power up, after which you can test basic ON/OFF and mode functions. Operating Manual | Daikin Comfort
The Daikin BRC1C51/61 is a wired remote controller used to manage Daikin split systems and heat reclaim ventilation (HRV) units. Proper installation is critical to ensure safety, system performance, and a full range of functionality. Pre-Installation Safety Check
Before starting, observe these mandatory safety precautions:
Power Off: Shut off all power supplies to the indoor and outdoor units to prevent electric shock.
Qualified Personnel Only: Complex wiring and internal settings should be handled by a qualified technician.
Environmental Constraints: Do not install the controller in areas with high moisture, direct sunlight, or near heat sources. Getting your HVAC system up and running with
Avoid Noise Interference: Install control wires at least 3.5 feet (1 meter) away from televisions or radios to prevent electrical noise interference. Installation Procedures
The installation involves mounting the controller and connecting it to the indoor unit's control board. 1. Mounting the Controller
Open the Case: Insert a flathead screwdriver into the recesses at the bottom of the lower case to gently pry off the upper case. Be careful not to damage the internal printed circuit board (PCB).
Prepare Wiring Access: Cut the plastic at the notched area on the casing to create an entry point for the wires.
Secure the Back Plate: Mount the lower case (back plate) to a flat wall or pillar using the provided screws. Avoid over-tightening, as this can deform the plate and prevent the upper case from snapping on correctly.
Seal Entry Holes: Use putty or a similar sealant to close the wiring lead-in hole to prevent water, dust, or insects from entering. 2. Wiring and Connections
Terminal Connections: Connect the two-core remote controller wire to terminals P1 and P2 on the controller's PCB. These terminals are not polarity sensitive, meaning the wires can be connected in either position.
Indoor Unit Connection: Route the other end of the wire to the indoor unit and connect it to the corresponding P1 and P2 terminals on the unit's control board.
Group Control: If controlling multiple units, the remote is connected to the first unit, and subsequent units are daisy-chained via their P1/P2 terminals. Initial Setup and Configuration
Once the hardware is installed and power is restored, the controller must be configured for its specific application. Real-Time Clock (RTC) Setting To set the current time and day:
Press the RTC key once to enter setting mode (the day will blink). Use the UP/DOWN buttons to select the day. Press RTC to confirm and move to the hour setting. Adjust the hours and minutes using the same method.
The setting is confirmed only after all steps are completed; otherwise, it will exit after 5 seconds of inactivity. Field Settings and Hardware Jumpers
Jumpers: Technicians may need to adjust physical jumpers on the PCB to set temperature ranges (e.g., limiting the range to 20°C–30°C) or activate room temperature displays.
Sub-Controller Setup: If two remote controllers are used for one unit, one must be designated as the "Sub RC." Hold the Mode button for 4 seconds or longer until the display changes from "Main RC" to "Sub RC". Troubleshooting Common Issues
