Instruction Manual
RWV09 Central Controller
- Please read this operation manual before using the central controller.
- Please keep this manual carefully and safely.
- The illustration is for reference only, and the word description shall prevail.
This central controller can control VRF indoor units and Heat Recovery Vent (HRV). A maximum of 64 indoor units of any combination can be controlled to a single central controller.The central controller RWV09 can automatically recognize the model as a VRF system , no need to manually set up.
- When connected to a VRF system, each outdoor requires a ADV05 gateway (Flow Logic 3 outdoor unit can directly connect with this central controller).
Function introduction of central controller
-
For VRF system, three kinds of controlling mode: Last in first out, Central & Lock can be selected for indoor units.
Last in first out: the indoor unit will execute the last order send by central controller, wired controller or remote controller. For example, if firstly sending low fan speed order by central controller and then sending high speed fan order by wired controller, the indoor unit will execute high fan speed.
Central: central controller enjoys all functions while wired &remote controller can only control ON/OFF of indoor units.
Lock: central controller enjoys all functions while wired & remote controller cannot control indoor units. -
Receiving outer signal input: when receiving outer fire alarm signal, central controller will turn all indoor units off. Note: if no outer signal input, should short circuit the ALARM1 and ALARM2.
-
Weekly timer setting. Weekly timer for one or some or all units can be set and can run in cycle, or set Except Date and ONCE. the “except date” can be set under “WEEK”of the schedule , and the “once date” can be set at the “ONCE”of the schedule.
-
ECO (sets maximum and minimum allowable temperature set points) Cool Only/ Heat Only and DST can be set based on actual requirement.
Part info for central controller
Power (12V, GND): 12V DC, please pay attention to +-of power.
Fire alarm linkage contact (ALARM1, ALARM2): AC works normally when closed and
all AC turned off when open circuit. If no fire alarm linkage needed, should
short circuit the ALARM1 and ALARM2.
Third party interface (B1, A1): A1 should be connected to 485+ while B1 485-.
Communication port (B2, A2): It is used for connecting converter, please pay
attention to +-.
A2 should be connected to 485+ while B2 485-.

System structure chart when controlling MRV:
Central controller RWV09
When applying central controller, it is required to set address by dip switch
for easy checking and maintenance
For every system of AC, address starts from No. 1 to last indoor unit of the
system. If totally 20 indoor units are connected in one system, address should
be 1-20, if 50 in one system, address should be 1-50, the biggest address is
64.
Note: every indoor address starts from 1.
If one indoor unit is connected to converter (ADV05 addressed as No. 1, and
its central address is No. 6, the indoor code displayed on central controller
is AIRCON-1_6, if
one indoor unit is connected to converter (ADV05 addressed as No. 5, and its
central address is No. 20, the indoor code displayed on central controller is
AIRCON-5_20.
Note: The central controller RWV09 can control maximum 32 ADV05 and
maximum 64 indoor units.

Wiring diagram between central controller and converter gateway
ADV05.
All of the communication 485 cables between each module and terminal module to the central controller are double core shielded twisted-pair cable. Specific wiring as the table below:
| The length of signal line | Wiring dimension |
|---|---|
| ≤100 | 0.3 mm2 ×2 |
| 100<x≤200 | 0.5mm2 ×2 |
| 200<x≤300 | 0.75mm2 ×2 |
| 300<x≤400 | 1.25mm ×2 |
| 400<x≤500 | 2mm2 ×2 |
Installation condition
Don’t install near devices that produce electrical interference such as AC
motor, radio transmitters like network routers and consumer electronics.
Other electrical noise producers could include computers, auto-door openers,
elevators, or other equipment what can produce noise.
Don’t install in wet locations.
It will cause failure if you install in a place that shakes violently.
Don’t install in the place where it is exposed to direct sunlight or near to
the heat. This will cause failure.
Mounting Control
First, attach the mounting plate to the wall. Using a job box is preferred.
Use A and B holes for an 86mm box, use C and D holes for a 120mm box. Please
take note of the UP indicator.
Wiring diagram and Installation
Place the board, AB for 86 cassettes, CD for 120 cassettes. The hanger should
be fixed as the picture, please note the UP direction.
The hanging plate is placed in the direction of the illustration, where A/B is
the location of the 86 cassette screws, and the C/D is the position of the 120
cassette screws.
The pendant is fixed to the hole of the pendant, please pay attention to the
UP direction.
Wiring between power adapter and central controller.
Fix the screw through the bracket on the 86 cassettes and connect the
connection. The adapter’s AC IN connects to the L and N of 220V, the V+ (RED)
collector of the AC OUT, and the AC OUT. Please pay attention to the line
order. Then the central controller is fixed down.
Notes:
- B1A1 is a third party interface, paying attention to the line order.
- B2A2 for 485 interface, access to ADV05 485 B and A, pay attention to line order.
- ALARM1 and ALARM2 factory default is connected, if not be connected, then the main interface of the central controller will display alarm information, and all indoor units will be turned off.
- Third party interface
Through the A1B1 interface, it can access third party devices, and can realize the monitoring and control of third party devices to the central controller.
