Standard Control: Resistance
In Resistance Control Mode the RTD-
10 Inputs allow individual control of
a/c unit operating parameters using
resistance values. Each input
corresponds to a specific unit setting
shown in the table below If an input is
left unconnected then the
corresponding setting will remain at
the default value.

Caution: Relays rated for maximum 1A, 24VAC/30VDC
Resistances should be within +/-250 ohms of the quoted value. Open circuit is R>200k.
S1 in resistance mode is designed to be operated using a linear 10k variable resistance.
It is recommended that volt-free contacts or switch mechanisms have gold plated contacts to ensure a low
resistance circuit when the switch is made.
S1 to S6 cables should be 0.5 to 1.0 mm

multi-stranded screened twisted pair. The screen should be earthed
at one end only. The maximum distance from the RTD-10 to the input source is 200m.

MOUNTING PILLARS
The RTD-10 is supplied with 4
mounting pillars that can be used to
mount the interface within units with
compatible mounting holes
SCREW MOUNTING
The RTD-10 can be mounted using
screws of up to 5mm diameter.
The RTD-10 can be mounted horizontally or vertically.
Power Supply
The RTD-10 requires a 15V to 24VDC power connection. Power can be
supplied from VRV indoor unit PCB X18A connection , a Skyair indoor unit
PCB X35A connection or VAM PCB X11A connection. A 1m cable and
connector is supplied with the RTD-10.
RTD-10 Description
The RTD-10 is a monitoring and control interface for Daikin VRV and Skyair
ranges of air-conditioners; and VAM and VKM ventilation units. The interface is
compatible with all units that have a P1,P2 remote controller network
connection and allows control of up to 16 units in a single group.
Control Functions
HARDWIRED CONTROL. Unit control can be achieved through resistance
inputs using resistor, potentiometer and volt-free contact inputs.
BMS INTEGRATION. Unit control can be achieved through 1-10V voltage
inputs integrated with BMS control outputs.
HEATING INTERLOCK. Units can be interlocked with external heating
systems.
DUTY/STANDBY. Multiple groups can be operated with rotating duty/standby
with fault and high temperature alarming.
MODBUS CONTROL. The RTD supports the Modbus Protocol for network
control and monitoring.
CUSTOM CONTROL. RTD interfaces can be supplied in custom configurations
to suit specific applications.
Warnings and Cautions
Do not exceed the specified fault relay ratings
Observe precautions for handling Electrostatic
Sensitive Devices

Installation and Operating Instructions
P1,P2 Network
Terminals P1, P2 connect to the Daikin P1, P2 network. P1,P2 installation
should follow Daikin installation specifications. The RTD-10 can operate in
Master or Slave mode with any Daikin remote controller. Operation is also
possible without a remote controller being connected. Note that infra-red
receivers must be configured to operate in slave mode.
The RTD-10 can be configured to operate in several different modes using the
configuration DIP switches SW1.1 to SW1.4. In Standard Control the following
combinations of modes are available:
