Overview

The RD1xx Controller from AuVerte is part of a modern room automation solution. The principal applications of the RD1xx are bridging the RF communication of a room automation system towards a distributed actuator and sensor installation. In cases where it is not feasible to wire a load or a sensor back to a load center, the RD1xx is ideally suited to perform a limited number of operations in close proximity to the controlled load. To accommodate various application profiles, the RD1xx is available in several different models. While based on the same PCBA (printed circuit board assembly) design, the variants differ in the electronic components that are assembled on the PCBA and the software that operates the device.

Model RD101: Infrared Split HVAC Controller

The RD101 is applicable in spaces where the HVAC unit is controlled with an IR code. This is commonly the case with lower end split or VRV/VRF HVAC systems.
The RD101 receives control commands from one of the AuVerte thermostat models and translates the desired control setting into an HVAC model compatible IR code.
As the RD101 is typically placed near the IR receiver of the HVAC unit, this control is veryrobust, and the common limitations of a line-of-sight control do not apply. The compact size of the RD101 allows it to be placed inside the HVAC housing. With the strength of the on-board IR transponder, reliable IR transmission can be achieved through the housing reflections. In most instances, the HVAC unit can be used to source the power for the RD101 which makes the wiring extremely effective and simple. AuVerte has a flexible IR driver technology which allows loading the room compatible IR driver during deployment and commissioning. This capability extends that each room can have a different HVAC model and the respective IR driver can be assigned on per- room basis.
The wiring of the RD101 is shown to the right. Connect pin 1 (brown) to GND and pin 2 (red) to 12VDC.

Model RD102: RF-Bridge

Many AuVerte controllers contain a built-in RF radio transceiver. This capability allows a device to directly participate in a distributed room automation system. Such a controller that features a built-in RF radio is for example the DIN-rail mountable DM102 relay controller. On occasion however, and most often required by electrical code, these controllers are mounted inside a sheet metal enclosure. In such circumstances, it might not be possible to establish a sufficiently robust RF link between the devices inside the sheet metal enclosure and the devices that are outside the enclosure. To overcome this limitation, one of the controllers inside the sheet metal enclosure connects with the RD102 (RF Bridge) device that will be placed outside the enclosure. In such an application, the RD102will provide the full RF performance for all the devices inside the sheet metal enclosure as the different controllers mounted inside the enclosure are daisy-chained and share the RD102 link with the outside world.

In the image above, we see the RD102 on the left side. It is connected with the four-wire harness to the DM102 controller on the left. This controller in turn daisy chains with the DM102 controller on the right. A single off-the- shelf power supply will provide the necessary power for all the devices.

Model RD103: Mitsubishi Electric VRF Controller

The RD103 is an embeddable controller that is mounted inside most VRF indoor units by Mitsubishi Electric. Sample indoor units are for example the Mr. Slim product line by Mitsubishi. With an AuVerte provided dedicated harness, the RD103 connects directly to one of the headers of the Mitsubishi indoor units. As the housing of the indoor unit is made of plastic, the RD103 can be mounted inside the indoor unit enclosure and therefore is not visible from the outside. Communicating with RF, the RD103ME receives control signals from one of the different AuVerte thermostats.

In the image above we see a typical setup with a Mitsubishi VRF system. Normally, each space contains only a single indoor unit however the image shows that the solution can be scaled to many indoor units that are controlled from a single thermostat. Such a situation can arise in large spaces such as large hotel rooms and suites, function rooms such as gyms and offices, etc.

Model RD104: Master Contactor

The main application of the RD104 is to drive high-wattage master contactor application. For example, the room occupancy status can be routed to one or two relays that control the power to all the lights, outlets and fixed appliances, such as HVAC, TV or other electrical appliances.
The RD104 can drive one or two external relays. In many instances, the relay assembly that is operated by the RD104 is sourced locally by the system integrator. Figure 1 is an example of an offthe-shelf relay assembly that contains two 240VAC/30A power relays by Potter & Brumfield. These relays have each a 12VDC coil and can be directly operated from the RD104 controller. This assembly can be Din-rail mounted and if enclosed in a sheet metal box, the RD10x device would be outside this enclosure for proper working of the Rf link with the rest of the system.
Figure 2 shows a panel-mount relay. The RD10x device can directly operate the 12VDC relay coil. Such relays can be sourced locally by the system integrator. Again, as in the example above, if the relay is housed inside a sheet metal enclosure for safety reasons, the RD10x device should be placed outside to facilitate the proper working of the Rf links. An additional possibility is that the RD10x can control a RIB (Relay in a box) device. As before, these devices are readily available and can be sourced by the system integrator.

Model RD105: Digital In/Out

Figure 3Din-rail mounted dual-relay assembly compatible with the RD105
The RD105 is a general-purpose input/output controller. The pins can be configured at system design time to perform application specific functions. Some select examples of how the RD105 can be applied:

• Extend an Ondur thermostat to operate the open/close windings of a motorized proportional valve.
• Extend an Ondur thermostat and operate secondary or tertiary heating stages.
• Signal room occupancy as a dry-contact input to a third-party system.

Figure 3 shows an example if the RD105 is used to operate two general purpose relays. In this case, a relay of moderate contact rating is used and the contacts can be used to operate in the aforenoted applications.
Below, are example wiring diagrams is the RD105 is used in a low-voltage application.
