IRIO/TWS includes 4 on/off control circuits for lighting control using mechanical 2-way switches and 2 x 0-10V outputs for dimming.
Each lighting circuit consists of a Latching Relay (for on/off control) and a Current Sensor to sense the state of the light.
Latching Relays remain at the last Open/Close state without current in the relay coil, to save energy.
As conventional switches and wiring are used, mechanical 2-way switch control is retained, even if Comfort or IRIO is not working.
The diagram shows how IRIO/TWS can control a light via a 2-way switch. The IRIO/TWS can be mounted in the ceiling and connected to the mechanical 2-way switch. The only change from conventional wiring is that an additional switch wire is required for the 2-way switch. By this arrangement, the mechanical switch will continue to work even if the IRIO/TWS becomes faulty.
The IRIO01 Intelligent Remote Input/Output Modules are a series of general purpose automation products capable of a wide range of control functions including Digital Inputs, Digital Outputs, Analog Inputs (0-10V), Analog Outputs (0-10V), and Temperature and Light Level Sensing. This allows the control of HVAC, Blinds, Infrared signal transmission, and Two-Way Switch Lighting.
IRIO modules are easy to program and require little wiring. Up to 15 IRIOs can be installed in a system, which can be controlled by the Comfort Alarm/Automation System, LGX01 Logic Engine, or the UCM/Logic Controller. IRIO can be used in standalone mode when no control from other systems or other IRIOs is required.
Free mobile apps can be used to view the status and control connected lighting as well as blinds, heating, air-conditioners and other appliances.
Interfaces between IRIO and Modbus, KNX, C-Bus and Hotel I/O are possible via Cytech UCM Interfaces.

Each lighting switch is mapped to 3 Flags and a Sensor. Setting or clearing the Flag switches the light on or off. The Actual status of the light is always updated to the Control/Feedback Flag.
The mapped Sensor shows the current level measured by the built in current sensor. The Current sensing threshold sets the current level which determines the light to be OFF or ON to cater for lights of different efficiencies. The Sensitivity Level selects one of 2 sensitivity levels, high sensitivity for low current lights like LED lights, and low sensivity for conventional lights.
Each IRIO/TWS also includes 2 x 0-10V outputs for the control of suitable dimmable lights. Each 0-10V output is mapped to a Counter so that setting a value to the counter sets the dimming level between 0 and 255. The Full Scale Level can have the counter set at 255 or 99. Travel Time is the time taken for the voltage to go from 0 to 10 and vice versa. On Level is either Full Bright or Last Level (memory) when the output is switched on to full scale.
Up to 15 IRIO modules (including IRIO/TWS, IRIO/Blinds, IRIO/IO, IRIO/IR) can be installed in an RS485 Bus network with a UCM/Logic or LGX01 Bus Controller. LGX Logic Engine has 8 Inputs and Outputs. UCM/Logic is a low cost controller with no Inputs and Outputs. Cytech's KNX, C-Bus, Modbus and other 3rd party interfaces can be connected to the same Rs485 Bus for further integration.
