The IRIO01 or Intelligent Remote Input/Output Module is a general purpose automation
module with 8 inputs and 8 outputs. The IRIO has the flexibility to be configured for a
variety of automation functions by plugging in a selection of submodules into 2 slots. Up
to 15 IRIOs can be installed in a Comfort System.
The IRIO handles the automation functions in Comfort in a way that is easier to program
and reduces wiring. Instead of programming Responses and Actions, Functions are
selected, and mapped to Comfort registers like Flags, Counters and Sensors. For
example, the Heating or Cooling function works by assigning the setpoint to a Counter
and temperature to a Sensor Register. Putting a value into a Counter changes the
setpoint, and comparing the temperature in the sensor register allows the IRIO to decide
whether to turn on the heating/cooling relay.
The function is mapped to a Comfort Flag, so that setting the flag will start the function
and clearing the flag disables it. The temperature is obtained from a TSM (Temp sensor
module) thermistor in the Temp Sensor Input function or other means, e.g. via KNX,
C-Bus or the TSM Temperature Sensor Module.
The TWS submodule for control of lighting by two way switch reduces wiring as it is not
necessary to connect Inputs and outputs to Comfort. This submodule allows the current
threshold to be adjusted so that it is able to handle all different lighting loads even low
current LED lighting.
The Blinds submodule controls a Blinds motor without needing a separate Blinds
controller. It is able to move the blinds up and down as well as position the blinds
anywhere with the help of a built-in current sensor.
In some circumstances, the IRIO can operate stand-alone without the Comfort controller, if the IRIO input and output is mapped to the same Flag or Counter.
Each IRIO can accept two plug-in submodules from the list below;
- ISM01 Digital I/O submodule
- ISM02 Digital Outputs/Analog Inputs submodule
- ISM03 IR (Infrared) submodule with current sensor
- ISM04 Two Way Switch submodule
- ISM05 Blinds submodule
- ISM06 NO/NC relay submodule
- ISM07 Relay I/O submodule
Note that the submodules are not included in IRIO. They are ordered separately as
required. The IRIO can work with 1 or no submodules. The IRIO will detect what
submodule is plugged in.
The IRIO baseboard has 2 programmable analog outputs (0-10V) for dimming and
control which are always available.
Each Submodule may support Output functions and Input functions depending on which
are supported by the submodule. Not all functions are supported by each submodule.
Output functions include;
- 2 speed/3 speed fan
- Air-con Interface
- IR signal
- TWS (Two way switch)
Input functions include;
- Pulse count
- Current sensing
- Analog Input 0-10V
- Temp Sensor
Submodules can have 0, 2, or 4 Inputs.
Each submodule can only select the appropriate Output and Input function that is
applicable for the hardware. Only the applicable functions for each submodule can be
selected by Comfigurator. The table below shows the Output and Input functions
available for each submodule.
