  • Page 5: Introduction

    1 INTRODUCTION 1.1 MAXinBOX FC 0-10V FAN MAXinBOX FC 0-10V FAN from Zennio is a versatile KNX multi-function actuator that aims at fulfilling the climate control needs of KNX environments with integrated fan coil units where the fan speed is controlled through an analogue 0-10 VDC signal, while the gates of the water pipes need to be controlled through binary outputs (relays).
  • Page 6 Heartbeat or periodical “still-alive” notification. The MAXinBOX FC 0-10V FAN application program focuses on the control of fan coil drives that consist of two or four pipes (each with its own open/close valve) and a fan system whose speed is controlled through a 0 to 10 VDC analogue signal (more voltage means more speed).

  • Page 7: Installation

    MAXinBOX FC 0-10V FAN 1.2 INSTALLATION MAXinBOX FC 0-10V FAN connects to the KNX bus through the on-board KNX connector. Once the device is provided with power from the KNX bus, both the individual address and the associated application program may be downloaded.

  • Page 8: Start-Up And Power Loss

    Please consult the next sections of this document for further details. On the other hand, when a bus power failure takes place, MAXinBOX FC 0-10V FAN will interrupt any pending actions, and will save its state so it can be recovered once the power supply is restored.

  • Page 9: Configuration

    MAXinBOX FC 0-10V FAN 2 CONFIGURATION After importing the corresponding database in ETS and adding the device into the topology of the desired project, the configuration process begins by entering the Parameters tab of the device. 2.1 GENERAL The first parameterisable screen available by default is “General”. From this screen it is possible to activate/deactivate all the required functionality.

Sending of Indication objects on bus voltage recovery Heartbeat (Periodical Alive Notification): this parameter lets the integrator incorporate a one-bit object to the project (“[Heartbeat] Object to Send ‘1’”)

  • Page 11: Inputs

    It is possible to connect motion detectors (models ZN1IO-DETEC-P and ZN1IO- DETEC-X from Zennio) to the input ports of MAXinBOX FC 0-10V FAN. This brings the device with the possibility of monitoring motion and presence in the room, as well as the light level.
  • Page 12 Motion detectors with references ZN1IO-DETEC and ZN1IO-DETEC-N are not compatible with MAXinBOX FC 0-10V FAN (may report inaccurate measurements if connected to this device). When connected to MAXinBOX FC 0-10V FAN, the rear micro-switch of model ZN1IO-DETEC-P should be set to position “Type B”. http://www.zennio.com Technical Support: http://support.zennio.com...

  • Page 13: Binary Outputs

    MAXinBOX FC 0-10V FAN 2.3 BINARY OUTPUTS MAXinBOX FC 0-10V FAN incorporates four binary outputs, each of which can be enabled and configured in parameters independently. Although in this device they are offered with the aim of controlling the gate valves of the fan coil tubes (up to four), their parameterisation is similar to that of the individual relay outputs of any other MAXinBOX actuators.

  • Page 14: 0-10V Analogue Outputs

    MAXinBOX FC 0-10V FAN 2.4 0-10V ANALOGUE OUTPUTS MAXinBOX FC 0-10V FAN incorporates two analogue voltage outputs that provide a voltage signal in the range 0 to 10 VDC. This voltage will be in accordance to the percentage values that are received through a specific communication object.
  • Page 15 MAXinBOX FC 0-10V FAN After enabling any of them, two objects are included by default: “[AOx] Output Value (Control)”: this object is supposed to receive percentage values from the KNX bus, making the device generate a voltage output between 0 V and 10 V (proportional to the percentage value).
  • Page 16 MAXinBOX FC 0-10V FAN Initialization: brings the option to set the output to a particular state at the start-up of the actuator. ➢ Default: off after an ETS download, and unchanged after a bus power failure. ➢ Custom: this option brings two new parameters: •...

    MAXinBOX FC 0-10V FAN 2.5 FAN COILS MAXinBOX FC 0-10V FAN incorporates two independent fan coil functions that implement all the logic involved in the control of up to two fan coil units. ETS PARAMETERISATION After enabling “Fan Coils” in the General screen (see section 2.1), a new tab will be incorporated into the tree on the left.

  • Page 20: Advanced Settings

    MAXinBOX FC 0-10V FAN Minimum Fan Speed: from 0 to 100% (20% by default). This value must be higher or equal than the Minimum Control. Note: both offsets must be lower than the Maximum Fan Speed parameter (see 2.5.1.2). Depending on the mode, the following delays must be configured: Delay for Fan Activation when Valve Opens: time to wait since the valve opens until the fan can be turned on.

  • Page 22 MAXinBOX FC 0-10V FAN Any control order is ignored, but taken into account after leaving this mode. The forced position resumes after a power failure. An Off order will be performed as usual, and leads to leaving the forced position mode.
  • Page 23 MAXinBOX FC 0-10V FAN ETS PARAMETERISATION After enabling “Advanced Settings” in the Configuration screen of the fan coil function, a new tab will be incorporated into the tree on the left. Figure 13 Fan Coil X – Advanced Settings. The following parameters can be configured: Fan Coil Always On?: sets whether the fan coil will always be on or not.

  • Page 27: Manual Control

    MAXinBOX FC 0-10V FAN 2.8 MANUAL CONTROL MAXinBOX FC 0-10V FAN allows manually switching the state of its binary and 0-10V analogue outputs through the respective pushbuttons on the top of the device. A specific pushbutton is therefore available per output.
  • Page 28 MAXinBOX FC 0-10V FAN The action performed depends on the output type and, in the case of 0-10V analogue outputs, on the press type. For both outputs types, the presses have no effect if the output is disabled in parameters.
  • Page 29 MAXinBOX FC 0-10V FAN Depending on the type of output, binary or analogue, the reactions to the button presses will differ. Binary output: short or long-pressing the button will commute the on-off state of the relay. 0-10V analogue output: the behaviour is the same as described for the Test Off Mode, except that the fan status objects do not change (they will be updated when leaving the Test On Mode).
  • Page 30 MAXinBOX FC 0-10V FAN stated before, using the Test Off mode does not require any special action, while switching to the Test On mode does require long-pressing the Prog./Test button. Manual Control Lock: unless the above parameter has been “Disabled”, enabling the Lock Manual Control parameter will provide a runtime procedure for locking the manual control.

  • Page 31: Master Light

    The Master Light function brings the option to monitor the state of up to 12 light sources (or even more, if the Master Light controls from multiple Zennio devices are linked together) or of any other elements whose state is transmitted through a binary object and, depending on those states, perform a master order every time a certain trigger signal (again, a binary value) is received through a specific object.
  • Page 32 MAXinBOX FC 0-10V FAN ETS PARAMETERISATION Once the Master Light function has been enabled, a specific tab will be included in the menu on the left. This new parameter screen () contains the following options: Number of State Objects: defines the number of 1-bit status objects required.
