  • Page 3: Introduction

    Important: In order to confirm whether a particular device or application program incorporates the fan coil analog function, please refer to the device user manual, as there may be significant differences between the functionality of each Zennio device.

  • Page 4: Configuration

    Fan Coil ‘Analog’ 2 CONFIGURATION Please note that the screenshots and object names shown next may be slightly different depending on the device and on the application program. 2.1 CONFIGURATION After enabling the module, in the general configuration of the device, the "Fan Coil" tab will be available in the ETS tab tree.
  • Page 5 (thus improving the user comfort) even when the valve is closed. See ANNEX I. Automatic Air Recirculation in Cooling Mode. Initialization: enables to configure the behaviour of the 'Analog' fan coil module after a bus fault or an ETS download. See section 2.2.3.
  • Page 6 Fan Coil ‘Analog’ ETS PARAMETERISATION After enabling the Fan Coil X, in the "Configuration" tab (see section 2.1), a new tab of the same name is added to the left tree. Figure 3. Fan Coil X - General Configuration. Type of Fan Coil [2 Pipes / Pipes].

  • Page 7: Valve

    Initialization [Default / Custom]: enables configuration of the behaviour of the Fan Coil 'Analog' module after a bus failure or an ETS download. If the "Custom" option is selected, the "Initialization" sub-tab is enabled. See section 2.2.3. 2.2.1 VALVE This section details the valve settings that are common for both modes, heating or cooling.
  • Page 8 Fan Coil ‘Analog’ The objects that will store the output control value, "[FCn] Valve: Control" (for fan coil of two pipes) and "[FCn] Cooling Valve: Control" and "[FCn] Heating Valve: Control" (for fan coil of four pipes), must be linked to the appropriate actuator.
  • Page 9 Fan Coil ‘Analog’ ETS PARAMETERISATION This section includes all parameters related to the configuration of the cooling and heating valves. Figure 4. Fan Coil - Cooling/Heating Valve: Control Signal Scaling. The parameters are the following: Control Signal Scaling ➢ Minimum Input Value (X1) [0…100][%]: defines the minimum regulation value to be received from the thermostat that will cause the valve to start opening.
  • Page 10 Fan Coil ‘Analog’ ➢ Maximum Output Value (Y2) [0…100] [%]: defines the maximum operating value of the valve, maximum opening position. Note: If, as a result of a parameterisation error, the minimum value of the control signal (input or output) is greater than a maximum value, 0% (minimum) and 100% (maximum) will be taken as control signal scaling range.

    Fan Coil ‘Analog’ 2.2.2 FAN The fan features an automatic control, in which its speed is calculated by the module itself and an external reference, and a manual control, in which the fan speed will be controlled externally. For both modes the fan speed will always comply a minimum and a maximum allowed speed.
  • Page 12 Fan Coil ‘Analog’ ETS PARAMETERISATION Figure 6. Fan Coil - Fan. / Manual / Automatic + Manual]. If “Automatic + Manual” Control Mode [Automatic is selected, the parameters corresponding to the mode change are displayed: ➢ Mode after ETS Download [Automatic / Manual].
  • Page 13 Fan Coil ‘Analog’ time can be modified through the object "[FCx] Manual Fan: Manual Control Duration". Fan Speed Control. An input signal to control the fan coil generates an output value according to the following parameterisable limits: ➢ Minimum value [1...20...100][%]. For any input control value that causes an output lower than this limit, the output will be equal to the minimum value.

  • Page 14: Initialisation

    After a bus failure the module, by default, will keep its previous state. This tab offers the possibility to configure the initialization of the Fan Coil 'Analog' module by defining aspects such as its initial state or whether an update of the input objects and/or the sending of certain status objects is required after start-up.
  • Page 15 Fan Coil ‘Analog’ / Off]. If “Previous” is selected, the status before the failure Initial Status [Previous status shall be maintained, except after programming, in which case the output will be off. Input Objects Update [disabled/enabled]: if enabled, a reading of the input objects will be carried out after a bus fault or ETS download.
