  • Page 13: Fan Coil

    MAXinBOX FC 0-10V VALVE 2.5 FAN COIL MAXinBOX FC 0-10V VALVE incorporates one fan coil module that implements all the logic involved in the control of a two-pipe or four-pipe fan coil unit where the fan speed can be switched through relay outputs and the opening and closing of the pipe valves can be commanded through a 0 to 10 VDC signal (depending on the required degree of opening).
  • Page 14 Also within the general configuration of the device, it is necessary to set the valve control type, as either local (the valves will be commanded by MAXinBOX FC 0-10V VALVE itself) or remote (the orders will be sent by MAXinBOX FC 0-10V VALVE bus to a separate valve actuator, through the KNX bus).
  • Page 15 MAXinBOX FC 0-10V VALVE ETS PARAMETERISATION Figure 6 Fan Coil – Configuration. The Configuration screen (see Figure 6) is accessible by default after enabling the Fan Coil function. It contains the following parameters: PIPE CONFIGURATION Type of Fan Coil: “2 pipes” or “4 pipes”. If “2 pipes”, it is necessary to define the available HVAC modes: ...
  • Page 16 MAXinBOX FC 0-10V VALVE FAN CONTROL CONFIGURATION Number of Fan Speeds: up to four fan speeds can be controlled, depending on the fan model. This determines the number of relays required (unneeded relay outputs may be configured as individual binary outputs; see section 2.3).
  • Page 17 MAXinBOX FC 0-10V VALVE the project topology. Ventilation mode can also activate through scenes (please refer to section 2.5.1.4). Alarms: enables or disables the alarm functions (see section 2.5.1.1). Forced Position: enables or disables the forced position function (see section 2.5.1.2).
  • Page 18 This typically translates into a greater opening of the valve (after applying the configured restrictions), which under the local valve control causes a higher-voltage signal in the analogue output of MAXinBOX FC 0-10V VALVE. For valves controlled through other voltage ranges or without a direct proportion...

  • Page 19: Alarms

    Note: alarms always prevail over any other function (i.e., any orders during the alarm state will be ignored). MAXinBOX FC 0-10V VALVE incorporates two independent alarm functions. Alarm 1 has a higher priority over alarm 2. If the fan coil module is under the “alarm 2”...
  • Page 20 MAXinBOX FC 0-10V VALVE ETS PARAMETERISATION After enabling “Alarms” in the Configuration screen (see section 2.5.1), a new tab will be incorporated into the tab tree on the left.

  • Page 21 MAXinBOX FC 0-10V VALVE Cyclical Monitoring Period: sets every how much time, at most, the alarm object should be updated from the bus after an initial reception has already taken place. If exceeded, and for safety reasons, the alarm action will be triggered as well.

  • Page 22: Forced Position

    MAXinBOX FC 0-10V VALVE 2.5.1.2 FORCED POSITION It is possible to define a forced position for the Cooling mode and another forced position for the Heating mode. Forced positions consist in a pre-set configuration for the valve opening level and for the fan speed, so that the fan coil unit adopts such configuration when the forced- position trigger object receives the value “1”.
  • Page 23 MAXinBOX FC 0-10V VALVE Moreover, objects “[FCV1] Forced Position: Cooling”, “[FCV1] Forced Position: Heating”, or both (depending on the parameterisation), will be incorporated to the project topology, together with their corresponding status objects. Regarding the parameters: Valve Position: sets, in terms of percentage, the target opening level of the valve.

  • Page 24: Purge

    MAXinBOX FC 0-10V VALVE 2.5.1.3 PURGE The configuration of the valve allows enabling a purge function (one per valve), which consists in opening the selected valve and stopping the fan for a configurable time space. The purge begins when one “1” is received through the corresponding object, and ends when the parameterised time elapses, when one “0”...
