VAV Control (variable airfl ow), with CO sensor or similar CAD-COMPACT BASIC units are equipped with EC motors. The motors have specifi c terminals to receive a re- gulation signal to control fan speed (0-10V).

    mined experimentally during the system start-up process. CAD-COMPACT BASIC units are equipped with EC motors. The motors have specifi c terminals to receive a regu- lation signal to control fan speed (0-10V). The 0V signal corresponds to the fan stop, while the signal of 10V corresponds to fan maximum speed. To perform speed regulation in constant pressure mode, it is only necessary to have a pressure transmitter with a 0-2000ppm full scale and 0-10V output signal and connect it to the electrical panel as indicated in the electric dia- grams.
  • Page 12 To carry on this modifi cation it is necessary to make the following modifi cations to the unit: 1. Exchange the supply and extract fi lters as well as the access covers to the fi lters. 2. Replace the labels that identify the function of the air inlet/outlet. To do this, a new set of labels is supplied with the unit.

    8.2.2. Through integration to Modbus network (external BMS) Integration into Modbus networks is incompatible with the use of the remote control. In addition to allfunctionality available through the remote control, through the map of modbus registers it is possible to obtain the following functionalities and information: FUNCTIONALITY Automatic fan speed adjustment in COP (Constant Pressure) mode.

  • Page 15: Free-Cooling Function Setting

    8.3.2. Free-cooling function setting The heat recovery units of the CAD-COMPACT range are equipped with a by-pass damper that, when opened, allows outdoor air to be introduced in the building without being heated / cooled in the heat exchanger. (As this is a partial bypass a small percentage of air continues passing through the heat exchanger).

  • Page 16: Advanced Parameters Configuration

    8.4. ADVANCED PARAMETERS CONFIGURATION In addition to the functions that can be performed through the three buttons of the hand terminal, it is also possible to modify some of the parameters and functionalities set from factory. Depending on the parameter to be modifi ed, it will be necessary to access the electronic board of the controller (inside the electrical cabinet) or the remote hand terminal.

    8.4.3. Fan selection that acts as a master (only available on units controlled via Modbus in COP mode) Using the SW4.3 selector it is possible to defi ne which of the two fans acts as a master. The fan defi ned as mas- ter must be the one that supplies or extracts air from the network of ducts in which the pressure transmitter is installed.

    8.4.5. Filter supervision CAD-COMPACT BASIC heat recovery units are supplied with pressure switches mounted on both fi lters (supply and extraction). When the differential pressure value measured by the pressure switches exceeds 200Pa an alarm is produced. Depending on the particularities of the installation (operating hours and polution of the outdoor en- vironment) it may be advisable to change the pressure switch setting as indicated in the following table: Filters state Airfl...
