3 Locking and function of operating mode keys Locking of operating mode keys The operating mode keys Overtime operation, Ventilation and Stop can be blocked individually, if required; see also page 13, Activation (blocking) of operating mode keys. Window Alarm Operating mode keys (4) Setting keys (5) Control panel The control panel is equipped with a 2 x 20 character window of the LED backlight type, where the operating status, air flow, temperatures and other setting values and parameters are displayed in clear text; see Fig. 20. Four operating mode keys are used to select the desired operating status. The current operating status is shown in the operating menu in the window. Each operating status can be interrupted at any time for a new operating status by pressing the appropriate operating mode key. Five setting keys are provided to set and read the air flows and temperatures, etc., to increase and reduce the values, and to move around in the menu structure. The values are displayed in the setting menu on the window. The red LED on the panel will flash in the event of a fault function. The fault function is displayed in the alarm menu in the window.

4 Activation, locking and function of setting keys Activation of setting keys Press down the setting keys simultaneously for 5 seconds. Activation is confirmed by a new text and a number appearing in the display. The window contains the number and the text. It is now possible to change the desired value and operating times, etc. Locking of setting keys The setting keys can be blocked via a terminal on the control card. The lock is activated by jumping terminals 23 and 24. Function of setting keys. Used to move to the next window at the same menu level..

The main menu is numbered in tens -, 20, etc., and the windows in sub-menu 1 beneath window in the main menu are numbered singly - 11, 12, etc. Certain sub-menus also include a sub-menu 2. The windows in sub-menu 2 under window 12 in sub-menu 1 are identified with a letter in addition to the number - 12a, 12b, etc. Moving around in the same menu level is done with the key. Moving down one step to a sub-menu is done with the key. Moving up one step, e.g. from a sub-menu to the main menu, is done with the key. The Plus and Minus keys are used to change a numerical or text parameter. The parameter value then begins to flash at the same time as it is changed. Acknowledgement of the value is done with the key. The parameter value then stops flashing Main menu 70 Huvudmeny Fig. 22.

5 Commissioning - start-up Factory settings on delivery Self-test and Calibration are always carried out prior to delivery from the factory. Setting and checking the function are adapted to suit the ordered variant and the specified accessories. The following functions/accessories influence the setting: Electric coil installed Cooling installed Presence sensor as an accessory Example: Changing standard flow The standard flow must be changed from 200 l/s to 220 l/s. Activation of the setting keys brings you automatically into the main menu with window number. Press key to show window 11 Press key Press key until 220 l/s is displayed to confirm Calibration of unit The unit must always be calibrated for a new installation. The calibration time is approx. 5 minutes. During calibration the control unit checks the prevailing operating condition and adapts the operating point of thefans to the selected setting data. Interrupted calibration In the event of a power supply failure or other operating breakdown which interrupts calibration before it is complete the calibration procedure must be repeated Sub-menu Undermeny Normalflöde: Standard flow: l/s l/s Unit self-test Self-test is intended to be used for checking important components in the unit during service and after correcting any faults. The self-test time is approx. 20 minutes Ställ Set desired value in börvärde Main menu Huvudmeny Alarm In the event of an alarm, the response should be as indicated in the alarm message (see also PROCEDURE - Alarm and fault-finding). Activate self-test by pressing AUTO twice. The unit switches automatically to automatic mode once self-test is complete. The self-test time depends on the type of fault Fig. 23. Example: Changing standard flow. 40 Selecting operating mode STOP It is recommended that the unit is operated continuously for normal air treatment. In order to be able to select the STOP operating mode, dampers are required in the outdoor air and the extract air duct. The absence of a damper will allow impurities to enter the unit by the back way, and the room and the unit will be cooled down during cold times of the year. Cooling of the room leads to increased heating costs and increases the risk of operating breakdowns with the unit.
