S25 www.blaubergventilatoren.de UNIT MOUNTING AND OPERATION SAFETY PRECAUTIONS • Disconnect the unit from power mains prior to any installation operations. • Do not operate the unit outside the temperature range stated in the user's manual. • Do not operate the unit in aggressive or explosive environments. • Do not lay the power cable of the unit in close proximity to heating equipment. • While installing the unit follow the safety regulations specific to the use of electric tools.
S25 www.blaubergventilatoren.de PURPOSE THE UNIT SHOULD NOT BE OPERATED BY CHILDREN OR PERSONS WITH REDUCED PHYSICAL, MENTAL, OR SENSORY CAPACITIES, OR THOSE WITHOUT THE APPROPRIATE TRAINING. THE UNIT MUST BE INSTALLED AND CONNECTED ONLY BY PROPERLY QUALIFIED PERSONNEL AFTER THE APPROPRIATE BRIEFING. THE CHOICE OF UNIT INSTALLATION LOCATION MUST PREVENT UNAUTHORISED ACCESS BY UNATTENDED CHILDREN.
S25 www.blaubergventilatoren.de INSTALLATION, CONNECTION TO POWER MAINS AND SET-UP CUT OFF POWER SUPPLY BEFORE ANY OPERATIONS ARE PERFORMED. DO NOT LAY THE CABLE IN CLOSE PROXIMITY TO THE CONTROL PANEL CABLE! WHILE ROUTING THE CONTROL PANEL CABLE DO NOT COIL THE EXTRA LENGTH. All devices must be connected to an RS-485 network in a multidrop bus.
S25 www.blaubergventilatoren.de CONTROL PANEL WALL SURFACE MOUNTING 1. Route the control cable to the control panel mounting location. The control cable must be permanently laid in the wall of the building. • • 2. Use a screwdriver to carefully press on the latch on the unit casing end face and separate the casing halves. DIP switch Rocker 1 must be set to OFF. This rocker is to be only used by service engineers for programming the control panel.
S25 3. Route the cable through a round hole in the back side of the panel and attach the panel to the mounting surface. Insert the connector into the bracket. www.blaubergventilatoren.de 4. Connect the power supply cable wires according to the electrical connections diagram. X1 B 24V GND A ° 6. Match the prongs of the lower part of the front panel with the slots in the lower part of the back panel at 45° and join the halves until they lock in place. 45 5.
S25 www.blaubergventilatoren.de NETWORK SETUP An RS-485 network is based on a multi-master principle: • • Slave devices — all the AHUs. Master devices — all the control panels, external sensors, a smart home system etc. RS-485 network factory settings: • • • • Controller address: 1. Data transfer rate: 115200 baud. Stop bits: 2. Parity: none. ATTENTION! The RS-485 network parameters for the AHU controller are set up via the mobile application.
S25 www.blaubergventilatoren.de CONTROL Main page Buttons: — unit ON/OFF (Standby mode activation). 2 — press the arrows as many times as necessary to select the desired pre-set speed. — manual speed selection mode (from the minimum permissible pre-set value to 100 %). 50 % % — displayed upon pressing , adjust the speed (up/down) by pressing the arrows as many times as necessary. To revert to the preset speeds, press the percentage icon % .
S25 www.blaubergventilatoren.de BASIC SETTINGS MENU Main page Menu Basic settings Main page Menu Basic settings Temperature 15 ˚C — set the desired temperature in the room and select from the list of air temperature control options: Ventilation — the unit only works in the heat recovery mode. Heating — the unit automatically warms the air to a pre-set level by activating the heater or using the outdoor air heat.
S25 Main page www.blaubergventilatoren.de Menu Basic settings Schedule The weekly schedule contains four time periods for each day of the week. Once the weekly schedule is enabled in the Main page window, the air handling unit will run to a schedule using the following parameters: 2 — pre-set speed selection: 0 (Standby), 1, 2, 3 … 6 : 0 - 9 : 0 — setting the end for the selected time period. The first time period always begins at 00:00 while the following periods begin when the previous ones end.
S25 www.blaubergventilatoren.de Main page Menu Alarms Current alarms 0 — number of current alarms. Indicates a serious malfunction. The unit is forced to shut down. The alarms must be reset manually. Alarms 0 — number of current warnings. The unit is not forced to shut down. Warnings are reset automatically once the causes have been addressed. Warnings 5 — Code 5 — current alarm/warning code. The malfunction codes are detailed below.
S25 www.blaubergventilatoren.de ENGINEERING MENU Main page Menu Engineering menu To access the Engineering Menu, enter the password (set to 1111 by default). The password can be changed via the Engineering menu. To reset the password, set the air handling unit to the Setup mode using the buttons on the AHU casing (see the AHU user's manual), enter the temporary password (1111) in the Engineering menu and replace it with a permanent one. Note: the engineering menu requires expert skills.
S25 www.blaubergventilatoren.de Main page Menu Engineering menu Sensors ... Main (RH/CO2/VOC/PM2.5) sensor — a wired sensor connected to the control circuit board. External (RH/CO2/VOC/PM2.5) sensor — a remote sensor which can be contained inside the other control panel or a special external device connected via RS-485, Wi-Fi or Ethernet. Once the respective main sensor or external sensor is enabled, the unit starts responding to it.
S25 Main page www.blaubergventilatoren.de Menu Engineering menu Main heater Select the heater type and set up its parameters. Note: if the water heater is active, prior to disabling it make sure that the heat-transfer medium supply has been disconnected and that the circuit has been drained to avoid damaging the water heater by disabling it during the cold season.
S25 www.blaubergventilatoren.de Main page Menu Engineering menu Cooler Select the cooler type (discrete/analogue) and its operation mode. Min. time before OFF — the minimum time for the cooler operation before deactivation. Min. time before ON — the minimum time for the cooler idling before re-activation. Cooler hysteresis — only available for coolers with discrete control.
S25 Main page www.blaubergventilatoren.de Menu Engineering menu Firmware This window displays the information about the firmware installed on the AHU and the control panels. Main page Menu Engineering menu Factory settings The reset may cause a temporary loss of connection to the device as it affects the Wi-Fi, RS-485 and Ethernet settings. If necessary, repeat the Wi-Fi, RS-485, and Ethernet parameter setup using the mobile application (see the "Wireless control system" manual).
S25 www.blaubergventilatoren.de ALARM AND WARNING CODES Code Description 0 Alarm! Supply fan malfunction. • Determined depending on a specific configuration. • By rpm: if the supply fan speed drops below 300 rpm for 30 seconds (configurable within a 5 to 120 second range). • By discrete input: if the discrete input (ТAНО М1) remains open for 30 seconds (configurable within a 5 to 120 second range) provided that the supply fan must be running. Alarm! Extract fan malfunction.
