Technical data General The Swegon CASA W130 is an ideal ventilation unit for homes and similar premises. The unit has heat recovery by means of a counter-flow plate heat exchanger. The unit can either be mounted on a base on the floor or on a separate wall mounting bracket. Casing The casing is made of double-skin sheet steel with an intervening foam plastic and mineral wool insulation. The internal and external surfaces of the ventilation unit have a powder painted and baked finish in a white tone (NCS S 0602-G). The front panel is hung on hinges, which simplifies inspection and servicing. The panel switch automatically switches off the unit when the panel is opened. Fans The fans have low-energy, economical, type EC directcurrent motors, whose power consumption is substantially lower than that of traditional fans driven by AC motors. The advantage of EC fans is that their speed is variably controllable and their efficiency is high even when they operate in the lower speed range. The power supply and control cables have quick-fit connectors and the fans can be easily removed from the unit, if required. Filters The ventilation unit has class G3 wide-meshed filters for the outdoor air and the extract air. There is also a class F7 fine filter for the supply air. Heat exchanger The plate heat exchanger which operates according to the counter-flow principle is made of thin aluminium plates. The airflows pass through separate channels into and out of the heat exchanger which ensures that smells cannot be transferred. The heat exchanger can be easily removed from the unit for inspection and servicing. The unit s automatic bypass damper steers the extract air to bypass the heat exchanger when heating is not needed. Anti-frost protection The heat exchanger is equipped with a thermostat for freeze protection. If there is a risk that the heat exchanger will freeze, the controller switches in the air heater and reduces the speed of the supply air fan, and the heated extract air prevents freezing inside the heat exchanger. Reheating In the electrically heated model, a 900 W electric air heater for reheating the air (standard equipment) is located downstream of the heat exchanger. An adjustable thermostat switches on the air heater when the supply air temperature drops below a preset value. Swegon CASA W130 Econo The Econo model has a water heated air heater, the temperature of which can be set inside the ventilation unit. Air heater, preheating A 1,000 W electric air heater for preheat located upstream of the heat exchanger is standard equipment in the ventilation unit. An adjustable thermostat switches on the air heater when the outdoor air temperature drops below a preset value. Connection for recirculating air The connection for recirculating air can be used e.g. for conveying fireplace heat to other rooms, a feature that saves electricity in that the ventilation unit s air heater then consumes less power. Correspondingly in the summer, cooling energy from an air-to-air heat pump can be transferred to other parts of the home. 2
Control System General The ventilation unit is controlled from the Premium control panel, which is standard equipment and from which you can also read and change settings. You can also select three different fan speeds from a Premium cooker hood. Control from a Premium control panel A Premium control panel can be installed at an optional location, recessed in a junction box or surface mounted on the wall. It can be located near the ventilation unit or somewhere else, and then must be connected to the unit via a 20 metre long modular cable. An extra control panel can also be connected, if it is desirable to control the ventilation unit from several places. Selectable functions Application. The unit can be started and stopped. Fan speed. The fans inside the unit can be controlled to operate at five different speeds. The display indicates the Away mode when the fans run on their lowest speed and indicates the Home mode when the fans are running at normal speed. The speed of the supply air fan can deviate from that of the extract air fan and the fans can be controlled from the control panel. Timer. The 24-hour/weekly timer has four programs. You can set the desired times if you want the unit to activate a desired function. The unit runs in the economical minimum speed mode at other times (Away). Functions: Home, Away, Boost, Cool. On the model with electric air reheat, you can also select the supply air temperature. Temperature. Desired temperature for the electric air heater can be set in the 13 20 C range. The reheating function can also be shut off (electric model). Negative pressure compensation. Negative pressure arises in the home when a separate cooker hood or central vacuum cleaner is used, since the extract airflow becomes higher than the supply airflow. This function compensates the negative pressure by automatically increasing the supply airflow. A signal from a contact in the cooker hood or the central vacuum cleaner is required. Summer operation. When certain limit values are met (when heat recovery isn t needed) the airflow is controlled to bypass the heat exchanger. Summer night cooling. The function starts, if certain temperature conditions are complied with. The airflow bypasses the heat exchanger, the electric air heater is switched off and control system increases the speed of the fans. The cooler air at night, for instance, is then utilised for cooling the home. The fan speed can be selected. The ventilation unit is controlled from Premium control panel. Cooling energy recovery. In the summer, when the indoor air is cooler than the outdoor air, the air is controlled to flow through the heat exchanger. Fireplace switch function. The function generates excess pressure in the home and in this way causes an updraught in the chimney, which prevents smoke from entering the room when you light the log-fire. Display of the operating speed. The operating speed is continuously shown as text on the display screen. Service reminder. The service reminder interval can be set to a period ranging between 3 12 months. Automatic functions Alarms. Indicate the need for filter change or servicing and a possible disruption in operation. Bypass path past the heat exchanger. For example, summer night cooling Overheating protection. For the motors and the electric air heater. Freeze protection. Prevents freezing in the heat exchanger. 3
Control from a Premium cooker hood Selectable functions The control panel of the cooker hood has three pushbuttons. Besides switching the cooker hood s lighting on and off, two control functions can be set as follows: Fan speed. The fans in the ventilation unit can be controlled to operate at three speeds: away/home/boost. The supply air fan can operate at a lower speed than that of the extract air fan. The period for operation in the boosted speed mode is preset to 60 minutes, after which the ventilation unit fans will decelerate to normal speed. The shut-off damper of the cooker hood. When preparing food or carrying out a similar activity, a 30, 60 or 120 minute damper-open period can be selected. Control of the cooker hood shut-off damper 30/60/120 min. indication Lighting Ventilation unit fan speed Away, home, boost Demand regulation (control) Demand control is possible with the following optional equipment: Timer. 24-hour/weekly timer with settable times, for when you want the ventilation unit fans to run at normal speed. At other times, the unit runs in the economical minimum fan speed mode. Boost timer. A manual pushbutton switch that can be installed at an optional location. The pushbutton switch can be located in a laundry room or the like, for example. Fireplace switch. A manual pushbutton switch that can be installed at an optional location. The function generates excess pressure in the home and in this way causes an updraught in the chimney, which prevents smoke from entering the room when you light the log-fire. Negative pressure compensation. When the cooker hood is in use, negative pressure arises in the home since the extract airflow becomes substantially higher than the supply airflow. This function compensates the negative pressure by automatically increasing the supply airflow. Home Away switch. Should be located close to the front door. When the button is pushed, the ventilation unit switches to operation in the Away mode and this saves energy. Presence detector. The sensor detects movement in the home and transmits a signal to the ventilation unit to increase the fan speed. This function is well-suited for use in premises not used around the clock, such as in schools, day nurseries, offices, etc. Humidity sensor. The sensor detects when the humidity rises and transmits a signal to the ventilation unit to increase the fan speed. It can be located in a sauna, a bathroom, a laundry room, etc. Carbon dioxide sensor. The sensor detects an increase in carbon dioxide and transmits a signal to the ventilation unit to increase the fan speed. It is suitable for use in rooms where the number of occupants varies. DDC control Modbus gateway 4 The control panel of the Premium cooker hood.
Optional equipment Optional equipment for the ventilation unit Premium extra control panel The extra control panel can also be installed, if it is desirable to control the ventilation unit from various places. The second contact of the panel can be used for interconnecting two panels. Premium control panel Base Adjustable feet facilitate mounting the unit directly on the floor. Mounting frame with moisture barrier The mounting frame has a moisture barrier which prevents moisture from entering the insulation in the attic joist floor and stops the air from the loft from coming down into the rooms.
