3 Technical description Design The dampers are available as standard in the circular version in dimensions mm. The rectangular variants are designed as louver dampers and are obtainable in most sizes available on the market up to size 1600 x 700 mm. The circular variant is also available in an insulated version. The circular sizes have a damper that can shut off the airflow to tightness class 4; the rectangular sizes are to tightness class 3, degree of protection IP30. is supplied completely mounted and configured for the relevant function. Figure 1., uninsulated circular version. Functions for zone applications Pressure regulation in supply and extract air zones respectively. Flow regulation of the slave unit or constant flow. Optimisation of zone damper position in respect to room product damper position. Slave flow regulation sums up several units via Super WISE and Modbus. Emergency settings open or closed via Modbus communication. Circuit closure via external contact function. Wireless hand-held terminal for making checks and setting values. Figure 2., insulated version. Materials and finish The sheet-metal parts are made of galvanized sheet steel. All the plastic parts are completely free of PVC. PC plastic is the main material used. Commissioning is normally pre-set from the factory, therefore no adjustment is necessary. Follow-up programming can be carried out using the TUNE Control hand-held terminal, via Modbus RTU or Super WISE In the systems with Super WISE, the network needed for communication with subordinate items of equipment will be automatically identified. Maintenance Dirty products must be cleaned by wiping with a cloth to remove dust. NOTE: Do not use a vacuum. Declarations Building material declaration is available for download from Figure 3. for rectangular ducts. 3

4 Slave unit SLAVE Zone and SLAVE MSFE The slave unit is a flow- or optimisation regulating unit, which is totally controlled by. The slave unit is only intended for extract air and is placed in the exhaust system within the same zone. The airflow through the slave unit may deviate from the airflow of the master unit by a programmable offset-value in l/s. Slave unit with MSFE functionality (SLAVE MSFE) is a separate accessory than ordinary slave damper (SLAVE Zone). SLAVE Zone - functions: Static non-clogging, airflow measurement Position-independent Shut-off-capable damper to tightness class 4, rectangular version to tightness class 3 Insulated version (optional) Rectangular version as an option, rectangular dampers should always be mounted with their shafts horizontal. TUNE Control TUNE Control is a hand-held terminal for. TUNE Control is used for control and changing of regulation variables in. The hand held terminal can be connected to the CON- TROL Zone directly via radio link. It can also be connected with a cord. TUNE Control - functions: Wireless communication 433 MHz according to EN Range ca 30 m Battery life (4 type LR03 batteries) approx. 2 years Project planning Zone applications See separate documentation, "WISE Project Manual", available to download on Swegon's sales team can also provide with standard zone templates with detailed information regarding function, flow charts and demarcation list for various contractors.

5 Balance at room level The damper PE/PS (1) is used for maintaining constant pressure in both the supply air and extract air ducts. Airflows and balance are controlled at room level. The toilet groups, if included, should be connected directly to the pressure-controlled branch duct. No Modbus communication is necessary. 2 1 (PE) Balance at zone level, mixed - transfer air and balance The damper PSFE (1) maintains constant pressure in the supply air duct. The flow is used for slave-controlling the central SLAVE Zone extract air damper (2). The damper (3) keeps the extract air duct under constant pressure so that toilet groups (4) and air registers in rooms with varied airflow can be connected to the extract air duct. The zone damper (3) open/close their damper blade to meet the airflow needs in the zones. 2 1 (PS) Figure 5. Pressure control of both the supply air and extract air ducts without slave flow. Balance at zone level - transfer air solution The damper (1) maintains constant pressure in the supply air duct. (1) measures the total airflow in the zone. The flow is used for slave-controlling the central Slave Zone extract air damper (3). The constant extract airflows, if any, within the zone are controlled by one more damper FE (4) which in this case is used as a constant-flow damper. To create balance in the zone, specify an air flow offset which corresponds to the extracted air in the constant air flow product. This value is set in the controller CON- TROL Zone. 4 (FE) (PED) 2 (SLAVE) 1 (PSFE) Figure 8. Balance at zone level, mixed - transfer air and balance.

Supply air is optimized in regards to the damper position of the room products and extract air damper is slave controlled to extract the same amount of air as is supplied through the supply air damper. It is possible to set an air flow offset. 5

6 Summation of the airflows within a zone All the zone dampers are of type. The supply air dampers, PS (1) maintain constant pressure. The DETECT Pressure sensor (2) is located 2/3 the distance out on the branch duct. The constant extract airflows within the zone are controlled by one more zone damper, FE (3). Central extract air flow, FE (4) is obtained by adding the airflows from all the supply air dampers and subtracting the constant extract airflow. This is carried out by Super WISE (5). Super WISE manages up to zones. All communication between dampers and Super WISE is conveyed with Modbus RTU. Decentralised air handling unit In this solution, which is most often used in smaller systems, the air handling unit uses sensor (5) to control the pressure in the supply air system. The room regulation is managed by the ADAPT products (3) and all extract air is balanced by the air handling unit. Constant pressure (1) must therefore be maintained in the extract air by means of CONTROL Z PED (2) if a toilet group with constant extract airflow (4) is to be connected. 3 (FE) 5 4 (FE) 1 (PS) 2 (PED) 1 1 (PS) (PS) Figure 11. Several master units for pressure control of the supply air, slave flow regulation of the extract air via Super WISE which sums up/subtracts the air flows.. Figure 12. CONTROL Z PED keeps the pressure constant in the extract air duct so that a constant airflow is always supplied to the toilet group regardless of the total extract airflow. 4 6

7 To wire the zone dampers is supplied either as default or configured for the correct function (see page 4 for alternative). When delivered as default the configuration is always set to PSFE. When the product is supplied as the default, the damper actuator and the flow signal cables are not connected. This wiring must be done at the site according to the instructions for the function desired. Connect the to 24 V AC supply voltage and protect the circuit with a max. 6 A fuse. Wire all other connections to Modbus and other components according to the wiring instructions. The controller is equipped with pluggable screw terminals, which substantially simplify the installation work. Requirements on wire cross-sectional areas See figure 13. Supply voltage with 24V AC to (1), at max. 6 A applies to 1.0 mm 2. Signal wire from Flow sensor (3) to (1) max 30 m >= 0.75 mm 2. A 4-wire with 0.75 mm 2 should be fitted between CON- TROL Zone (1) and Damper actuator (2). Electrical data The particulars apply to and SLAVE Zone only.

9 Sizing Circular design Airflow capacity The airflow capacity of the product is important for planning if airflow measurement is included in the product. Recommended maximum airflow is given at a pressure drop of 1 Pa/m in the duct. The black scale represents recommended working range between min and max flow Sound power level The diagrams for the various sizes show the total generated sound power (L Wtot db), as a function of the airflow and pressure drop across the damper. By correcting L Wtot with the correction factors specified below, the sound power levels can be obtained for each octave band (L W = L Wtot + K ok ) l/s 00 Transmitted sound Calculate the transmitted sound from according to the formula: L Wut = L Wkanal + K trans The data refers to an uninsulated and is related to the duct length of the damper.
