Inspection hatch Sound attenuators inlet/extract Fresh air intake Discharge extract air Air inlet/inlet diffusers Extract/extract louvers Duct from cookerhood, (Ø125/ only for VR 400 DCV/B) Flexible ducting Spiro ducting Condensation-/ heat insulation, see separate chapter 12. [. . . ] Total insulation thickness must be at least 100 mm. Make sure that all joints are covered with insulation, and tape well. Using another kind of duct system you should follow the enclosed instruction. Note: Even if the cookerhood is connected to the unit, a separate extract louver must be installed in the kitchen. Extract louvers can be ceiling or wall mounted. Inlet diffuser should be mounted in the ceiling. Make sure that the air stream from inlet diffusers has a free passage. Air stream from inlet diffuser mounted on the wall (where the ceiling is horisontal), must have throw length, so that the air is supplied to the room alongside the ceiling. Air supply through extract louvers will ensure an air stream with throw length, and extract louvers can therefore be used as inlet diffusers when mounted in the wall close to the ceiling. Use frames to ease the removing of diffusers for cleaning. cable from the cookerhood to connected as shown in shown in fig. Separate controller (4) The VR 400 DCV/B & VR 700 DCV have control panel integrated, but can also be controlled from one or more remote control panels, type CD. Extension cable with plugs (12V) to be installed between separate control panel and the unit (3), alternatively between terminal blocks (5) in control panel and unit marked 12V, GND, Hi and Lo inside the unit (see wiring 2 diagram). Use 4x0, 22 or 0, 5 mm cable when connecting between terminal blocks. When more than one controller is installed, use one or more double inlet plugs in the plug on the unit as necessary. 10A) The unit is provided with several digital inlets for overrunning of normal operation, see 1-7 in wiring diagram, . inlets to be connected to NO (normally open) , potensial free contacts. Contacts to DI5 and DI6 to be of type press buttons with automatic return. Pressure guard: If unit is to be provided with pressure guard for compensation of under pressure caused by separate ventilator, fire place etc. Home/leave: This function is especially meant for summer houses. [. . . ] Duct Cooler (for cooled water) Cooled water battery to be installed in the supply air duct (for installation of battery, see separate instructions provided with the battery). When installed, the cooled water battery will be operated in sequence with the hot water battery, alternatively with the electrical re-heater. Example of valve motor: Regin type MVT57 Example of valve: Regin type VST (2-way valve) or VMT (3-way valve) Example of transformer: Systemair 24V/PSS48 The units has to be configured for operation with cooled water battery, see item 7. 1 in separate instructions , “Operation service menu”.
