User manual APPLIED ENERGY XCELL 150 WIRING DETAILS

[. . . ] 2 spigots at the topside "right" of which one spigot is for discharge of the stale air to the outside, the other spigot for the heated fresh air into the house. Duct Connections. Duct dimensions are to match the nominal 150 mm spigot. When designing the system, reduce to smaller diameter ducts by using a 3-way splitter or efficiency will be reduced. Use only rigid ducting to connect directly to the system. [. . . ] Electrical Connection Diagram Ensure the mains electrical supply is switched off before commencing installation. Power supply for the Xcell 270 unit will be 220-240V / 50Hz. The appliance is Class 1 and it must therefore be earthed Wiring to the appliance must be via a fused and switched connection unit incorporating a double pole isolating switch with 3mm contact separation. The Xcell 270 unit should be connected as the electrical connection diagrams below: The Xcell 270 unit should be wired accordingly to obtain the desired speed: From unit Mains Yellow / Green Brown Grey Black L Blue LOW SPEED N From unit Mains Yellow / Green Brown Grey Black L LINK Blue N MED SPEED From unit Mains Yellow / Green Brown Grey Black L LINK Blue HIGH SPEED N The Xcell 270 unit can also be wired through either one of two three speed selector switches as detailed below: ARRANGEMENT OF THE LIGHT EMITTING DIODES (LED) 7. Red LED - Motor 1 or 2 failure, unit will shut down 6. Green LED flashing ­ Exhaust air filter warning 5. Green LED flashing ­ Incoming air filter warning 4. Yellow LED - Exhaust air temperature >+24oC 2. Orange LED - Outside air temperature >+24oC 1. Red LED - Frost protection active, unit will shut down Protective device against the freezing of heating or plumbing. RED LED illuminates when the exhaust temperature sensor falls below 8°C and switches the unit off automatically. External/supply air LED illuminates green (constant) Motor 1 external/supply air runs at zero resistance (i. e. Exhaust/waste air LED illuminates green (constant) Motor 2 exhaust/waste air runs at zero resistance (i. e. Filter monitoring function This is determined by the power input of the pressure controlled DC motors. If the air resistance (Pa) increases due to dirty filters to a level greater than the programmed threshold the two green LED's flash. Fan motor failure due to blocked rotor or fuse failure LED illuminates red (constant). The unit will shut down after 75 seconds. Only when the problem is repaired and the power reconnected to the unit, will the Red LED go out. The Xcell unit is supplied with 3 factory set speed settings as below: · Speed 1 ­ Night time setting (or when the building is unoccupied) ­ 110m3/h · Speed 2 ­ Normal setting - 175m3/h · Speed 3 ­ Boost setting - 275m3/h Each of these three settings can be adjusted by means of dip-switches mounted on an internal circuit board (as below) to give performance appropriate for room size. Access to this circuit board is through the removable mounting plate situated on the right hand side of the unit. Ensure that the electrical supply is disconnected to the unit before attempting to access the circuit board or adjust dip-switch position. Intake and extract settings can be set independently of each other. [. . . ] Make sure not to damage the seating-slides. · Clean the heat exchanger by soaking the unit for a minimum of two hours in warm water with washing up liquid. · Rinse the unit with water and wait until all water has dripped out of the cleaned unit. Any residual moisture will evaporate during use. [. . . ]
