User manual APPLIED ENERGY XCELL 270 LONGLIFE DC

[. . . ] The external grilles associated with the unit must be sited at least 600mm away from the flue of a fuel burning appliance. Do not site any associated internal grille in the vicinity of excessive levels of airborne oil or grease without adequate filtration. Installation Instruction The Xcell 270 unit can be installed in two alternative ways to provide handed installation. Standard Installation Install the unit as supplied in standard configuration: 2 spigots at the topside "left" of which one spigot is for intake of fresh air from the outside, the other for intake of the stale air from the house. [. . . ] 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. The unit starts again fully automatically when the temp increases to 9°C. By pass operates based on the outside and exhaust air temperatures. By pass operation - dependent on internal and external air temperatures. When the exhaust air/room air temperature exceeds +24°C the yellow LED illuminates. The exhaust air/room air temperature is compared with the outside temperature. If the outside temperature is under +24°C, the bypass flap is opened immediately and colder outside air flows directly into the dwellings. The bypass flap remains open until the exhaust air/room air temperature falls below +24°C. If both exhaust air and outside air temperatures exceed +24°C both LED's illuminate (yellow for exhaust air and orange for outside air). In this operating condition the bypass closes preventing the dwelling from warming up further (reverse acting heat exchanger). If the outside temperature cools down again under +24°C, the orange LED switches off and the bypass flap is opened again until the exhaust air/room air temperature falls below +24°C. Defrost mode LED illuminates BLUE to indicate defrost is active. Exhaust air temp in the cell falls below +3°C (freezing up danger). There are two possible factory settings. Sequence of functions: Defrost cycle active. Outside/supply air fan switched off by a timer for 3 hours allowing only warm exhaust air to the heat exchanger. However if the exhaust temperature increases to +8°C the unit switches on again to heat recovery. (This option is factory installed to units without bypass). (This option is only on units with bypass). Sequence of functions: In dwellings with room air dependent fire places the equipment is factory installed in such a way that the external supply air fan does not switch off, but opens the bypass flap allowing outside air directly into the living spaces.
