It connects at 240\/208 V single-phase, 2-wire; a 3-wire connection is also possible for 120–208\/240 V with accessories. Its blower is driven directly by a 1 HP four-speed PSC motor.\u003c\/p\u003e\n\u003cp\u003eDettson publishes two airflow figures for this model, measured at 0.5 in w.c.: 1,275 CFM in heating, at the medium-low speed set at the factory, and 2,030 CFM at maximum. A higher speed is generally used for cooling, and Dettson allows an air conditioner or heat pump coil of up to 5 tons on this model, on the supply or return side.\u003c\/p\u003e\n\u003ch3\u003eWhich home it suits\u003c\/h3\u003e\n\u003cp\u003eTake a multi-storey house on the \u003cstrong\u003eSouth Shore\u003c\/strong\u003e, heated by an old furnace and without central air conditioning. The owners want to replace the furnace now and add an air conditioner later. The SUP27-A240D20 fits that plan: it heats with its elements in winter and, once the coil is installed, distributes cooled air through the same ductwork. The 27 kW size itself is confirmed by assessing the heating needs, not by floor area alone.\u003c\/p\u003e\n\u003cp\u003eIn terms of space, it is 36 1\/2 in high and 22 in deep, weighs 105 lb and is approved for zero clearance. It installs in upflow (factory configuration), downflow, horizontal to the left or right, or suspended. For downflow on a combustible floor, it sits on the DFB-SUP base.\u003c\/p\u003e\n\u003ch3\u003eElectrical and heat pump: the manufacturer’s rules\u003c\/h3\u003e\n\u003cp\u003eAt 27 kW, the supply goes through two terminal blocks: a breaker of no more than 60 A for block 1 and 90 A for block 2 at 240 V (50 A and 80 A at 208 V). The published total current is 119.5 A at 240 V. If a heat pump is added, Dettson prohibits running the elements and the heat pump at the same time, as this would cause overheating: a non-simultaneous system is required, and the manufacturer offers the K03081 interface kit.\u003c\/p\u003e\n\u003ch3\u003eWhat AirGreen does\u003c\/h3\u003e\n\u003cp\u003eA family business established in \u003cstrong\u003eMontreal\u003c\/strong\u003e for more than fifteen years, AirGreen holds RBQ licence 5645-9605-01 for ventilation, refrigeration and electrical work.
