It is supplied at 120–240\/208 V on three wires and uses a 1\/3 HP direct-drive PSC motor with 4 speeds. For heating, Dettson sets this motor at the factory to its high speed: 1,150 CFM at 0.5 in w.c. The published temperature rise is 60 to 80 °F at 240 V.\u003c\/p\u003e\n\u003cp\u003eLike the whole Avantage series, it switches its elements on in sequence, makes them replaceable one by one and groups the continuous-fan switch, the low\/high power switch, the heat-demand indicator light and the breakers on the front panel.\u003c\/p\u003e\n\u003ch3\u003e240 V or 208 V: a difference worth knowing\u003c\/h3\u003e\n\u003cp\u003eThe output of an electric furnace with elements depends on the voltage it receives. Dettson publishes 20 kW at 240 V, but 15 kW at 208 V, or 51,256 BTU\/h. In a single-family house in \u003cstrong\u003eLaval\u003c\/strong\u003e or on the \u003cstrong\u003eNorth Shore\u003c\/strong\u003e, the supply is generally 240 V; in some \u003cstrong\u003eMontreal\u003c\/strong\u003e buildings, it is 208 V. We check the actual voltage before confirming that this size meets your needs.\u003c\/p\u003e\n\u003ch3\u003ePreparing the electrical circuit\u003c\/h3\u003e\n\u003cp\u003eAt 20 kW, the electrical connection deserves attention. Dettson calls for a 125 A maximum breaker at 240 V (100 A at 208 V) and publishes a 108.05 A ampacity at 240 V. Your electrical service must be able to take this circuit on top of the rest of the house. During the visit, we assess your panel and state it clearly in the quote.\u003c\/p\u003e\n\u003cp\u003eLooking ahead, the furnace accepts an air-conditioning or heat-pump coil of up to 3 tons, on the supply or return side. With a heat pump, the elements act as backup, never heating at the same time as the heat pump; the K03081 interface handles this Dettson rule.\u003c\/p\u003e\n\u003ch3\u003eA well-managed AirGreen installation\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.
