The \u003cstrong\u003e4-Zone Heat Pump ARCOAIRE D5CMHA | 55,000 BTU - R454B\u003c\/strong\u003e gives each its own head and set point, on a single condenser. That \u003cstrong\u003e4.5-ton\u003c\/strong\u003e \u003cstrong\u003eD5CMHAH55FAK\u003c\/strong\u003e condenser serves \u003cstrong\u003e4 zones\u003c\/strong\u003e and accepts up to 5 at most. It is built with the \u003cstrong\u003eD5FSHAH09XAK\u003c\/strong\u003e, \u003cstrong\u003eD5FSHAH12XAK\u003c\/strong\u003e, \u003cstrong\u003eD5FSHAH18XAK\u003c\/strong\u003e, \u003cstrong\u003eD5FSHAH24XAK\u003c\/strong\u003e and \u003cstrong\u003eD5FSHAH30XAK\u003c\/strong\u003e \u003cstrong\u003ewall-mounted heat pump\u003c\/strong\u003e heads.\u003c\/p\u003e\u003cp\u003eIts ratings are \u003cstrong\u003e22.3 SEER2\u003c\/strong\u003e, \u003cstrong\u003e12.0 EER2\u003c\/strong\u003e and \u003cstrong\u003e10.5 HSPF2\u003c\/strong\u003e. The system is \u003cstrong\u003eENERGY STAR\u003c\/strong\u003e certified with the \u003cstrong\u003ecold-climate designation\u003c\/strong\u003e under \u003cstrong\u003eENERGY STAR ID 3556883\u003c\/strong\u003e. The certificate still lists its capacity at \u003cstrong\u003e-30 °C\u003c\/strong\u003e, and the system qualifies for a \u003cstrong\u003e$5,640 LogisVert grant\u003c\/strong\u003e.\u003c\/p\u003e\u003ch3\u003eA home where the rooms do not share the same load\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eload calculation\u003c\/strong\u003e of a large home rarely gives four similar figures. The open ground-floor area, with its large windows and patio doors, demands a lot in winter as in summer. The primary suite, often facing the backyard, has its own solar gains. The children's bedrooms are smaller and more stable. Finally, the room above the garage behaves like a separate house. A multi-zone system lets you answer each one with a head of a different size, rather than imposing a compromise on the whole house.\u003c\/p\u003e\u003ch3\u003eThe room above the garage\u003c\/h3\u003e\u003cp\u003ePlayroom, office or guest room, the room above the garage piles up the difficulties: a floor sitting over an unheated space, often three exterior walls, and a roof right overhead. It is the coldest room in the house in January and the hottest in July, and baseboards struggle to keep up. A dedicated head changes that: it heats and cools according to its own set point, without depending on the rest of the house. We mount it on a wall from which the air covers the whole room, and during the visit we look at the floor and wall insulation, because a head cannot compensate indefinitely for a failing envelope.\u003c\/p\u003e\u003ch3\u003eFour heads chosen one by one\u003c\/h3\u003e\u003cp\u003eEach head's code indicates its size, from the D5FSHAH09XAK, the most compact, to the D5FSHAH30XAK, the largest. One possible distribution: a D5FSHAH30XAK or D5FSHAH24XAK in the open area, a D5FSHAH18XAK in the primary suite, a D5FSHAH18XAK or D5FSHAH12XAK above the garage, and a D5FSHAH09XAK or D5FSHAH12XAK in a child's bedroom. The total of the four heads must stay within the combinations the manufacturer allows for this condenser, and each head is chosen as closely as possible to avoid short cycles in the small rooms.\u003c\/p\u003e\u003ch3\u003eWhy 4.5 tons for four zones\u003c\/h3\u003e\u003cp\u003eThis size is justified when the zones are large or difficult: a heavily glazed open area, a room above the garage, a home with an older envelope. In a recent home with moderate rooms, a smaller condenser may be enough and run more often at low speed, where it is most efficient. It is the room-by-room calculation, not the total floor area, that decides; we recommend this model only when the figures justify it.\u003c\/p\u003e\u003ch3\u003eA fifth zone in reserve\u003c\/h3\u003e\u003cp\u003eThe D5CMHAH55FAK accepts a fifth head. A second child's bedroom, a finished basement or an office can be added, provided the combination of five heads remains allowed. We take this into account in choosing the first four heads and in laying out the lines.\u003c\/p\u003e\u003ch3\u003eThe published values at -8, -15 and -30 °C\u003c\/h3\u003e\u003cp\u003eThe certificate lists \u003cstrong\u003e47,000 BTU\/h at -8 °C\u003c\/strong\u003e and \u003cstrong\u003e47,000 BTU\/h at -15 °C\u003c\/strong\u003e. The two points are measured separately; we report each one as published.\u003c\/p\u003e\u003cul\u003e\u003cli\u003eCOP of 2.60 at the -8 °C point (17 °F)\u003c\/li\u003e\u003cli\u003eCOP of 2.00 at the -15 °C point (5 °F)\u003c\/li\u003e\u003cli\u003eMaximum capacity at -30 °C: 26,400 BTU\/h, COP of 1.39\u003c\/li\u003e\u003cli\u003eHeating certified down to -30 °C\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eThe published capacity stays identical at the two most common cold points, below the nominal 55,000 BTU size, as is normal in deep cold. Near -30 °C, it drops; the baseboards you keep, particularly in the room above the garage, then serve as backup. These figures come from certificate \u003cstrong\u003eAHRI 215357158\u003c\/strong\u003e, published by NEEP.\u003c\/p\u003e\u003ch3\u003eThe ratings, simply explained\u003c\/h3\u003e\u003cp\u003eThe 10.5 \u003cstrong\u003eHSPF2\u003c\/strong\u003e sums up \u003cstrong\u003eheating\u003c\/strong\u003e efficiency over the whole season, the rating that weighs most on a Quebec bill. The 22.3 \u003cstrong\u003eSEER2\u003c\/strong\u003e does the same for \u003cstrong\u003ecooling\u003c\/strong\u003e, and the 12.0 \u003cstrong\u003eEER2\u003c\/strong\u003e measures efficiency in very hot weather. \u003cstrong\u003eCOP\u003c\/strong\u003e is the most concrete: at 2.60 at -8 °C, the heat pump delivers as heat more than two and a half times the electricity it consumes, whereas an electric baseboard delivers exactly what it consumes.\u003c\/p\u003e\u003ch3\u003eSummer: the hot rooms first\u003c\/h3\u003e\u003cp\u003eIn July, the room above the garage and the glazed open area are the first to call. The \u003cstrong\u003einverter compressor\u003c\/strong\u003e speeds up to answer them, then slows down and holds the four set points at low speed, removing humidity from the air along the way. Each head's \u003cstrong\u003edehumidification\u003c\/strong\u003e mode takes over on muggy days. The four heads work in the same mode at any given time, heating or cooling, each at its own temperature. The new-generation \u003cstrong\u003eR-454B\u003c\/strong\u003e refrigerant has a global warming potential markedly lower than the fluids it replaces.\u003c\/p\u003e\u003ch3\u003eThe $5,640 LogisVert grant\u003c\/h3\u003e\u003cp\u003eThe system is listed in Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e program, with \u003cstrong\u003e$5,640\u003c\/strong\u003e for the owner of an existing home, according to the list in effect on the installation date.

The large condenser goes on a solid stand or a bracket designed for its weight, above the snow line, out of the path of snow falling from the roof and as far as possible from bedroom windows. Each head gets its refrigerant line set, communication cable and drain; the lines from the upper floor and from the room above the garage are grouped under a finishing cover, or pass through the attic when the facade does not lend itself to it. The drains flow by gravity or through a condensate pump. The condenser is connected to a properly sized \u003cstrong\u003ededicated circuit\u003c\/strong\u003e. Since R-454B is mildly flammable, each connection follows its rules, before the leak test, the vacuum, commissioning of the four zones and programming the remotes with you.\u003c\/p\u003e\u003ch3\u003eMaintenance\u003c\/h3\u003e\u003cp\u003eRinse the four filters every two weeks in season. Keep the condenser clear of snow, ice and leaves, without covering it in winter. An annual \u003cstrong\u003eHVAC maintenance\u003c\/strong\u003e visit cleans the coils and blower wheels, checks the drains and tightens the electrical connections. In winter, white vapour during defrost and a short pause in heating are normal.
