BMS500-AAM027-1CSXRC

Outdoor unit

One compressor for the whole house. It supplies up to 3 heads and modulates from 8,400 to 22,600 BTU/h depending on what the rooms call for (NEEP).

03 · How it works

Turn rooms on and off. Watch the power being shared.

One outdoor unit supplies every head: when several rooms call at once, they share its capacity. Pick an outdoor temperature.

04 · My plan

Tell us your rooms. We tell you if this size is enough.

Pick the number of rooms and their size. The estimate targets a −15 °C day; it is a guide, the real calculation is done room by room at your home.

The capacity at −8 °C comes from Hydro-Québec’s list of October 1, 2026. $50 per 1,000 BTU/h is the rate for ENERGY STAR heat pumps (guide v1.10).

Set for this system (AHRI 207760024). Another head combination (ducted, console) can change the AHRI number, and so the amount.
Cap: the grant never exceeds 100 % of the purchase and installation cost before taxes.
9 months after installation to apply; +5 % when two measures are in the same request.

19 · Questions

What people ask us about multi-zone systems.

Can I heat one room and cool another at the same time?

No. On a multi-zone system like this one, every head works in the same mode, heating or cooling. Each room still keeps its own set temperature.

What happens when every room calls for heat?

They share the outdoor unit’s capacity: 21,000 BTU/h at −8 °C, 19,000 at −15 °C.

How many heads can I connect?

Up to 3 on this outdoor unit. This product is configured for 2 heads.

Can I mix head sizes?

Yes. The “Zones” menu offers 6 combinations, from 9 + 9 to 18 + 18 (in thousands of BTU). Each head is sized for its room.

How much is the LogisVert grant?

$1,050 according to Hydro-Québec’s list of October 1, 2026. The grant never exceeds 100 % of the cost before taxes; apply within 9 months of installation.

Is it ENERGY STAR certified?

Yes, ID 2450897.

Down to what temperature does it heat?

Down to −25 °C.

Is it noisy?

Indoors, the reference head goes down to 28 dB(A). Outdoors, 63 dB(A): we place the unit away from bedroom windows.

Why a multi-zone instead of several wall units?

One outdoor unit on the wall and one circuit. In return, the rooms share the capacity, and if the outdoor unit stops, every zone stops.

What does the warranty cover?

Our sheet lists 10 years on the compressor and 10 years on parts; labour is not included by the manufacturer. AirGreen extended warranty: possible.
