BMS500-AAM027-1CSXRD

Outdoor unit

One compressor for the whole house. It supplies up to 4 heads.

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.

05 · Deep cold

At −15 °C, it still delivers 70 % of its rated capacity.

Tap a temperature: capacity, efficiency and the cost of one hour of heating.

06 · The bill

At every temperature, cheaper than baseboards.

Cost of one hour at full output, for the same heat delivered. Hydro-Québec Rate D, second tier: 11.142 ¢/kWh.

07 · Efficiency

11 · 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: 21,600 BTU/h at −8 °C, 18,900 at −15 °C.

How many heads can I connect?

Up to 4 on this outdoor unit. This product is configured for 2 heads.

Is it ENERGY STAR certified?

Yes, cold climate, ID 3554586.

Down to what temperature does it heat?

Down to −25 °C.

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. AirGreen extended warranty: possible.
