Choosing the correct size HR for your home is easy, all you
need to know is the square footage.
If your home is up to:
2300 Sq. Ft. you need a HR100V
3400 Sq. Ft. you need a HR160H
5000 Sq. Ft. you need a HR220H
Choosing the Right Size HR
S&P’s HRV System
Duotrol
TM
Systems: Selects ventilation modes (OFF, CONT or INTER), and adjusts the
continuous airow rates: Increasing (+)/Decreasing (-).
Motors(2): Designed with high performance and reliability, they are maintenance free for comfort
and peace of mind.
Synthetic Filters: Capture the largest particles & protect the heat recovery core from potential
obstruction by these particles.
Heat Recovery Core: A polypropylene cross-ow type, it is designed to transfer the heat
between the exhaust & supply air streams without allowing any contamination or mixing of the
streams. This maximizes the efciency and improves indoor air quality.
Condensate Drain Pan & Drainage Hose: Captures the water that accumulates during the heat
transfer and defrost sequence in the fall, winter & early spring seasons. Drain hose is connected
to the drain pan and serves as drainage for the accumulated water. It is normal during summer
months to nd no condensation in drain pan or in drainage hose.
Automatic Defrost Sequence: The defrost sequence is electronically controlled by measuring
the temperature of the incoming outdoor air. The sequence is activated at 23°F (-5°C) with a ve
minute duration, then returns to normal operation for 25 minutes. This keeps the heat recovery
core from ice build-ups or freezing.
Defrost sequence: Supply fan shuts down, and the exhaust fan speed increases depending on
the outside air temperature.
