4.3 SPEED AND DEFROST SETTINGS FOR AVS E15 ECM ERV, AVS E15 ECM HRV, 90H-V ECM ERV AND
90H-V ECM HRV UNITS
The special design of AVS E15 ECM ERV, AVS E15 ECM HRV, 90H-V ECM ERV and 90H-V ECM HRV units offers 4 speed ranges to
better meet to different ventilation needs.
Refer to the table below to choose the right speed range
according to the size of the house:
These units are factory set to normal defrost. In cold region (outdoor
temperature -27°C [-17°F] and lower), it may be necessary to setup extended
defrost.
NOTE: These CFM values are
approximate, they may vary
according to the installation
static pressure.
