Residential HRV/ERV
22
If low speed is insucient and high speed is required to satisfy ventilation rate, connect a
jumper between terminal connections 3 and 4, and place a switched line between terminal
connections 1 and 4. This sets the ventilation speed to high.
Enabling High Speed
With either wiring method above, EvacMAX™ provides demand-based high speed operation
for maximum ventilation. This disables frost control, and should only be used for short
periods of time, such as boosting ventilation for bathroom exhaust. To enable EvacMAX™,
place a switched line between terminal connections 1 and 5. Finally, unplug the HRV and
then plug it back in while holding down the black button on the control panel. The Aldes
20/40/60 Minute Timer (P/N 611228) is recommended for controlling EvacMAX™.
Note: EvacMAX is not available on models ending in -NOVO.
