3.4 SETTING EXTENDED DEFROST FOR S10 ERV, S10C ERV, 70E AND 70EC UNITS
These units are factory set to normal defrost. In cold region (outside temperature -27°C
[-17°F] and lower), it may be necessary to setup extended defrost. During the first
3 seconds of booting sequence, the integrated control LED shows the current defrost
mode (refer to table at right).
LED COLOR DEFROST MODE
GREEN NORMAL
AMBER EXTENDED*
Within the first 3 seconds of booting sequence, press on push button until the LED starts to blink, then release the push button; the
LED will blink AMBER 5 times. After that, the LED will shut off, then turn RED (the unit returns in its booting sequence).
NOTE: There is a 15-minute delay for the new defrost cycle choice to be kept in memory; if a power failure occurs during this time
delay, when the power returns, the unit resume to its previous setting.
3.2 S10 ERVPLUS, S10N ERVPLUS, 70E+ AND 70EN+ UNITS INTEGRATED DEFROST CONTROL
After the booting sequence is done, the LED (1) will light and stay lit to show in which defrost
cycle the unit is set. Use the push button (2) to change the defrost cycle of the unit (see table

LED COLOR DEFROST CYCLE
GREEN STANDARD
RED PLUS
AMBER DISCRETION
According to your needs, there are 3 defrost cycles available:
STANDARD: This is the factory set defrost cycle. Being the most energy recovery efficient defrost cycle available on this unit,
STANDARD is used to achieve HVI and ENERGY STAR
®
listed performance. When needed, the unit will perform
defrost cycle on high speed.
PLUS: This mode has been created for people who live in cold region (outside temperature -27°C [-17°F] and lower). This
setting makes the unit perform defrost cycle on high speed for a longer period of time.
DISCRETION: When needed, the defrost cycle will be performed on the same speed than the unit ventilation speed. This means
that if the unit is set on high speed, the defrost cycle will be done on high speed, but if the unit is set on low speed,
the defrost cycle will be done on low speed.
*Due to their unique design, the S10c ERV and 70Ec models are programmed to defrost on a regular basis, no matter the outdoor
temperature, only when set in extended defrost.
