OOTING EQUENCE
The unit booting sequence is similar to a personnal computer boot sequence. Each time the unit is plugged after being unplugged, or
after a power failure, the unit will perform a booting sequence before starting to operate.
During the booting sequence, the integrated defrost control LED (2 in illustration below) will be OFF for 3 seconds, and then will turn
RED for the rest of the booting sequence (approximately 15 seconds). During this RED light phase, the unit is checking and resetting
the motorized damper position. Once the motorized damper position completely set, the booting sequence is done; the color of the
LED will show on which defrost cycle the unit is set.
NOTE: No command will be taken until the unit is fully booted.
If a problem occurs during the unit operation, its integrated control LED (2) will blink. The color of the blinking light depends on the
type of error detected. Refer to Section 7 Troubleshooting on last pages for further details.

EFROST YCLES
Five seconds after the booting sequence is done, the LED (2) will light and stay lit to show in which
defrost cycle the unit is set. Use the push button (1) to change the defrost cycle of the unit (see table
below).

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.
According to your need, there are 3 defrost cycles available:
STANDARD: This is the factory set defrost cycle, which is the most commonly used to suit normal weather conditions. 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 -17 °F [–27 °C] 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. For example,
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.
