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.
3.1.1 ERV100SP U
During the booting sequence, the integrated defrost control LED
(1 in above illustration) 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, or if the unit turns in Protection Mode, its LED (1) will blink. The color and the blinking
pattern depend on the type of error detected, or if the unit is in Protection Mode.
Refer to the sticker on the unit and Section 9 Troubleshooting on page 22 for further details.
