type of error detected. Refer to Section 12 Troubleshooting on pages 19 and 20 for further details.
5.1.1 B S
OOT EQUENCE
The unit boot 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 30-second booting sequence before starting to operate. During the booting sequence,
the integrated control LED will light GREEN (unit set in normal defrost) or AMBER (unit set in extended defrost) for 5 seconds, and
then will shut off for 2 seconds. After that, the LED will light RED for the rest of the booting sequence. During this RED light phase,
the unit is checking and resetting the motorized damper position. Once the motorized damper position completely set, the RED
light turns off and the booting sequence is done.
NOTE: No command will be taken until the unit is fully booted.
5.1.2 S E
ETTING XTENDED
The unit is factory set to normal defrost. In cold region, it may be necessary to setup extended defrost. During
the first 5 seconds of booting sequence, while the integrated control LED is GREEN, press on push button until
the LED turns AMBER (about 3 seconds).
5.2 E C
LECTRICAL ONNECTION TO
For more convenience, this unit can also be controlled using an optional main wall control.
Always disconnect the unit before making any connections. Failure in disconnecting power could result in electrical
shock or damage of the wall control or electronic module inside the unit.
Never install more than one optional main wall control per unit. Make sure that the wires do not short-circuit
between themselves or by touching any other components on the wall control. Avoid poor wiring connections. To
reduce electrical interference (noise) potential, do not run wall control wiring next to control contactors or near
light dimming circuits, electrical motors, dwelling/building power or lighting wiring, or power distribution panel.
