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 Troubleshooting on page 15 for
further details.
Setting extended defrost
These units are factory set to normal defrost. In cold region
(outside temperature - 17_F [- 27_C] and lower), it may be
necessary to setup extended defrost. During the first 2 seconds of
booting sequence, while the integrated control LED is GREEN,
press on push button for 3 seconds to set the unit in extended
defrost; the LED will blink AMBER to show the unit is in
extended defrost mode. After that, the LED will shut off, then light
RED (the unit returns in its booting sequence).
Electrical connection to main controls
For more convenience, this unit can also be controlled using an
optional main wall control.
NOTES:
1. IMPORTANT: The integrated control must be turned
OFF to use an optional main control.
2. If an optional auxiliary control is used, if activated, this aux-
iliary control will override the optional main control.
WARNING
!
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury
or death.
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.
CAUTION
!
PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in property damage.
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.

Use the terminal connector included in the installation kit to
perform the electrical connection for main and optional wall
controls. Check if all wires are correctly inserted in their
corresponding holes in the terminal block. (A wire is correctly
inserted when its orange receptacle is lower than another one
without wire. See Fig. 21, wire A is correctly inserted, but wire B is
not.)
