When operating in the economy mode the outdoor fan speed is reduced back to approximately 70% of the
full operating speed. This function is designed to provide reduced power usage from the outdoor fan/s
and provide reduced noise operation during low load conditions. If the system monitors safety functions
being activated that requires maximum fan speed the control will raise the outdoor fan speed to 100% until
the safety issue has passed then it will resume economy operation.
NOTE: Outdoor fan economy operation is available as a factory default setting it can be disabled from
system the system set-up (please refer to your dealer to disable this function).

The outdoor fan motor/s is controlled via a state of the art speed control system. During operation the
indoor coil, outdoor coil, air and ambient temperatures are monitored to determine the best fan speed
operation. From these monitored temperatures the controller will change the outdoor fan speed to the
lowest setting while continuing to maintain optimum performance. The advantage of this is reduced power
consumption and lower outdoor noise levels. If required the control system will shut down the outdoor
fan/s from time to time, even while the outdoor unit (compressor) is operating this is part of the optimum
performance control and is not abnormal.

During cooling operation if the control system senses if the indoor coil is below 0°C and the system has
been operating for a specific time period the compressor will stop and not resume until the indoor coil
temperature has risen above 7°C. During this period the indoor fan will operate at low speed and the
controller will display RESET to acknowledge the freeze protection has been activated. This RESET will
need to be cleared after the system has resumed normal operation.

Zoning operation is a common function required by most ducted reverse cycle system as it provides a
means of flexible whole of home conditioning while reducing unit size and running costs. Your BONAIRE
Ducted Reverse Cycle system incorporates zoning control, up to four individual zones, built into the indoor
control unit. Not only does this provide flexible system operation but it allows simple and convenient zone
control directly from your Ultimate RF Handset or wall mounted Premium control.
NOTE: Zone motors and zoning fitment is a field supplied option (please refer to your dealer regarding the
setup and availability of zoning for your system).

EATING
In climates where the outdoor minimum temperatures falls outside the designed operating range of the
reverse cycle system you may require BOOST or supplementary heating (field supplied). If installed, your
unit can control the BOOST heating operation to assist in maintaining maximum heating performance.
When the system monitors the indoor temperature is 2 or more degrees below the SET TEMP, and
heating operation is called for, it will initiate the BOOST heating relay and start the indoor fan on high
speed, if not already on high. The unit will maintain the BOOST heating until the room temperature is
equal to the SET TEMP at which point BOOST will be switched off and the system will return to normal
heating operation. If the system initiates a defrost cycle, BOOST heating will be activated the indoor fan
will remain on and with the BOOST heaters while defrosting is being carried out.
NOTES: 1) If the system is turned OFF from the controller while BOOST heating is operating the indoor
fan will remain on for an additional 2 minutes to dissipate the residual heat in the heaters, to avoid any
safety trips. 2) BOOST heating is an installer settable function and is disabled as a factory default.
