8. Key features
FeatureDescription
Range overviewHigh Static Three Phase R32 ducted range available in four models from 10.0 kW to 15.5 kW, with cooling operation up to 50°C, demand-response compatibility and zone-system capability for larger homes.
Zone controlAllows selected areas to be conditioned independently through a compatible zoning system.
Auto restartRestarts in the previous operating mode after temporary power interruption.
Auto changeoverAutomatically selects heating or cooling according to setpoint and room temperature.
Blue Fin heat exchangerImproves outdoor heat-exchanger corrosion resistance, particularly in coastal environments.
Connectable distributing ductSupports field-supplied branch ducts for airflow distribution.
Connectable fresh-air ductAllows introduction of outdoor air into the occupied space.
Demand responseCompatible with approved air-conditioning demand-response programs.
Economy modeLimits maximum current and reduces power consumption.
Filter signAllows a filter reminder interval to be selected according to expected dust loading.
On/Off timerProvides a once-per-24-hour start or stop timer.
Program timerSupports ON, OFF, ON-to-OFF and OFF-to-ON schedules.
Weekly timerAllows different schedules for up to seven days.
Automatic fan speed adjustmentAutomatically changes airflow to suit room-temperature conditions.
50°C cooling operationGuaranteed cooling operation up to 50°C outdoor dry-bulb temperature.
Demo modeAllows the indoor unit to run independently for displays and showrooms.
Automatic static-pressure adjustmentAutomatically determines the optimum static-pressure setting during commissioning.
Product note: Confirm current accessory compatibility, controller combinations, seasonal-performance data and installation requirements against the latest product literature and technical manuals before specification or installation.
