1
Auto-Restart After Power Failure
Should a power failure occur whilst the air conditioner is running, the wall
controller will restart the air conditioner in the same mode when the power is
restored, if this option is selected.
2
Dual Wall Control Operation (Optional)
Up to two wall controllers can be installed on one system. This is particularly
useful on two storey houses , where you can have one control upstairs and one
control downstairs or having the second wall controller in the master bedroom
for improved temperature control. See Dual Wall control Operation for more
info on Page
20.
3
Room Temperature Display with One Touch
Press the
or
Buttons and the set temperature display will change to
show the room temperature for 3
seconds.
Note:
When zones are fitted, the temperature displayed will depend on which sensor has
been selected by the wall controller ( See Zone Controller Functions, Page 19 ).
4
Integrated Zoning
The integrated zoning system has a unique feature where it can select which
remote temperature sensor to use depending on which zones are selected. One
example is on a two-storey house and you only have the downstairs zone on,
the zone control will select the downstairs sensor to control the temperature,
thus ensuring perfect comfort in the area occupied.
5
Auto Defrost Function (Heating Mode)
At certain outdoor conditions (low temperature) there may be a build up of
frost on the outdoor heat exchanger. This gradual build up of frost reduces the
performance of the air conditioner. The microprocessor detects this frost build
up and will automatically activate the defrost mode.
The defrost mode is displayed on the wall controller by flashing the
HEAT
indicator every 10 seconds.
6
Hot Start Function (Heating Mode)
When the air conditioner starts in heating mode, the indoor fan is delayed for a
short period of time, this allows the heat exchanger to warm up before the air
flow starts, thus minimising cold drafts. The hot start feature also activates itself
when the system finishes defrosting.
7
Filter Clean Light
The system monitors the accumulated run time of the air conditioner and after
a preset number of hours have expired, the
FILTER
indicator will flash, indicating
it’s time to check if filter requires cleaning.
8
Self Diagnosis
In the unlikely event that a fault develops with the air conditioner the
microprocessor will detect a fault and display the relevant fault code on the wall
controller. See Troubleshooting on Page 23.
NOTE
Some applications may require cleaning of the filter at more regular intervals.
