ADVANCE FEATURES
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.
2
Dual Wall Control Operation ( Optional )
Two wall controls 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, Page 23 ).
3
Room Temp Display with One Touch
Simply press SELECT UP or DOWN arrow button and the set temperature
display will change to show the room temperature for 3 seconds.
Note: When zones are fi tted, the temperature displayed will depend on which sensor
has been selected by the wall controller ( See Zone Controller Functions, Page 22 ).
4
Integrated Zoning ( Optional )
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 fl ashing the “HEAT”
symbol 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
fl ow starts, thus preventing cold drafts. The hot start feature also activates itself
when the system fi nishes defrosting.
7
Filter Clean Light
The microprocessor monitors the accumulated run time of the air conditioner
and after a preset number of hours has passed, the “FILTER” light will fl ash,
indicating it’s time to check if fi lter needs cleaning.
(See Maintenance Sec, page 28).
8
Self Diagnosis
In the unlikely event that a fault develops with the air conditioner the
microprocessor will diagnose the fault (where possible) and display a fault code
on the wall controller. (See Trouble shooting, page 29)
