LR7 Wall Controller

06. 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, if this option is selected.
2
Dual/Triple Wall Control Operation (Optional)
Up to three wall controllers can be installed on one system. This is particularly
useful on larger buildings, where you can have up to three wall controllers in
different locations. All connected controllers will mimic any adjustment made
in one controller (restrictions apply).
3
Room Temperature Display with One Touch
Press the
or
buttons and the set temperature display will change to
show the room temperature for 10 seconds.
4
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 system detects this frost build up and
will automatically activate the defrost mode.
The defrost mode is displayed on the wall controller by flashing the
DEFROST
indicator every 10 seconds.
5
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.
6
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.
7
Self Diagnosis
In the unlikely event that a fault develops with the air conditioner the system
will detect a fault and display the relevant fault code on the wall controller.
NOTE
Some applications may require cleaning of the filter at more regular intervals.
