When power is first applied to the Wall Control there are 3 possible responses depending on what
is connected to the Wall Control.
When the Wall Control is connected directly to an ICON cooler without any Hubs,
either on a single cooler installation or during individual cooler commissioning on a
multiple cooler installation, the Wall Control will display (Fig. 8).
Press and hold the button until the word disappears from the
display. This will take approximately 7 seconds. This transfers ICON specific
operating requirements to the Wall Control. To complete this transfer see
“CHANGING SPEED TABLE FOR COOLERS” below.
When one TBA cooler is connected the Wall Control will display the OFF state.
When a Hub (Kit #105949) is connected the Wall Control will display the OFF
state.
When one or more Smart Hubs (Kit #111070) are connected the Wall Control will
display the identity of every Smart Hub as it is detected by the Wall Control during
initialization (Fig. 9). The Wall Control starts at Hub 0 and can count up to
Hub 9, ie. a total of 10 hubs.
When the Wall Control has completed it's initialising function and the last Hub is displayed, press
the button to accept. The Wall Control now enters the OFF state and will display just the day

Humidity Mode 1 and Mode 2
The default mode provides a maximum Humidity Limit per the set point within the Wall
Control. In this mode the AUTO control function will respond to the temperature sensor to achieve
comfort conditions in the building according to the temperature set point in the Wall Control. However
the pump will stop (and therefore no moisture is added) when the room humidity rises to the humidity
set point in the Wall Control.
The alternative mode allows the cooler to attempt to satisfy both temperature and humidity,
with humidity over-riding temperature when the temperature is satisfied but the humidity is not.
The choice of which mode to use is made by changing parameter B4. See instructions below. In the
MANUAL mode no humidity control is enabled.
Disconnect power to the cooler, then reconnect power. Then, while the IWC10 is in the OFF state,
press and hold the button for 3 seconds and continue to hold whilst you press the button.

Programming Wall Control
When full temperature and humidity control is selected via parameter B4, the cooler will
function as follows in AUTO: When the room temperature falls below the temperature
set point the fan and pump will normally stop. But if the room humidity is below the
humidity set point, they will remain ON to add moisture to the room to satisfy the
humidity requirement. The function of the fan and pump under this condition is shown in
Fig. 22.
The external humidity and temperature sensor requires air moving freely through
the sensor housing to maintain accurate readings of the temperature and humidity. The
sensor should be periodically checked to ensure that the air inlets are not clogged up by
dust. If they are, try to clear the dust away but do open the sensor housing.

REMOTE ON/OFF
This input is used to turn the cooling system ON or OFF from a remote location.
The input must be in the form of a momentary pulse (provided by the installer) for both ON and
OFF functions. Any repeated pulses received within 2 seconds of the first pulse will be ignored.
When a pulse is received during cooling system operation (whether AUTO or MANUAL) the
control will save the current state of the system and the system will enter a stand-by state and
shut down.
When the next pulse is received at Input 8, the cooling system will start up again in the same
mode in which it was last shut down.
In the event that the cooling system is re-started manually during the standby state, the next
pulse received at input 8 will shut down the system into standby mode.

However, before doing so, turn the Wall Control OFF. You will notice a number flashing at the
bottom of the screen (Fig 31). This number indicates the cause of the fault. See “Service Guide
CMPD” for fault codes.
Please write this number down, then push the button to turn the cooler back on. If after a short
time is again shown on the display, turn the Wall Control OFF and check if the flashing
number is the same. If so check the following possible problems. However, we do suggest that any
checks be carried out by an authorised dealer or service agent.
Check that the water supply tap to the cooler is turned on.
Check that your local water supply is on.
If your cooler is fitted with a drain valve, check that the drain is not blocked.
Check to ensure that the temperature and humidity sensor is plugged in.
Check the interconnecting cable for faults.
If the problem continues contact your Dealer or Service Agent. You will need to quote the flashing
number that you wrote down.

SERVICE MODE - MULTIPLE COOLER INSTALLATION
This section ONLY applies to any new installations commissioned since January 2006, in
which IWC05’s (part no. 111087) and Smart-Hubs (part no. 111070) are installed. Installations
prior to that date do NOT have any fault indicating features when multiple Breezair coolers
are connected to original hubs.
Identification labels “IWC05” and “Smart-Hub” are attached to the new devices.
SERVICE
!
When a fault occurs in any cooler, the word appears on the Wall Control display (Fig.
32). The system will continue normal operation.
In cases where Smart-Hub kits are installed (and only in such cases) the fault location can be
viewed by either pressing the button or switching the wall control OFF (Fig. 33). The fault
location display shows the Hub number (0 - 9) and the cooler number (1 - 5) on that hub.
If more than one fault exists, pressing the or buttons shows other fault locations.
Fault codes that identify the nature of the fault will not be shown; however the nature of the
fault can be found at the faulty cooler(s) on their CPMD Electronic Module(s).
Note
DRAIN MODE
Pressing the and buttons at the same time will open the drain valve and empty the water
in the tank. The Wall Control will display on the screen. Draining the water will leave the tank
clean and dry until it is next used. The drain valve will remain open until the cooler is re-started.
POWER FAILURES
Momentary power failures (less than 1
second) may restart automatically when power is restored.
Any power failure of any duration will shut down the air cooling system and will require manual re-
start. Power failure means a complete loss of mains power to the air cooling system. It may be
caused by external factors over which you have no control, or it may be caused during the
commissioning procedure by the deliberate action of the technician.
Whatever caused the power failure, and whatever mode the cooling system is set to (MANUAL or
AUTO), the system will require manual restarting.
EXTERNAL control mode will
resume automatically after power has been restored if the external commands are present. The
lithium battery will maintain the clock during prolonged power OFF periods.
