2004 SERIES - CHILLER SYSTEMS - OPERATION AND INSTALLATION MANUAL - PAGE : 3
As from May 2004 all WEBASTO air condi-
tioning units are controlled by a Digital
Display <CHILLER CONTROL> 2004
SERIES which gives access to all functions
necessary for the normal operation of the unit
and attached accessories (blowers, pumps,
etc).
All WEBASTO air conditioning units are
sea-water cooled by means of an AC sea-
water pump.
In order to start the system you only need to
press the On/Off key on the digital display.
From there on the electronic control unit
takes care of the progressive starting up of
the air conditioning components as well as it
normal functioning.
The digital display will show the present
room temperature of the cabin in which the
digital display is situated or where the main
temperature sensor is located (in case the
optional secondary temperature sensor is
used).
The WEBASTO <CHILLER CONTROL>
digital display allows access to information
and controls at three distinct levels :
Immediate Access - Level 1 :
1) Room temperature read-out in the main 4
LED display window
2) 3 small LED’s to the left indicating the
operating cycle presently active :
- Cool cycle only operation.
- Automatic cycle switching governed by
the end-users entered set-point temperature.
- Heat cycle only operation.
3) 2 set-point keys give immediate access
to the thermostatic set-points for blower-
control (“Sun” and “Snow” key).
These keys are also used to alter program-
ming values - see here-after chapter 6.
Press and hold one of the set-point selector
keys and wait until the new desired set-point
temperature is obtained. Release the set-
point key.
The display will memorize the value and
return to normal room temperature read-out
after approx. 5 seconds.
Secondary commands and info -
Level 2 :
The F/Blower key gives immediate access to
a number of secondary commands which
need to be accessed frequently for day to day
operation.
First access is to the blower speed control,
then chilled water temperature read-out, etc.
See hereafter drawing 2.1 for complete list.
Programming Commands - Level 3 :
A number of programming commands that
do not need to be accessed for day to day
operation are hidden and require a special
procedure to enable access and modification.
An access code can be enforced to avoid
accidental modification of programming val-
ues.
See Chapter 6 - Page 9.
Start-up delay :
After pushing the On/Off key the LED’s will
display <On> while initializing the system.
Push again to stop operation - the display
will briefly show <Off> before extinction.
The adequate LED to the left (heat, cool , etc)
will come on after approx. 15 seconds and
compressor operation will start after approx.
50 seconds.
The chilled water circulation pump will
come on immediately after system initializa-
tion.
