2004 SERIES - CHILLER SYSTEMS - OPERATION AND INSTALLATION MANUAL - PAGE : 3

2004 SERIES - CHILLER SYSTEMS - OPERATION AND INSTALLATION MANUAL - PAGE : 3

As from May 2004 all WEBASTO air condi­tioning 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 sea­water 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 blower­control (“Sun” and “Snow” key).
These keys are also used to alter program­ming 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 set­point 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 val­ues.

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 initializa­tion.

New features - 2004 Series :

As from June 2004 all WEBASTO air condi­tioning units are controlled by a new Digital
Display <AIR CONTROL> 2004 SERIES

2.1 - <CHILLER CONTROL> DIGITAL DISPLAY - OPERATING GUIDELINES

EDITION DATED 21ST AUGUST 2006

which gives access to all functions necessary
for the normal operation of the unit and
attached accessories (blowers, pumps, etc).

2004 Series Electronic Controls are easily
recognized by their special remobale bezels.

The new 2004 displays are backwards com­patibel with the older TCC electronic con­troller cards. In that case however the dedi­cated Blower key is not operational.

Continued features - 2000 Series :

A) Automatic blank/sleep mode -

pro­grammable time delay. Factory default : 15
minutes. While in blank/sleep mode the cycle
LED flashes discretely every 20 seconds. To
go back to normal operation push any key.

B) Calibrate all blower speed settings

in real time mode.
It is now possible to calibrate all speed set­tings (1 to 5) before actually putting the sys­tem into service.

To do so enter programming mode with set­point at 15° C.; proceed to line <6> = speed
5 (max). (see chapter 6 - page 9)
The blower will start to function as soon as
you access code <6>.

Alter the value to the right of code <6> and
the blower speed will immediately change in
real time. When satisfied go to following line
<7> = speed 4 and do the same.

Proceed until lowest speed N° 1 and go back
again to speed N° 5 if not satisfied.

When all speeds are programmed according
to need, validate by pushing on/off key
(<memo> will be displayed briefly).

Attention : Never program speeds
so low that the blower is in danger
of stopping or will not re-start at
that setting.
This will inevitably entail motor­windings burn-out and will not be
covered by the WEBASTO warran­ty.

C) Infra-Red Remote Control :

Infra-red remote control can be purchased as
an option. This remote control is based on the
standard protocols also used by TV and other
appliances. Although the WEBASTO con­trols have been chosen so as to avoid inter­ference with most TV models, the end-user
should be aware that in certain cases interfer­ence may occur with TV sets or other appli-

ances.

Generaly, it is therefore advisable to avoid
locating a WEBASTO <AIR CONTROL>
display next to other appliances using infra­red control units.

D) ACCESS CODE :

The end-user can deny access to all program
settings by introducing an access code (see
page 10 - code <b>). Blower speed and set­points always remain accessible.

Once an access code is activated, the digital
display will show <Code> if the end-user
tries to access other functions then blower
speed or set-point temperature. To gain full
access push the sun key to reach the code
value as programmed and push the F key
again to gain access to full program settings.

3 - CENTRAL BLOWER CON­TROL

The central <CHILLER CONTROL> digital
display which controls general operation of
the condensing unit(s) can also directly con­trol the blower(s) of the saloon/cabin where
the main temperature sensor is located.

This direct blower control is optional and not
all installations use this facility to control a
part of the ship’s blowers.

Blowers in the wheel-house for instance,
where the <CHILLER CONTROL> display
is located, can be directly controlled by the
TECC card. The <FAN> outlet of the TECC
controller card offers manual speed settings
and thermostatic control in the same manner
as the individual cabin controls.

This central blower control is therefore quite
distinct from the secondary Cabin Control
systems where the <AIR CONTROL> digital
display only operates the blower(s) of the
cabin where the display is situated without
any direct link to the main condensing unit.

Any blowers directly connected to the TECC
controller card will be activated after the
cycle LED comes on. However blowers will
only become active if the chilled water tem­perature is compatible with the enteredset­point.

If blower operation cannot be activated the
error code <bA11> will flash briefly and then
remain visible when accessing blower con­trol through F/Blower key.
(See also here-after list of error codes).

Blower operation will only start after a com­patibility check with the temperature of the

chilled water circuit.

Example : in <Cool> mode with a set-point
temperature of 21° C., blower operation will
only start after the temperature of the water
circuit has reached 20° C or less. This avoids
start-up of blower operation with a non com­patible water circuit temperature.

For these TECC cards it is possible to alto­gether stop blower operation by choosing the
option <0> after manual blower speed <1>.

This allows to altogether stop blower opera­tion by the main controller card during the
night for example while still continuing to
operate the chiller unit for the rest of the
ship’s air-handlers.

With the <CHILLER CONTROL>, blower
control is completely distinct from compres­sor operation :

1) Blower control will continue even if com­pressor operation is thermostatically stopped.

2) Compressor operation will continue even
if the blower is thermostatically stopped.

It is not possible however to operate the
blowers in a different cycle from compressor
operation ; for instance : compressors run­ning in cool cycle and blowers in heat cycle.
In that case compressor operation will have
priority and blower-operation will be stopped
(error code <bA11>).

4. SECONDARY COMMANDS :

The F/Blower key gives immediate access to
commands and displays necessary for day to
day operation. When pushing the F/Blower
key you will see to the left a code which indi­cates the type of display or command and to
the right the present value.

In order of appearance here-after an explana­tion of these commands/displays :

a) Blower speed control : < b A>

(0,1,2,3,4,5)
This command preceeded by the letter b
(blower) allows the following settings :
A = automatic blower speed adjusted to tem-

perature differential.
0 = blower stop
1 to 5 = manual Speed Control
Speed control is in real time mode i.e.
changes are effected immediately without
any validation procedure.

Warning :

All following func-

tions need validation before a new

value is accepted.

Validation is obtained by pushing
the F/Blower key again and by
going to the next function line.

Then final validation will occur
automatically when the display
goes back to room temperature
read-out or final validation can be
forced by pushing the On/Off key
briefly while still in F mode.

Validation is witnessed by the brief

display of the message <memo>.

b) Read out of chilled water temperature :

<H10.2> (10.2 ° C) - for example.

c) Cycle mode choice : <F 3> (1 to 5)
The following cycle modes can be choosen
manually :
1 = cool cycle only
2 = heat cycle only
3 = automatic cycle switching with reversible
compressor
4 = automatic cycle switching without
reversible compressor
5 = heat cycle only without reversible com­pressor

d) AC Voltage read-out : < U232>

(232 Volts)

e) Manual on/off Compressor 1 : <1C01>

<1C01> = Compressor 1 on
<1C00> = Compressor 1 off

f) Manual on/off Compressor 2 : <2C01>

<2C01> = on
<2C00> = off

Idem for compressors 3 and 4 - <3C01> and
<4C01>.

g) Start-up Priority Compressors 1 to 4 :

<P123> = 1,2,3,4 ; <P341>=3,4,1,2

<P A> = automatic priority rotation; when

in this priority mode, the starting
order will be changed at every

restart after a thermostatic cut-out.

h) Time delay between compressor start-up :

<L 9> (9 seconds) - programmable

from 1 and 9 seconds.

i) Individual thermostatic advance compres-

sors 1 to 4. In relation to the general chilled

water temperature set-point, it is possible to

differenciate the cut-out temperature for

each compressor.

Factory default setting : <1L0.0> etc

<2L1.2> means compressor 2 will cut out

1.2° before the general set-point value. So

for a general value of 4°, compressor 2 will

cut out at 4 + 1.2 = 5.2 °.

Same is possible for the other compressors.

j) Automatic dehumidification while absent.

factory default setting : <d 0>
0 = non active
1 = 1 cycle per 24H
2 = 2 cycles per 24H etc

k) Display time of secondary functions (F/

Blower key) by periods of 20 seconds.
<t 1> (factory default setting) = display
time 20 seconds.

4. VISUAL ERROR CODES ­DIGITAL DISPLAY

The following malfunctions will be dis­played directly on the digital display by a
code and will be followed by a system halt
(except for <bA11> - see hereafter).

Whenever any of these codes appear the sys­tem is stopped for approx. 60 seconds and
then a re-start is attempted.

If for more than 30 minutes the same mal­function occurs, the system will be stopped
completely and the error-code will become
steady.

No more re-starts will be attempted and the
user will have to re-set the system by pushing
the On/Off key or by temporarily cutting off
the AC supply to the system.

List of error-codes and nature of malfunc­tion :

Code <AAA> :

Persistent low voltage (voltage below 195V)
for more than 5 seconds - (see also hereafter

- Trouble-Shooting - Page 19).

Code A01 to A08 :

Pressure safety cut-out of compressors 1 to 4.
The HP(High Pressure) and BP(Low
Pressure) safety switches are directly con­trolled by the micro-processor inclusing the
time-delays for re-start, etc.

Error codes displayed and probable nature of
anomaly.

<A01> : BP (low pressure) cut-out - com-

pressor 1 - probable causes :

- interrupted or insufficient water­flow in chiller circuit

- sea-water circulation deficient
when running in heat cycle mode

- insufficient refrigerant charging
level

- abnormal sea-water temperature
conditions in heat cycle (sea-water
temperatures under 6° C. approx.)

- first start-up in heat cycle with
very low chilled water circuit tem-

peratures (below 8° C approx.).

<A02> : HP (high pressure) cut-out - com-

pressor 1 - probable causes :

- insufficient or non-existent sea­water cooling - check sea-water
pump.

- insufficient or interrupted water
flow in chiller circuit when operat­ing in heat cycle.

- too much refrigerant in system ­call a specialist

- abnormal sea water temperature
conditions in heat cycle (sea-water
temperatures above 20° C approx.)

<A03> : BP cut-out - compressor 2 - for

probable causes see <A01>

<A04> : HP cut-out - compressor 2 - for

probable causes see <A02>

<A05> to <A08> - same as above for com­pressors 3 and 4 (if present).

If any of these error codes appear too fre­quently and no appropriate action can be
taken with the available means on board, it is
necessary to call a specialist.

Do not insist with manual re-starts in such
cases as this may cause major damage to the
principal components (compressors, pumps,
etc).

<A09> - absent or defective external air sen-

sor.

<A10> - absent or defective chilled water

sensor.

<bA11> - blower operation from TECC card

impossible because of non-compati­ble water temperature versus pro-

grammed set-point. This is the only
error code which will not result in
a complete system halt.

<CA11> - all compressors are disactivated
by soft - through F/Blower key : <1C00>,
<2C00>, etc.

To reactivate re-program as follows :
<1C01>, <2C01>, etc

Individual cabins controlled by WEBASTO
Digital Cabin Controls are completely inde­pendent from the central condensing unit i.e.
there is no direct electrical or electronic link
between the cabin control unit and the central
TECC controller.

The chilled water temperature sensor allows
the Cabin Control to ascertain which cycle
(heat or cool) is presently valid.

A Cabin Control can be operated entirely
independently from the main condensing unit
i.e. :

- it can be switched off or turned on at any

time by the end-user

- the end-user can set any temperature set-

point as long as it is compatible with

the general operation mode valid (heat or

cool)

- blower operation can be individually con-

trolled and programmed

2) Flashing of Error Code <bA11> :

If the user programs a set-point temperature
incompatible with the general water circuit
temperature as presently available (for exam­ple : set-point requested : 20° C for a room
temperature of 25° C and a water-circuit tem­perature of 35° C) = Cool cycle requested
with the chilled water circuit obviously
working in heat cycle.

Blower operation will be stopped and error
code <bA11> will blink for approx. 10 sec­onds.
After that the error code will still be visible
when accessing blower control by the F key.
The error code will disappear and normal
blower operation will resume as soon as the
water circuit temperature drops below 20° C.

Direct read-out of water-circuit temper-

ature at air-handler entry :

All Cabin Controls allow the user to immedi­ately visualize the water-circuit temperature
at the entry of the cabin’s air-handler. (push
F/Blower key - see also drawing here-above).

This feature allows the user to ascertain that
water-circulation is normal through the air­handler without abnormal differences as
compared with the condensing unit water
exit. (Normally temperature rise between
condensing unit exit and air-handler entry
should not exceed approx. 4° C.) Before get­ting worried however, the first thing to check
is the proper attachment of the cabin control
water temperature sensor to the air-handler
entry and its proper insulation from outside
interference.

5A - DIGTAL CABIN CONTROL ­TYPE CAB - 230V - 2000 SERIES

This is the most common type of digital
cabin control and includes :

- digital display <AIR CONTROL>

- CAB - 230V controller card in plastic box

- 4 ml display cable

- 2.5 ml chilled water temperature cable

- 4 ml air temperature sensor (optional)

The digital display <AIR CONTROL>
includes an air temp. sensor housed behind
the 2 small openings on the front panel. It is
sometimes necessary however to use the
optional external air-sensor if for instance the
digital display is subject to direct heat induc­tion (sun-rays, instruments from behind, etc)

All CAB controls include an outlet for sole­noid water valve control on the entry of the
air-handler.
Solenoid valve control are an optional extra :

Danfoss/Lizhan 3-way solenoid valve sys­tems, where the water-flow is completely
halted when set-point temperature is reached
and the flow returned directly to the return­line through a nozzle.

When using 3-way valves it is possible to
adopt continuous blower operation.

See page 7 - drawing N° 5.1 for full
schematics.

Secondary Commands - <F> key :

The <F> key gives immediate access to com­mands and displays necessary for day to day
operation. When pushing the F key you will
see to the left a code which indicates the type
of display or command and to the right the
present value.

In order of appearance here-after an explana­tion of these commands/displays :

a) Blower speed control : <b A>

(0,1,2,3,4,5)
This function is also accessible directly
through the dedicated Blower key.

This command preceeded by the letter b
(blower) allows the following settings :
A = automatic blower speed adjusted to tem-

perature differential.
0 = blower stop
1 to 5 = Manual Speed Control

Speed control is in real time mode i.e.
changes are effective immediately without
any validation procedure.

b) Read out of chilled water temp. :

<h10.2> (10.2 ° C) - example.

c) Control of external heat-source.

<F 1> = normal auto-reverse cycle
(cool/heat) without external heat source.
<F 2> = autoreverse cycle operation with
external heat assistance. In that case the oulet
connectors <HEAT> on the Cabin controller
card are activated together with the
<VALVE> oultlet when heat cycle is select­ed. This external heat source can be an AC
heating element or any other source such as
ceramic heaters etc
<F 3> = heat operation with external heat
source only. Inthat case the <VALVE> outlet
on the controller card is not activated and
only the <HEAT> connectors are opera­tional.

c) Automatic dehumidification

while
absent.
Factory default setting : <d 0>
0 = non active
1 = 1 cycle per 24H
2 = 2 cycles per 24H etc

d) display time of secondary functions

(F/Blower key) by periods of 20 seconds.
Factory default setting : <t 1> = display
time 20 seconds

Special features - 2000/2004 Series :

See beginning page 4.

Continued features - 2000 Series :

A) Automatic blank/sleep mode - program­mable time delay. Factory default : 15 min-

utes. While in blank/sleep mode the cycle
LED flashes discretely every 20 seconds. To
go back to normal operation push any key.

B) Real time modification of all blower
speed settings.

It is now possible to alter all speed settings (1
to 5) before actually putting the system into
service. To do so entrer programming mode
with set-point at 15° C.; proceed to line<6> =
speed 5 (max).

Alter value and blower speed will immedi­ately change in real time. When satisfied go
to following line <7> = speed 4 and do the
same.

Proceed until lowest speed N° 1 and go back
again to speed N° 5 if not satisfied.

When all speeds are programmed according
to need, validate by pushing on/off key
(<memo> will be displayed briefly).

Attention : Never program speeds so
low that the blower is in danger of
stopping or will not re-start at that
setting. This will inevitably entail
motor-windings burn-out and will
not be covered by WEBASTO war­ranty.

Programming of the CAB - 230V
controller cards :

To access hidden programming functions

raise set-point temperature to 29° or lower to
15° and push On/Off key.
Then push both set-point keys simultaneous­ly for approx. 3 seconds and you will enter
programming mode as explained here-after.

Validation is obtained by pushing the
F/Blower key and by going to the next pro­gramming line.

Programming codes available by raising the
set-point to 29° C :

Code <4> : Calibration of chilled water temp
Code <5> : time delay in minutes before the

display goes into sleep mode.

Code <7> : Calibration of room temperature

read-out.

Code <b> : Program version

Programming codes available when lowering
the set-point to 15° C :
Code <1> - factory setting : 0 - infra-red
remote control :
0 = infra-red remote control disabled
1 = infra-red remote control active
Code <2> : Blower type : Centrifugal or

Cross-Flow. Factory default : 1
0 = centrifugal blowers only
1 = centrifugal + cross-flow

Code <3> : continuous blower operation = 1

thermostatic blower control = 0

Code <4> : integrated air-sensor = 1

external air-sensor = 0

Code <5> : display in Celsius or Fahrenheit

default value = 0
0 = Celsius read-out
1 = Fahrenheit read-out

Code <6> : calibration speed N° 5 (max)

5D - MTH - MECHANICAL THER­MOSTAT

The MTH thermostat has a knob control for
setting the desired set-point temperature and
a selector to switch between summer and
winter operation.
See here-after the electrical schematics of
MTH installation.

5E - MTH2 - MECHANICAL THER­MOSTAT + 3 SPEED CONTROL

The MTH2 mechanical thermostat incorpo­rates a 3 position selector which can be
linked to a simple 3 speed blower control
system.
See here-after (Photo 5.6) for the compo­nents included in this system. The assembly
is delivered with a multi-conductor plug to

avoid cabling errors.
