1.1 Purpose of the document

This workshop manual is used to support instructed personnel
when adjusting the parameters of the control element for trans­port refrigeration.

1.2 Using this document

X Read this document before changing parameters.

X Read the operating instructions.

1.3 Use of symbols and highlighting

Explanation

Requirements for the following necessary action.

Note on a special technical feature.

Separate information is available.

ATTENTION: Possibility on property damage.

WARNING: Possibility on minor or moderate injury.

DANGER: Possibility on a severe or mortal injury.

2.1 General safety

The repair and commissioning personnel must have the following
qualifications:

■

Successful completion of Webasto training.

■

Corresponding qualification for working on technical systems.

■

Certified to work on air conditioning systems.

The repair and installation of the unit may only be carried out in
accordance with the workshop manual and the installation in­structions.

2.2 Intended use

The system is designed for cooling the load compartment of com­mercial vehicles while driving.

The performance values of your application are
closely related to ambient conditions, vehicle insula­tion, etc. The actual temperature may therefore de­viate from the set value.

In the case of vehicles fitted with automatic start­stop control, the function must be switched off
while operating the refrigeration system. For infor­mation on the control and function of the automat­ic start-stop control, please read the operating in­structions for your vehicle.

1.4 Warranty and liability

Webasto shall not assume liability for defects or damage that are
the result that the installation, operating instructions and as well

■

Improper use

■

Repairs not carried out by a Webasto service workshop

■

Use of non-genuine parts

■

Conversion of the unit without permission from Webasto

■

Mechanical damage to the equipment

■

Failure to comply with inspection and maintenance instructions

ATTENTION
Misuse as a result of failure to comply with the
workshop manual

Result: damage to the refrigeration system

X Follow the operating instructions and instructions

described in this document.

more information.

3.5 The programming tool or “hot key”

You can program the control element quickly or restore parameter
settings with help of a programming tool, called the “hot key. See

3.6 Hours of compressor operation

There is a counter (in hours) that saves the compressor operation
hour count. The resolution is 1 hour and the range goes from 0 to

50.000 hours. Saving interval: 5min.

Example:

If the saved value is 1511 hours of operation, the first time the
button is pressed “001” (thousands) is displayed. The second time
the “Clock” button is pressed “-511” (units) is displayed.

X Press the “Clock” button:

–

The compressor operation count, in hours,
appears on the display. The first value displayed
indicates the thousands.

X Press the “CLOCK” button again:

–

The units of the compressor operation count
appears on the display; preceded by a minus
sign.

Fig. 02: ”Thousands” indication

Fig. 03: ”Units” indication

Repeatedly pressing the “Clock” button toggles between the two
values.

During display of the compressor operating hours only the “Clock”
LED remains on.

When no key is pressed for 3s, the instrument goes back to nor­mal display.

The user cannot reset the saved value. Only Dixell
can reset it, using a special reset procedure.

has 2 functions:

■

Download parameters from the hot key into the control element.

■

Upload parameters from the control element into the hot key.

Uploading parameters from the control element into the hot key provides a back up for eventual restoring parameter settings or to pro­gram other control elements with the same set of parameters quickly.

Compressor Cut OUT is when the temperature reaches the set point.

LS Minimum set point:

Sets the minimum acceptable value for the set point.

US Maximum set point:

Sets the maximum acceptable value for set point.

ot Thermostat probe calibration: allows to adjust the possible offset of the

thermostat probe.

P2P Evaporator probe presence:

n = not present: time stops the defrost cycle;
y = present: temperature stops the defrost cycle.

oE Evaporator probe calibration:

Allows to adjust possible offset of the evaporator probe.

odS Outputs activation delay at start up:

This function is enabled at the initial start up of the instrument and inhibits
any output activation for the period of time set in the parameter.

db Dead band (= neutral zone); allows the system to control the cell tempera-

ture to higher or lower temeratures compared to the set temperature. To
be used in case of heating kit.

n = neutral zone disabled; cooling only
y = neutral zone enabled; heating kit installed

AC Anti-short cycle delay: minimum interval between the compressor stop and

the following restart.

CCt Compressor ON time during continuous cycle:

Allows to set the length of the continuous cycle: compressor stays on with­out interruption for the CCt time. Can be used, for instance, when the room
is filled with new products.

CCS Set point for continuous cycle: it sets the set point used during the continu-

ous cycle.

Con Compressor ON time with faulty probe: time during which the compressor

is active in case of faulty thermostat probe.
With Con = 0 the compressor is always OFF.

CoF Compressor OFF time with faulty probe: time during which the compressor

is OFF in case of faulty thermostat probe.
