1. Features
STULZ CompTrol 1002 is a complete control system for A/C-Units. The controller is build
in a compact microprocessor design and is completely digital.The controlling system is
driven by software only.
CompTrol 1002 controls temperature and humidity and supervises the room under free
programmable conditions.
With the CompTrol 1002 single-module CW-units or units with a 2-stage compressor can
be controlled. A 2-unit-sequencing is also included.
Functions such as cooling, reheat, humidification and dehumidification are continuously
controlled and supervised. In case of any deviation from setpoints, the CompTrol 1002, will
initiate necessary measures immediately. Parameters for the control system and the
functions that have to be controlled can be directly programmed by three keys on the
CompTrol 1002.
CompTrol 1002 can be connected to the STULZ Monitoring Systems InCompTrol and
TeleCompTrol.

4-Digit LED-Display
In this LED-display all controlling parameters such as setpoints, actual values and limiting
values, are shown.
Status LED
Status LED show actual operation mode of controller. As a function switches on, the
corresponding Status LED is indicated. On a CW-Unit, Status LED "cooling" indicates when
CW-valve has an operation level greater than 0%.
Status LED "alarm" indicates when an alarm occurs.
DIP-Switch 1-4
Adjustments that need not to be changed after initial installation, are made by these DIPswitches. DIP- Switches 1-4 have the following functions:
DIP-Switch 1
DIP-Switch 2
No function
Modification from Version 2.1: When the sequencing is
active (i.e. menue point 24 > 0), the start of the stand-by unit can
be chosen by this switch.
ON:
no start by passing over a limit value
OFF:
Start of stand-by unit in addition, 3K before the limit
value "Temp. too high" is reached.
The control of the compressor version or the CW version can be
chosen by this DIP-switch.
OFF:
Control of compressor version is chosen.
ON:
Control of CW version is chosen.
Some menue points, alarm inputs and outputs will receive another meaning.
DIP Switch 2 must only be switched when dead.
DIP-Switch 3
Two alarm inputs can be chosen by this DIP- switch.
ON:
The inputs "auxiliary alarm 1" and "auxiliary alarm 2"
have the function of external alarms.
OFF:
The input alarm 2 has the function of firestat- and
smoke detector.
The input alarm 1 has the function of water sensor.
E / 0 5 9 7 /50/ 5
Consequences of alarm inputs "auxiliary alarm 1" and "auxiliary alarm 2"
depends on position of DIP- switch 3. DIP- switch 3 can be switched at any
time, even during controller operation. The function of this switch is
immediately valid without further measures.
DIP-Switch 4
Temperatures in °C or °F can be chosen by this DIP - switch.
OFF:
All absolute temperatures are shown in °C.
Temperature differences are shown in K. Actual
value is marked with a C.
ON:
All absolute temperatures are shown in °F.
Temperature differences are converted to degree
Rankin and indicated. Actual value is marked with an
R.
DIP - switch 4 can be switched over any time, even during controller
operation. Function of switch is valid without further measures.
Membrane Keys
Key
Operation mode "start" and "stop" are the only functions of this key! If the controller is in enter
mode, the key is ineffective.
Operation Mode "Stop"
Control system and unit are not in operation. CW-valve closes. Limiting values are
supervised. Independent failures (like sensor break-down, water sensor alarm, firestat
alarm, smoke detector and other external alarms) are supervised. Display indicates
.
The horizontal bar in display means that controller has been locally turned off by the
key.
Occuring alarms and failures can be reset in menue point 1. Inputs and modifications in
all menue points can be made.
E / 0 5 9 7 /50 / 6
Operation Mode "Start"
Control system and unit are in operation. Unit functions are turned on when start values
match setpoints of corresponding functions. Limiting values are supervised. Menue point
1 is shown. Display is alternating between actual value "temperature" and actual value
"humidity" in 2- second- intervals.
Occuring alarms and failures can be reset in menue point 1. Inputs and modifications in
all menue points can be made.
Right Arrow
Key
This key has several functions.
Menue Point 1 And Operation Mode "Stop"
Alarm reset is activated by pressing the key.
Menue Points 2 to 24
The setmode for these menue points is activated by pressing the key. After pressing this
key there is a request for entering in the password.
Enter Mode
This mode can be initiated by pressing the key and the enter mode is left. The value
shown last is taken into the continuous memory and is used for controlling.
Up Arrow
Key
Next menue point can be entered by this key. The shown value is increased in enter mode.
Down Arrow
Key
Last point of menue can be reached by pressing this key. The shown value is diminished
in enter mode.
Pressing one of these two keys longer than one second in enter mode means
pressing this key 12 times.
If none of the keys is used within five minutes, there will be an automatic return to menue
point 1.
E / 0 5 9 7 /50/ 7
3. Start-up
Prior to initialization, the software version number is displayed for about 1 s.
Example:
Software version 2.1
When the C1002 is started (operation voltage is supplied) the following symbol appears in
the display for one second during initial phase:
In this initial phase all values of the continuous memory EEPROM are loaded into working
memory.
Independent of the requirements for a certain function the CW- valve is closed for the time
entered in menue point 8. This procedure is designed to synchronise the control system with
the modulating valve.
Start- up in Operation Mode "Stop"
If the CompTrol 1002 was in operation mode "stop" before cutting off the power supply, the
controller will be in this operation mode again after restarting. If this happened there are
three different procedures to follow:
Display
1. I/O-Key: local mode
2. Remote On/Off: remote mode
3. Software On/Off: Monitoring system
If controller is stopped from different locations, this identifies by the location of the bar in the
fourth character position on the display. Restarting is only possible if local start mode (I/OKey) exists. The I/O-Key has the highest priority.
Start-up in Operation Mode "Start" (Autostart)
The CompTrol 1002 is equipped with an "autostart"- function. This means that the unit starts
automatically when it was in operation mode "start" before. A restart of several units with
the C1002 at the same time can be avoided by entering a time delay in point of menue 22.
E / 0 5 9 7 /50 / 8
Start-up with Standard- Program
If the two keys which represent the password are pressed at the same time as power is
turned on, the following reading appears on the display:
At this time the standard program is loaded from program memory EPROM to continuous
memory EEPROM and working memory. During this procedure the control system is not
working. By loading the standard program the controller is switched off locally and has to
be set in operation mode "start" by pressing the
key.
Start- up with new Continuous Memory
If the CompTrol 1002 is started with a new continuous memory, the following symbol
appears in the display during the initial phase (about 1 second):
At this moment, the standard values of the program memory are loaded to steady memory
and to working memory. During this procedure the control system is not working. By loading
the standard program the controller is not working. By loading the standard program the
controller is switched off locally and has to be set into operation mode "start" by pressing
the
key.
Warm start
The Controller CompTrol 1002 is equipped with a "watchdog-timer". This "watchdog-timer"
increases the safety of the controller and restarts the program if a runtime error occurs. If
a warm start occurs the following reading appears in display:
If the C1002 was in operation mode "start" before a warm start occurs the autostart function
is activated.

The parameters of the compressors' start
and hysteresis can be entered in these
menue points (9b-11b).
Maximum operation level "dehumidification" can be passed over when the
CW-valve´s operation level for cooling is
increased.
Menuepoint 11b is only relevant, if a
second compressor exists.
If the proportional range or hysteresis is set to actual value "0" the corresponding function
is not required, the status- LED is not activated and the corresponding failures are not
evaluated.

Start Value Dehumidification
CW-units:
For dehumidification CW-valve opens to the indicated operation level entered in
point 11a of menue.
Units with compressor:
The dehumidification saver circuit and the compressor will be started.
The "dehumidification" function is stopped when temperature is less than 0.5 K (0.9R) over
limiting point low temperature (room). It is set free again by a hysteresis of 0.5 K (0.9R).
Modification from version 2.1:
3K (5R) underneath the temperature setpoint the dehumidification is stopped.
This way a fall of the room temperature by holding the humidity setpoint is
avoided.
18
Hysteresis Dehumidification
Parameters for dehumidification are entered in this point of menue.
Basically a function is set passive, if the corresponding hysteresis is
set to zero.
If hysteresis of humidification and dehumidification is set to zero, the
limiting point "humidity" is not supervised.

Temperature Sensor Adjustment
Temperature sensor adjustment can be done in this point of the menue. Actual
value is indicated and can be adjusted to another value, that is measured by use
of an independent temperature meter.
Display is in reference to position of DIP- switch 4 degrees Celsius or
Fahrenheit.
By loading the basic program of the controller, sensor adjustment is
restored.
21
Humidity Sensor Adjustment
Humidity sensor adjustment can be done in this point of the menue. The actual
value taken from a reference measurement has to be entered.
By loading the basic program of the controller, sensor adjustment is

Integral Factor
for Setpoint “Temperature”
In this point of the menue, the I-proportion of the PI controller can be preset. If
a non-zero value is entered, the “offset behaviour” of a mere P controller is
inapplicable. The setpoint SP1 entered becomes “control setpoint”. Now, it is no
more a constant value but is changed in integral intervals of 5 minutes and
indicated in the menue point 2 “temperature setpoint”. Alteration of the setpoint
is made using the following formula:
∆ SP = (Setpoint - Actual Value) x Integral Factor %
which results in
Control Setpoint SP2 = SP1 + ∆ SP
Actual value
a) modification of setpoint
in enter mode

control setpoint
The originally entered setpoint SP1 appears in the enter mode, which can be
changed in this point of menue and which is immediately rendered valid after the
alteration has been made (refer to illustration: a) ).
The values of the integral factor may be between 0 and 80%. As a rule, a low value
should be used to start with, as with a too high value, the system will start
vibrating. 10% are proposed, which shall be slowly increased, until the system
has been adjusted.
E/0597/50/18
Menuepoint
For test purposes or in case the I-proportion should be undesirable, the integral
factor is set to zero. A P controller exists and the control setpoint is equal with the
setpoint.
Under the following circumstances, the setpoint is immediately taken
over into the control setpoint:
- during initialization phase (make alive)
- turning on (start mode)
- failure “sensor break-down” active
- limiting alarms “temperature” active
- modification of setpoint
The range of the control setpoint is limited to setpoint ± 3 K (± 5.4 R).

If "255" is set in the input mode, the unit is marked
as the "2nd" unit. No adjustments are carried out
on this unit. The sequencing time is only set and
displayed on the „1st“ unit.
In case of failure (unit 1 or unit 2) the sequencing time is frozen. This state is
maintained until a failure reset is carried out. After that sequencing continues as
normal.
E/0597/ 50/19
Menuepoint
If unit 1 is the StBy-unit (i.e. the unit, which is not in operation at the moment, due
to the sequencing), a colon („:“) is displayed under menu point „U“. If unit 2 is the
StBy-unit the colon disappears.
3K before the alarm „temperature too high“ the StBy-unit starts in addition. The
sequencing time will not be interrupted. At a hysteresis of 3K the unit stops again.
The sequencing uses the standard inputs for remote on/off and water detector/
Aux1 and the standard outputs for common alarm and heating 2.
If the input Aux1/water detector and/or the output heating 2 is needed, an extension
board is installed, where one input and output are available for the sequencing.
That way the 2nd heating stage and the water detector input are available again
on the processor board.
As the sequencing is carried out by using the input for remote on/off, the display of
the StBy-unit shows:
A connection scheme for both units is shown on the pages 29 and 33.

Actual Operation Level CW Valve
In this menue point, the actual operation level of the CW valve is displayed.
This menue point exists only at CW-units.
E/0597/50/20
5. Alarms and Failures
General
An alarm or failure is indicated via a short text in the display and status-LED´s.
Conditions that activate the alarm-relay are shown in the following table. Each alarm or
failure causes a certain delay, which also can be taken out from the table.
Texts for alarms and failures are only shown in operation mode "start", in point of menue
1 , and in operation mode "stop". All alarms and failures that have occured up to this time
and corresponding operation- modes are indicated by showing up every four seconds.
Warnings
Warnings have no direct influence on the function of the unit, i.e. after a warning has
occured, the unit can be continued in operation for a while. The alarm relay is not activated.
These functions are only supervised in start mode:
- Ultrasonic humidifier (5µS/cm)
- filter
Alarms
Actual values are supervised not to reach limiting points. After a delay of about 30 seconds
the limiting alarm is activated. Limiting points are supervised even in operation mode "stop".
Alarm "humidity" is only evaluated if dehumidification and humidification hysteresis
is not set at "0".
Failures
Failures on the following functions are only supervised in the operation mode "start":
- reheat
compressor 1 low pressure
- humidification (20µS/cm)
compressor 1 low failure
- airflow
compressor 2 low pressure
compressor 2 low failure
Failures on the following functions are also supervised in the operation mode "stop".
- Aux 1 / water sensor
- Aux 2 / firestat and smoke detector
- sensor break-down
E/0597/ 50/21
If the alarm input is supplied with 24V, there is no failure/alarm. If the alarm inputs are not
used they have to be supplied with 24V or, if possible, the hysteresis of the function has to
be set to „0“. The inputs concerned are:
Heating 1 and 2
Air volume 1 and 2
Water sensor/Aux 1 Alarm
Fire/Aux 2 Alarm
High pressure, low pressure failure compressor
Humidifier alarm / 20 µS/cm
Alarm 5 µS/cm
Filter alarm

In a CW application, the CompTrol 1002 is usually used for a proportional valve with motor
drive. The operation of the control is explained in the following drawing (example for a 150seconds-runtime).
Operation
level / %
When connection V+ is supplied with power, the valve is completely opened within 150
seconds (operation level 0% to operation level 100%). Shorter times mean steeper
operation level. When connection V- is supplied by power the valve is closing. If there is a
power interruption to the valve, the last operation level is fixed.
The consumer is connected to 24V.
Examples:
Valve
Contactor
The function of a triac cannot be checked by means of an electronic continuity tester or
an ohmmeter. Measurements provided by these instruments would deliver wrong readings
because a triac needs a load for a correct function. For an operational test, a continuity tester
with filament lamp (about 2 W) should be used.
Inputs are designed for 24 V AC, but also a voltage 24V DC can be used.

Specifications of the Extension Card 1b
Characteristics
With the extension card 1b, additional inputs and outputs are provided to the CompTrol
1002. The extension card 1b is fastened to the CompTrol 1002 by means of the two distance
pieces enclosed. Electric connection to the basic board is made with a 20-channel plug
connector. As soon as the extension card has been connected, alarms aux 2 / firestat and
smoke detector and Ultrasonic humidifier 5µS/cm are only valid on the extension board.

Configuration of a second compressor.
ON:
A second compressor is available. The DIP switch
on the rear side of the CompTrol 1002 must be set to
OFF (Compressor version).
OFF:
A second compressor does not exist.

Function of Extension Card 1b
Compressor Sequencing
If two compressors are configured, these are subject to compressor sequencing, in
accordance with the “first in - first out” principle, i.e. should both compressors be turned on,
the compressor that had been turned on first will be turned off first. Start value parameters
(menue points 9 and 11) will be changed internally, not visibly, upon each compressor start.
Temperature Limit
The input "Temperature Limit" exists. As soon as a voltage of 24 V is applied to this input,
cooling is interrupted.
That means for
- CW version: The CW valve closes
- Compressor version: The compressors are switched off.
