OPERATING MANUAL G-403-P04 PAGE 4
PPUH „GECO” Sp. z o.o. 2ND EDITION from 2004-09-20
1. GENERAL CHARACTERISTICS.
An autonomous control unit G-403-P04 is used to control pump operation and to stabilise
temperature in systems with solar collectors.
The G-403-P04 controller is a convenient, modern and easy to operate unit. It was made using a
microprocessor technology with automatic surface installation.
Depending on the method of installation the two-part casing allows to install the control panel
operated at safe voltage practically at any place without the necessity to mount feeding cables far
away from the controlled units.
The G-403-P04 controller is provided with:
• Three temperature sensors:
1. to measure the temperature of the solar collector,
2. to measure the temperature of the isothermal tank,
3. to measure additional temperature depending on the configuration.
It has also outlets which allow to connect units which are operated at voltage 230 V directly,
including: the PK main collector pump, an additional pump (PKT,PC,PK2) or a three-way valve
(ZT,ZP)
Adjustable parameters can be set in current operation conditions and in accordance with the
type of installation. The controller is provided with a system which protects it against the effects of
blackouts and various types of disturbances.
The controller does not require any special maintenance, the keyboard is made from special
foil which is resistant to high temperature and most chemicals. Cleaning of the keyboard with sharp
objects is not allowed; cleaning of the face of the keyboard with a wet cloth from time to time will be
sufficient.
In summer the controller should remain connected to mains, nevertheless, it should be
disconnected from mains during storms.

3. ELECTRIC INSTALLATION AND THE RULES OF
CONNECTION
1. The room in which the controller is connected should be provided with electric circuit
230V/50Hz in accordance with effective regulations.
2. The electric circuit (regardless of its type) should be ended with a plug-in socket provided
with a protective contact. Use of a socket without a protective clamp may cause an electric
shock!!!
3. The controller should be connected to a separate electric line protected with a 2-4A quick-
break fuse and an anitishock circuit-breaker with maximal activating current 30 mA.
Do not connect any other equipment to this circuit!!!
4. The clamping couplings have a permanent 16 A load certificate!!! They have a fine thread
and special plates which prevent wire cutting, therefore, light tightening of a wire results a in
a maximally good contact and use a bigger force may cause a damage of the thread.
5. Electric cables have to be well-fastened along their whole length and can not touch pipes with
glycol, the tank or pumps.
6. When the unit is connected to mains, live current can be in cables regardless whether the
button is on or off, therefore ALL REPAIRS must be done when power is
disconnected on the fuse!!!
Caution!!!
Additional equipment may be connected to the G-403-P04 controller only
by a person authorised to do electric installation works.
4. OPERATION AND THE METHOD OF CONTROL OF SBR
G-403-P04
4.1. Measurement of temperature
The controller measures temperature within the range from 0oC to 100oC. It is displayed with
a delay of 1 second. If there is a breakdown of temperature sensor or the measured temperature is out
of the range defined above (unless the unit is waiting for 60 s for stabilisation of voltage after its
disconnection) the controller informs of a breakdown of the sensor which causes that all connected
units are switched off (i.e.. the ventilator, the feeder and the pump), the unit is switched into manual
operation mode and the sign AL1 is displayed on the display if there is a breakdown of the T1
temperature sensor, AL2 is displayed on the display if there is a breakdown of the T1 temperature
sensor and AL3 is displayed on the display if there is a breakdown of the T3 temperature sensor.
Temperature of exactly 100o C will cause a display of the sign 00o.
4.2. Disconnection of the feeding voltage
After disconnection of the feeding voltage the controller begins its operation depending on
the mode in which it was set before the disconnection. The controller waits for 1 minute for
stabilisation of the electric current and returns to operation with parameter values which were
programmed before.

5. OPERATION OF G-403-P04
5.1. Activation of the unit
1. Connect the unit to mains (put the plug in a socket).
First, four dots will appear on the display; then a factory program version will be seen, four
dots followed by four horizontal dashes (----) which signal that the unit is in a stand-by
position. All functions, in particular all control units connected to the controller which control
operation of the controller system, are switched off. In this position the unit does not react to
pressing of any buttons except from the button .
2. Switch on the controller using the button .
3. When the button has been pressed, the controller begins to control pump operation
automatically and reads the latest parameters programmed by the user (see item 6).
The display shows water temperature measured by the T2 sensor in the isothermal tank.
5.2. Manual (master) operation
In the automatic operation mode the user may connect the pump engine manually regardless
of the current temperature and set parameters:
1. PK collector pump:
When the button is pressed, the collector pump connected to the controller is switched
on and the upper indicator on the button is switched on permanently. When the button is
pressed again, forced operation of the pump ends and the controller controls it depending on
whether temperature conditions of its operation are met or not. If the pump is switched on
automatically, the indicator on the button flashes.
2. An additional pump (PKT,PC,PK2) or a three-way valve (ZT,ZP):
When the button is pressed, the collector pump connected to the controller is switched
on and the upper indicator on the button is switched on permanently. When the button is
pressed again, forced operation of the pump ends and the controller controls it depending on
whether temperature conditions of its operation are met or not. If the pump is switched on
automatically, the indicator on the button flashes.
The collector and the additional pump may be switched on and off independently of one another.

5.3. Automatic operation
1. PK collector pump operation
A decision on switching on of the PK pump engine is made by the control on the basis of
information received from temperature sensors placed in the solar collector (T1)
and the isothermal tank (T2). If the difference of temperature of the solar collector and the
isothermal tank is a positive figure and bigger than the value set by the user in the ‘u0’
parameter (⇒ see: ‘Types of controller operation’) and the maximal temperature of the tank
‘u1’ has not been exceeded, the PK main collector pump is switched on and the solar
collector is the source of energy which is used to heat water in the tank.
2. Additional pump or a three-way valve operation
An additional pump or a valve are controlled depending on the chosen type of controller and
were described in item 8 (Types of controller operation).
When the button is pressed, the programming mode which does not influence automatic unit
operation is chosen.
During a normal (automatic) operation of the engine of a given pump, the diode on the
corresponding pump button is flashing and during its forced manual operation it is lit permanently.
5.4. Temperature view
The controller offers to the user a possibility to view the temperature in the solar collector. The
button should be pressed to do so. The button is used to check temperature which is
measured by an additional sensor (whose position depends on the programme of the controller).
5.5. Alarms
The controller differentiates three types of alarm. In every type of alarm the number of alarm is
displayed and an acoustic alarm outlet in the control panel is switched on. Only after pressing of the
button, alarm will end. Automatic operation of the unit can be restarted only after a removal
of the defect.
Types of alarms:
• AL1 → Damaged temperature sensor of the solar collector (T1)
• AL2 → Damaged temperature sensor of the isothermal tank (T2)
• AL3 → Damaged additional temperature sensor (T3): location depends on the programme
version and the type of installation
When temperature in the isothermal tank defined in the ‘u1’ parameter is exceeded (a standard
temperature is 90 0C) the engine of the PK collector pump is switched off unconditionally.

6. COFIGURATION OF USER PARAMETERS
When the button is pressed, the controller is set in the programming mode which is signalled by
switching on of the indicator on the button . Programming does not influence current operation
of the controller.
Programming should be done carefully. It is advisable to put down the values of particular
parameters on a sheet of paper before the beginning of programming. Please, remember that a
mistake in programming may cause a defective operation or make correct operation of the system
impossible.
Caution!!
The meaning of parameters depends on the type of controller chosen by the installer!!! See:
‘Configuration of the type of controller’
1. Set the required value of parameters using the buttons , .
The permissible range of changes if a given parameter depends on the type of the controller
(type of installation).
2. Press the button again and the new value of a given parameter will be memorised.
The controller automatically moves to programming of the following parameter.
Notes:
• If the button is not pressed again, the changes will not be recorded.
• If during setting of the new temperature none of the buttons , , , is pressed
within 20 seconds, the new value will not be recorded and the controller will end the
programming mode.
This parameter is modified in an analogous way to the one defined in items 6.1 and 6.2.
When the button is pressed again, the unit will return to the situation before the beginning of
programming and the programming indicator will appear.
7. CONFIGURATION OF THE TYPE OF CONTROLLER
The type of the controller depends on the needs of installation in which it is to operate.
To change the configuration of the type of the controller, do as follows:
1. Switch off the controller with the button .
Four horizontal dashes will appear on the display.
ª

PPUH „GECO” Sp. z o.o. 2ND EDITION from 2004-09-20
2. Press the three buttons: ,
PUMP
, at the same time for about 3 seconds. The controller
moves to the programming mode which is signalled by switching on of an indicator on the
button and appearance of the ‘c0’ symbol followed by the value of that service
parameter.
3. The‘c0’ parameter means the choice of the type of controller (range: 1 – 6):
-‘1’: basic version with one collector (fig.1),
-‘2’: a version with one collector and operation of a pump for the central heating boiler. (fig.2),
-‘3’: a version with one collector and operation of a pump for the CWU tank (fig.3),
-‘4’: a version with one collector and the function of swimming pool heating through the ZT valve
(rys.4),
-‘5’: a version with two collectors (fig.5),
-‘6’- : a version with one collector and operation of floor heating through the ZP valve (rys.6),
4. Set the required value of the parameter using buttons .
When an arrow is being pressed for a longer time the value is automatically increased or
decreased depending on the chosen direction of changes. Values are interconnected so when
you reach the extreme value at one end it goes to the extreme value on the other end.
5. Press again and the new value of the parameter will be recorded.
At the same time the controller turns to reset and then to the stand-by function and the
programming indicator on the button is switched off.
6. Switch the controller on with the button .
The controller will restart its operation according to the newly recorded programme.
When the button is pressed at any moment, the controller will be switched off without
recording the modified parameter in its memory and the control indicator will be switched off.
Notes on programming of SBR:
1. THE PRODUCER IS OBLIGED TO INTRODUCE NEW PARAMETERS WHICH
ARE NECESSARY FOR NORMAL OPERATION OF THE UNIT!
2. When the unit is programmed and started up its operation and correctness of the setting of
user parameters should be checked.

8. THE CONTROLLER SYSTEM
8.1. A basic system with one controller
Fig.1
Parameters available to the user
‘u0’ – (range 2-30 oC) : temperature difference which controls work of the main collector pump
‘u1’ – (range 10-90 oC): maximal temperature of the isothermal tank above which the collector pump
will be switched off
In this system the collector pump is operated in accordance with the description in item 5.3 and the
additional pump is not used. If the T3 sensor is not installed, the view of its temperature is blocked
and the AL3 alarm from that sensor is not signalled.
8.2. A system with one collector and operation of the pump for the central heating boiler.
Fig.2
Parameters available to the user
‘u0’ – (range 2-30 oC): temperature difference which controls work of the main collector pump
‘u1’ – (range 10-90 oC): maximal temperature of the isothermal tank above which the collector pump
will be switched off
‘u2’ - (range 10-90 oC): the temperature below which the PKT boiler pump will be switched on
In this system the collector pump functions in accordance with the description in item 5.3 and the
PKT boiler pump is an additional pump. It will be connected if the sensor temperature T3 is lower
than the temperature set by the user in the parameter ‘u2’.
