collectors. The product was base on a reliable state-of-the-art microprocessor technology. The
Controller is modern in its design and very easy to use as it is equipped with a user panel with a
transparent keyboard and an LCD graphic display.
Its advantage is an extensive package of basic options greatly enhancing its functionality. These are:
A selection of 17 various system configurations,
System scheme display,
Device operation animation in the system scheme,
Collector pump rotation speed adjustment,
External device manual control option,
Calculation of collector instantaneous power,
Inbuilt real-time clock,
Controller status memory after disconnecting power supply,
Extensive average collector power statistics menu,
Extensive energy counters menu,
Holiday function,
Anti-legionella function,
Collector overheating prevention function,
Anti-freeze function,
Collector type selection function (flat plate / tube).
Additionally the Controller has been equipped with a number of features facilitating its use:
Transparent menu,
Graphic presentation of time intervals,
Selection of many language versions,
Easy and quick control settings configuration.

GH20SB – User Manual PAGE 5
PPUH “GECO” Sp. z o.o. FROM 05/01/2015
2. Connecting External Devices
The GH20SB Controller is equipped with 4 inputs enabling connection of NTC10K
temperature sensors and three outputs enabling connection of external devices, pumps or three-way
valves, depending on the system scheme chosen. A drawing contains a graphic presentation of the
input and output marking. The description of the Controller inputs and outputs is provided in the
table.
Marking of Controller inputs and outputs
Input/Output Description
Un Mains connection (230VAC~/ 50Hz)
O1 Main pump output
Maximum current rating: 3.15A
O2 Relay output – dry, switch relay
Maximum current rating: 8A
- S1-S2 – NC (normally closed),
- S2-S3 – NO (normally open).
O3 Relay output – live, 230VAC~
Maximum current rating: 8A
O4 Mains power outlet 230VAC~ bridged within the Controller. This output
may be bridged outside with the switch relay output, thus providing
switching power supply for controlling e.g. a three-way valve.
T1,T2,T3,T4 Temperature sensor inputs – NTC10k
Description of Controller inputs and outputs
When connecting devices to the Controller outputs it must be remembered that outputs
marked as O1 and O3 are live outputs to which an external device may be connected directly. The
O2 output is dry and to be placed in series between the power source and the external device.

PPUH “GECO” Sp. z o.o. FROM 05/01/2015
3. Controller Usage
The GH20SB controller can’t be connection with electronic flow meter. Before
you start using controller make sure that “Measurmem” parameter is adjust to
“Rotameter”. (pkt. 3.3.4.5.)
3.1. Enabling the Controller
After connecting the Controller to the power supply, controller for about 5 second make
touch-pad keyboard calibration, and inform user about this fact by inscription on the display:
“Keyboard calibration, Do not touch sensors”
After connecting the Controller to power supply the Collector will be activated in the
standby mode (if before deactivation it was in the standby mode) or in the operation mode (if before
deactivation it was in the operation mode).
If touch sensors display doesn’t work correct please make calibration process again.
Before you start next calibration Please turn of the controller from the power supply for a moment.
3.2. Standby Mode.
In this mode the LCD display is slightly backlit and the Controller name and the current
software release are shown on the screen.
In the standby mode all outputs remain disabled and the alarm sounds are inactive.
Press to cause the Controller to exit the standby mode and switch to the operation mode.
3.3. Operation.
3.3.1. Main Screen.
In the upper line of the LCD display, on the left, the number of the currently supported
system scheme is shown. In the middle and on the right the time and date are shown. Below the
time and date line, on the left, the system scheme and the collector pump control level are
displayed. The digits in the scheme represent the numbering of the temperature sensors. You need
to ensure that the sensors are properly installed, as described in the scheme. Sensor substitution may
result in control system malfunction.
On the right of the system scheme the temperatures measured by sensors are shown. T1
corresponds to the temperature measured by sensor 1, T2 corresponds to the temperature measured

GH20SB – User Manual PAGE 7
PPUH “GECO” Sp. z o.o. FROM 05/01/2015
by sensor 2 etc. The Controller is designed to ensure that it is not necessary to install all four
temperature sensors. You need to install only those sensors which are necessary for control. If a
sensor necessary for control is not installed or damaged, next to the sensor symbol on the screen the
word ”Err” will appear, indicating that there is no sensor or it is damaged. In this case all external
devices will be deactivated and the Controller will raise alarm indicated by an intermittent audio
signal. If a sensor not required for control is not connected to the controller or is damaged, the
Controller will not raise alarm, and on the screen the temperature will be replaced with the symbol
“-----”.
Below the displayed temperatures, in the lower right-hand corner of the screen, the
collectors’ instantaneous power is displayed as calculated by the Controller. When the collector
pump is deactivated or the sensor on the collector return (as a rule it is sensor T3) is disconnected,
the power indication is replaced with the symbol “-----”. For systems numbered 6, 10, 12, 14, 15
and 16 the power calculation option is not available.
Depending on the control status, additional symbols may appear on the screen, such as:
“L” – active anti-legionella function.
Holiday symbol – active holiday function.
Cooling symbol – active cooling function.

The Controller has an inbuilt module for recording average collector power and the energy
generated by the collectors. The Controller enables recording and readout of power and energy
statistics for the following time intervals:

Last 60 recorded days,
Last 20 recorded weeks,
Last 12 recorded months,
Last 10 recorded years,
Additionally, for days, weeks, months and years statistics there is possibility to present the time
intervals graphically, by means of bar charts:
For daily statistics it is possible to graphically present the hourly distribution of the average
collector power and energy,
For weekly statistics it is possible to graphically present the distribution of average power
and energy for individual days in the interval from Monday to Sunday,
For monthly statistics it is possible to graphically present the distribution of the average
power and energy for individual days, The interval depends on the number of days in the
month viewed,
For annual statistics it is possible to graphically present the distribution of average power
and energy for individual months in the year in intervals from January to December.
When the graphical presentation in the form of bar charts is displayed, in the left upper-corner of
the screen the highest value in the given interval appears, to which the height of each bar is scaled.
Additionally, in the right-hand upper corner the series recording date appears.
The energy counters menu includes also the total energy counter. This counter counts, on a
continuous basis, the energy generated since the Controller activation.
The statistics and the total counter may be reset anytime. The reset options are to be found in
the energy counters menu and available separately for the total counter and for the statistics.
A change of date may disturb the sequence of the recorder data.
To view the energy counters or reset the counters, choose “Energy statistics” on the main menu
screen.
