1. Description of the controller
G422-P01 Controller is a device designed and produced to be used with solar collector installations. This product has been created on the basis of a
faultless modern microchip technology. The controller has a modern look and is very easy to use, thanks to its user panel which features a simple keyboard
and an LCD screen.
A powerful feature of the controller is its extended packet of basic options, which significantly increases its functionality. These include:
 A selection of 9 different installation configurations,
 Installation diagrams displayed on the screen,
 Animation of operating devices in the installation diagram,
 Regulation of the collector pump speed,
 Possibility of manual control of external devices,
 Calculating momentary collector power,
 Built-in real-time clock.
 Storage of controller settings while disconnected from power
Additionally, a number of functions improving the use of the controller have been introduced:
 Simple menu
 Graphic representation of time periods
 Multiple language versions
 Easy and fast configuration of control parameters
2. Connecting external devices
G44-P01 controller features four inputs allowing for the connection of NTC10k type temperature sensors, and three outputs allowing for the connection of
external devices, pumps or three way valves, depending on the selected installation type. Graphic representation of input and output labelling is shown in
picture 1. The description of the controller's inputs and outputs is presented in chart 1.

Input/Output Description
220V~ Connection to a 220V~/50Hz power line
O1
Main pump output
Maximum current capacity: 3,15A or 700W
O2
Relay output
–
potential free output, switch relay
Maximum current capacity: 8A
- Relay off – S1-S2 contacts closed
- Relay on – S2-S3 contacts closed
O3
Relay
-
current output 220V~
Maximum current capacity: 8A
O4
220V~network power outlet,bridged inside the controller.
This output can be bridged externally with the switch relay input,
achieving this way a switchable power supply for controlling, for example, a three way valve.
T1, T2, T3, T4
NTC10k temperature sensor inputs
Chart 1. Controller input and output description
When connecting devices to the controller's outputs, it is important to remember that outputs marked O1 and O3 are voltage outputs which can be
connected directly with an external device. O2 output has a potency-free character and should be connected in series between the power source and the
external device.
ATTENTION!!! Descriptions of connecting devices to the controller in particular installation types is presented in paragraph 6 (Controller
systems).
