Page 4: Description Of The Controller
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. -
Page 5: Using The Controller
Using the controller Switching the controller on After connecting the controller to a power source, the controller will switch on in a standby mode. LCD display will become half lit, and the screen will show the current time. When the controller is in a standby mode, it can be switched on with this button . - Page 6 Next, using the buttons , select the option „Installation type selection”, confirm the selection by pressing . After entering the mode of selecting the installation type, the screen will display an installation type diagram, along with its number, as shown in picture 4. Scheme 4 Pic.

Page 9: Description Of Control Parameters
If you don't want to change the current language version, return to the main menu by pressing . In order to return to the main screen, press Description of control parameters ΔT1 – Basic control coefficient. This parameter determines the condition for switching the collector pump on and off. If the sum of parameter ∆T1 and the temperature in tank T2 exceeds the value of temperature in the tank located on T1 collector, the collector pump will switch off. -
Page 10: Installation Systems
Controller's installation systems Basic system of Hot water heating system – controlling the solar collector pump, circulation pump and the boiler Controlling the collector pump P is done with the use of temperature sensor T1, and sensor T2, placed in the tank. When the sum of temperature T2 and the control coefficient ∆T1 exceeds the value of temperature T1, the pump switches off, and will remain switched off until the sum of T2 + ∆T1 falls below the value of T1. - Page 11 Hot water heating system – controlling the solar collector pump, circulation pump and the heater. Controlling the collector pump is analogous to that in the system no. 1 described in paragraph 6.1. Controlling the circulation pump is analogous to that in the system no.
- Page 12 A system of two heaters , allowing for additionally heating the return circulation with solar energy Controlling the collector pump is analogous to that in the system no. 1, described in paragraph 6.1. Controlling valve U is done with the use of sensors T2 and T4, and an auxiliary control coefficient ∆T2.
- Page 13 A system of two solar heaters, with heating priority for heater B Heating using heater B collectors is analogous to that in the system no. 1, described in paragraph 6.1. When a given temperature is reached in heater B, or temperature T2max is exceeded, the controller automatically starts heating water in tank A, switching on output O2 and redirecting valve U in the direction of heater A.
- Page 14 System of heating hot water with solar collectors. Additionally, a system activating the heating of hot water after the boiler achieves a required temperature Controlling the collector pump is analogous to that in the system no. 1, described in paragraph 6.1Pump K operates with the use of temperature sensors T3 and T4, and an auxiliary control coefficient ∆T2.

Page 15: Alarms
Sensors' error alarm The controller features temperature sensors' connection control and short circuit control. If a sensor becomes damaged, a cable is broken or the sensor is disconnected, the controller will alert you about this. During the alarm, all outputs are disconnected, and additionally, when the controller is displaying the main screen, sound alarm signalization is on.
