 - 

IV.c.3) Holiday Mode 

After the user activates Holiday Mode, the pump operates when one of the following conditions is met: 
The  collector's  temperature  increases  to  the  overheat  temperature  value  (SERVICE  MENU>  Solar 
Collector  >  Overheat  Temperature)  reduced  by  the  value  of  the  parameter  Delta  Holiday  (SERVICE 
MENU> Solar Collector > Delta Holiday). When this condition is met, the pump is activated to cool down 
the collector. The pump is deactivated after the temperature is reduced by 5°C. 
 If the  collector's temperature is lower than the tank's temperature  – the pump is activated to cool 
down the tank and will operate until the collector's and the tank's temperatures are level. 
 

IV.c.4) Anti-Legionella 

This function is only active when an additional device is connected (found under the function Peripherals 
in the Service Menu and then activated). Thermal disinfection involves increasing the temperature to 
the required disinfection temperature in the tank – this reading is taken from the upper sensor in the 
tank (in the case of using an optional sensor, the user should make sure that this sensor measures the 
temperature in the upper part of the tank because this is the priority sensor for this function). This is 
to eliminate the Legionella pneumophila bacteria that reduce the body's cell immunity. These bacteria 
often multiply in tanks with stagnant hot water (at an optimum temperature of 35°C). After the user 
activates this function, the tank heats up to the defined temperature (SERVICE MENU > Peripherals > 
Heater  >  Anti-Legionella  >  Anti-Legionella  Temperature
)  and  maintains  such  a  temperature  for  the 
time of disinfection (SERVICE MENU > Peripherals > Heater > Anti-Legionella > Anti-Legionella Time
and then returns to the regular operation mode. 
From the moment of activating the disinfection, the temperature of disinfection needs to be reached in 
no longer than the time defined by the user (SERVICE MENU > Peripherals > Heater > Anti-Legionella 
> Maximum Anti-Legionella Time
), otherwise this function is deactivated automatically. 
 

IV.c.5) Manual Operation 

Using this function, the user may manually (by pressing the ‘Menu’ button) activate and deactivate the 
following to control the installation's equipment: 
- Solar Pump, 
- Second Solar Pump or Switching Valve, 
- Peripherals - Additional Device (voltage-free contact e.g. for firing up the pellet boiler). 

 

IV.d) Timer 

Using this function, the user adjusts the current hour for regulator operation. 
 

IV.e) Date 

Using  this  function,  the  user  adjusts  the  current  date.  The  correct  adjustment  of  date  and  hour  is 
necessary to calculate energy in a proper manner. 

 

IV.f) Ethernet Module 

 
NOTE   

Control of this type is possible after purchasing and connecting an additional  ST-500 control module 
(which is not added to the controller as a standard). 
 

The Ethernet Module is a device for enabling remote control over the collector's operation via 

the Internet or a local network. On the home computer screen, the user controls the status of all the 
solar installation devices and the operation of each device is presented in the form of an animation. 
 

After activating the Internet module and selecting the DHCP option, the controller automatically 

downloads the following parameters from the local network: IP Address, IP Mask, Gateway Address and 
DNS Address. In the case of any problems with downloading the network parameters, it is possible to 
adjust these parameters manually. The method of obtaining the local network's parameters is described 
in the manual for the Internet Module. 
 

The function Reset Module Password may be used when the user  changed the factory user's 

password to his own password on the login page. When the new password is lost, it is possible to return 
to the factory password after resetting the module password.
