COLLECTOR SCHEDULE
After the collector schedule has been activated, the heat pump does not work for the collector pump, which becomes the only
source heating water in the tank.
Additionally, it is possible to set parameters in such a way that when the function is activated, neither the heat pump nor the
pump of the additional heat source of the solar collector will work.
For example, when the minimum operating temperature of the additional heat source is set to 40°C, and the pre-set temperature
is 30°C, the current tank temperature is below the pre -set value and then no heat source will be enabled.
LEGIONELLA SCHEDULE
The option allows you to fix a schedule for the hot water system thermal disinfection process so as to eliminate any
microorganisms from the system. Days and hours are selected in the same manner as in the
WEEKLY SCHEDULE function.
CIRCULATING PUMP
The function allows the circulating pump to be switched on/off. Before it is activated, its working time and breaks should be
determined. An additional advantage is the possibility to fix a schedule. Its operation is similar as to that of the
WEEKLY SCHEDULE
option.
DETAILS SCREEN
Launching the details screen allows you to view readouts from the temperature sensors, the condition of particular devices, as
well as general information.
SCREEN SETTINGS
This function is to set the screen brightness while operating the controller and to mute it.
SOFTWARE INFORMATION

ETHERNET MODULE
The Internet module is a device for remote control of the system ’s operation. The User can control the status of all the devices in
the installation via the screen of a computer, tablet or mobile phone. Apart from the possibility to preview the temperature
sensors, the user can change the preset heat pump temperature. The module can also operate a solar collector.
After activating the Internet module and selecting the Registration option, the user generates a code needed to register the
controller via emodul.eu. After selecting the DHCP option, the controller will automatically download the parameters from the
local network, among others: IP address, IP mask, gate address and DNS address. In the case of any problems with downloading
the network parameters, it is possible to set these parameters manually. The method of obtaining the local network parameters
has been described in the operating instructions of the Internet Module.
