or the pre-set temperature has been reached, the fan will enter automatic operation mode.

NOTE
Information about current fan operation mode is saved in the controller memory 6 seconds after the last
parameter change.

CONTROLLER OPERATION MODES
Regardless of the selected profile, the controller may operate in three modes: heating, cooling or automatic
heating/cooling. In Service settings/Mode selection submenu the user configures particular mode. The user may select
one operation mode - by selecting Heating or Cooling or allow manual mode change from the main screen view - by
selecting Manual heating/cooling.
Heating
Once this mode has been selected, when the controller detects that the room temperature is lower than the pre-set value
(setting in Temperature settings submenu), it activates the fan and opens the valves in order to raise the temperature.
When the room temperature reaches the pre-set value minus user-defined value (setting in Service menu/Temperature
settings), the controller gradually starts decreasing the fan speed and closing the valve.
Once the pre-set room temperature has been reached, the fan is disabled and the valves are closed ( fan automatic mode
is active).
Cooling
Once this mode has been selected, when the controller detects that the room temperature is higher than the pre-set
value (setting in Temperature settings submenu), it activates the fan and opens the valves in order to decrease the
temperature. When the room temperature drops to the pre-set value plus user-defined value, the controller gradually
starts decreasing the fan speed and closing the valve.
Once the pre-set room temperature has been reached, the fan is disabled and the valves are closed ( fan automatic mode
is active).
Automatic heating/cooling
The heating mode changes automatically depending on the current room temperature and the pre-set value.

CONTROLLER FUNCTIONS
During standard controller operation, the display shows the main screen. By pressing menu button the user may configure
the controller functions.
Due to the controller complexity (a wide range of configurable parameters), the controller menu is divided into the main
menu and the service menu secured with a 4-digit code. The main menu includes basic controller parameters such as
operation mode, pre-set temperature setting, main screen view etc.
