System Modes:
› Stand-by;
› Building protection;
› Economy;
› Comfort.
In Stand-by mode
the system is shut down for a permissible period (based on the Stand-by mode blocking function settings).
The Building protection mode
is designed to protect premises against moisture accumulation.
The system operates at speed 1. Based on manufacturer’s parameters (by default) this mode controls the temperature (the desirable one is indicated),
but, if necessary, it can be switched off, i.e. to activate the energy saving mode. Also, if necessary, full recirculation function is activated. (ADJUSTER
› USER SETTINGS › BUILDING PROTECTION MODE TEMPERATURE or USER › MENU › SETTINGS › BUILDING PROTECTION).
After activating the energy saving mode, temperature is maintained only by the heat exchanger. It will seek to maintain the current temperature in the
room; however, if the supply air temperature falls below the minimal supply air temperature level, heaters will be activated and they will maintain a
temperature one degree above the minimum. Also, if the supply air temperature rises above the maximal supply air temperature level, coolers will be
activated and they will maintain a temperature one degree below the maximum.
Economy mode
is designed to save energy when people are absent from the premises. The system operates at speed 2. Based on manufacturer’s
parameters this mode controls the temperature maintaining (the desirable one is indicated), but, if necessary, it can be switched off, i.e. to activate the
energy saving mode. Also full recirculation function is activated. (ADJUSTER › USER SETTINGS › ECONOMY MODE TEMPERATURE or USER ›
MENU › SETTINGS › ECONOMY MODE).
Comfort mode
is running when people are present in the premises. The system operates at speed 3. In this mode the temperature is always main
-
tained – it is set in the main window (ADJUSTER › VENTILATION CONTROL or USER › SET POINT).
System modes are changed by the following functions (indicated in a sequential order):
› Weekly Schedule;
› Switching on is activated from an external contactor;
› Manual mode selection;
› Holiday Schedule;
› Stand-by mode blocking.
Based on the Weekly Schedule the system decides in what mode it will be operating; however, the user may change it manually. The system informs
when the next mode change is scheduled. After power loss the mode is selected based on the Weekly Schedule; however, if it is not set, the mode
that was set before the power loss will be activated.
The user may change modes even when the switching on is activated from an external contactor. The only case when it is not possible – active period
of Holiday Schedule of which the system informs and which must be changed to avoid blocking.
Stand-by mode can be blocked by selected parameters. If at least one of the above functions changes its mode into Stand-by mode, it must be
checked whether this mode is not currently blocked. If it is blocked, the previous mode shall be activated.
The function order is provided below.
