BUILDING PROTECTION
mode for 5 minutes so that the actual temperature data is available. The tem-
perature is checked after purging. If it is not suitable, the unit returns to STAND-BY mode;
• Outdoor temperature is higher than the set outdoor temperature;
• Exhaust air temperature is higher than the set temperature;
• Exhaust air temperature is higher than the outdoor temperature by at least 2 °C;
• Summer.
If all conditions are met the unit starts operating in
COMFORT
mode (without temperature maintaining). The main window shows that the Night cooling
function is active. When it is active continuously, the deactivation conditions are checked:
• Time does not correspond to the start/end interval;
• Exhaust air temperature drops below the set temperature;
• Outdoor temperature drops below the set temperature;
• Mode other than
COMFORT
was switched or the unit has been shut down.
If at least one condition is met, the unit switches off the Night cooling function and it switches to the mode that was on prior to activating the func -
tion.

types of signals:
• Not used;
• Upon pressing a button the selected system mode is activated. After receipt of the first impulse the function is activated, and after second
impulse – deactivated;
• On/off; selected system mode is activated. The mode is active while the contactor is on;

contactor.
The function indicates a type of a signal to be sent to the input and components controlled by it. Possible combinations of signal types and func-
tions:
• Not used
;
• On/off – selected fan speed combination is activated. Function is on when contactor is on;
• Button click – selected fan speed combination is activated. Function is activated when it receives an impulse. It is deactivated when it receives
the impulse again;
• On/off
– Boost ventilation function is controlled. Function is on when contactor is on. If the boost ventilation function is not terminated by means
of this function within the boost ventilation time limit, force shutdown is used after the time expires;
• Button click – Boost ventilation function is controlled. Function is activated when it receives an impulse. It is deactivated when it receives the
impulse again;
• If the boost ventilation function is not terminated by means of this function within the boost ventilation time limit, force shutdown is used after
the time expires.
It is also indicated whether boost ventilation will be activated or combination of fan speeds is preferred, i.e. it is possible to indicate preferred supply
and extract air fan speeds individually.
