2.5.2.4. Summer night cooling
Summer night cooling function is intended for energy saving during the summer
season: by utilizing the outside chill of night hours, it is possible to cool down
heated rooms, i.e. to remove excessive heat that accumulated in the room during
day hours.
Summer night cooling function can start at night (from 00:00 h to 06:00 h a.m.)
at any time, even when the air handling unit is not working and is in standby mode.
User can set indoor temperature, at which this function starts and stops.
When this function is active, the current ventilation level is switched to the
maximum ventilation intensity (100 %) and ventilation is performed only by means
of fans, i.e. at that time neither the air cooling nor the energy recovery functions
operate.
Summer night cooling function has an operating priority over the fol-
lowing functions: outdoor compensated ventilation and the air quality
function.

2.5.2.5. Minimum temperature control

In winter time the minimum temperature control function forcibly reduces the sup-
ply and extract air flow set by the user when the heater capacity available in the
unit is insufficient and/or heat recovery does not ensure minimally possible tem-
perature supply to the room. The user can set a separate supply air temperature
value so that when that value is not achieved, the intensity of the ventilation unit
starts to be reduced automatically. The air flow may be reduced to the minimally
possible ventilation intensity of 20 %.
During the summer, when the air handling unit provided with cooler, this func-
tion according to the same user-set value limits the cooling capacity, thus ensuring
the minimum possible temperature supply to the room.
In ventilation intensity control, this function has top priority over "Out-
door compensated ventilation" and "VAV" functions.

2.5.2.6. Override function

Override (OVR) control of the unit can be performed by the external contact
(see Picture 1.3 b) or device (timer, switch, thermostat, etc.). The received signal
from the outside activates the OVR function, which ignores the current operation
modes of the unit and performs one of the selected actions listed below:
• switches off the air handling unit;
• switches over the unit to operation according to the mode "Comfort1";
• switches over the unit to operation according to the mode "Comfort2";
• switches over the unit to operation according to the mode "Economy1";
• switches over the unit to operation according to the mode "Economy2";
• switches over the unit to operation according to the mode "Special";
• switches over the unit to operation according to the weekly schedule.
