8.2.3 Summer night Cooling
The lower temperature at night is utilized to cool down
the building structure. This reduces the cooling load
during the first hours of the day. If a cooling unit is
installed, its in-operation hours will be minimized, thus
offering savings. If no cooling unit is installed, a certain
cooling effect will still be realized.
When summer night cooling function is activated, the unit
fans operate at high speed, with a supply air setpoint of
10°C, from the preset time until the conditions necessary
for stop are satisfied.
The extra temperature zone (Xzone), if any, will obtain
the same supply air set point if summer night cooling is in
operation.
Conditions to be met to start summer night cooling at the
preset time:
• The extract air temperature should be higher than the
preset value
• The extract air should be at least 2°C warmer than the
outdoor air.
• The outdoor temperature should be above the preset
value.
• Heating has not been required between 12.00–23.00
hours.
• The unit must not operate in the high speed mode or
be stopped from an external source or manually from the
hand-held micro terminal.
Conditions to be met to stop summer night cooling at the
preset time:
• The extract air temperature drops below the preset
value.
• The outdoor temperature drops below the preset value.
• Switch clock or external input calls for high speed.
• The extract air is less than 1 °C warmer than the outdoor
air.
The function starts once per set time period.
