II.2. Setting up
The unit must be laid on a sufficiently rigid and flat surface (use vibration mounts if necessary). For the HVAC connection,
select duct sections based on dimensions of the flexible bands that should be properly stretchedhe ducts should be insulated
and the first accessories should be at 2.5 times the diameter (Tee elbow ...). Install the unit such that bad weather or ambient
temperature cannot damage the internal items of the unit during installation as well as when used later
Provide a siphon on each condensate drainage pipe. A siphon can only be used for one drainage system.
Note: the siphon must be connected in accordance with Best Practices in order that the condensates are
removed as efficiently as possible.
The height H must be at least equal to the maximum internal negative pressure of the unit (Dp in mm).
Example : Dp = 500 Pa @ 50 mm CE
H > 50 mm 2H > 100 mm
The unit placed outside must always be fixed to the floor of the support frame, so that it can not move or fall (take into account
the force of the wind). Also provide a roof (DPE) as well as awnings rain (AGE) if necessary (optional).
II.2.a. Connection of separate modules
The connecting brackets between boxes are prefixed on each of the modules of EXAECO.
If necessary, wedge the boxes so that the amounts of these are perfectly parallel.
Bring the modules together and secure them by tightening the bolts (provided) with the mounting brackets (M6 x 16). Also
tighten the M8 X30 bolt (supplied) on the chassis.
II.2.a.1.Climatic module (version ELITE)
Connect the 2 quick connectors and the clear tube for the LOBBY versions.

IV.4. Wiring and operation of rotative exchanger
Rotative exchanger is factory wired
CORRIGO controller drives automatically the bypass thanks to programmation and sensor mounted in standard on EXAECO
units.
In winter: when heat is needed, The rotative exchanger starts to recover maximum of calories. This recovery is associated with
3 ways mixed dampers If it is not enough to reach the temperature setpoint, hot battery starts running.
En été :
COLD RECOVERY : if outside temperature is higher than inside temperature and cold is needed , The rotative exchanger
starts to recover maximum of calories. This recovery is associated with 3 ways mixed dampers. If it is not enough to reach the
setpoint, cold battery starts running.
FREE COOLING : if outside temperature is lower than inside temperature and cold is needed , The rotative exchanger stops to
bring directly outside fresh air. This recovery is associated with 3 ways mixed dampers. If it is not enough to reach temperature
setpoint cold battery starts running.

When activated, the 3-way module is completely recycled. Hot and cold outputs are active. The recirculation function is set as
standard from 05:00 to 07:00. It can be actuated either by the clock 5 or by an external free voltage contact connected between
the terminals 47-48. If the Night Cooling function is active, then it will have priority over recirculation.
For LOBBY® EC versions, a 24V output (to be relayed) is available between terminals 69-70 to force the opening of the
dampers during the recirculation period. To wire independently of the Night Cooling output
The functions below will not be active if the control panel is associated with a DIVA or QUATTRO option
TEMPERATURE FUNCTION OF MODULE FEE
In winter : When you are in hot demand, the 3-way module closes appropriately until the maximum recycling (minimum fresh
air flow rate can be adjusted (see chapter V.6.d)) to recover a maximum of calories. This recovery is associated with the rotary
exchanger. If it is not enough to reach the temperature setpoint, the hot battery goes into action
In summer :
COLD RECOVERY: If the outdoor temperature is higher than the indoor temperature and when there is a cold demand, the 3-
way module closes appropriately until the maximum recycling (minimum fresh air flow rate can be adjusted to This recovery is
associated with the rotary heat exchanger If it is not enough to reach the temperature setpoint, the cold battery goes into action.
FREE COOLING: If the outdoor temperature is lower than the indoor temperature and you are in cold demand, the 3-way
module opens appropriately until all fresh air to recover a maximum of calories. This recovery is associated with the rotary
exchanger. If it is not enough to reach the temperature setpoint, the cold battery goes into action
CO2 FUNCTION OF THE FEE MODULE: The 3-way module also manages the indoor air quality. In the case where the CO2
level in the building is higher than the setpoint then the signal imposing the most fresh air (temperature or CO2) will have
priority.

IV.11. Night Cooling (Surventilation nocturne)
This function is used during summer to cool down buildings during nights with outside cool air. It decreases the cold needs
during days. Night Cooling function runs only from 00:00 AM to 7:00 h AM. During Night Cooling, hot and cool outputs are
locked on 0V. Exchanger runs only with fresh air. At the end of Night Cooling period heating is blocked to 0V during 60
minutes.
Start conditions: customizable in chapter V.5.b.2
oOutside temperatures are higher to 22°C during the day.
oClocks are setted in LS or stopped during 00h00 and 07h00.
oOutside temperature is lower than 18°C during Night Cooling period
oOutside temperature is higher to 10°C during Night Cooling period
oRoom temperature is higher to 18°C
During Night Cooling period fans are running 85% of their capacity. This speed is adjustable (see chapter V.5.b.2)
For LOBBY versions, a 24V output (to relay) is available between 22 and DO7 terminals to force the opening of damper’s
zone during Night Cooling period.
