We recommend fitting a switch on the CO2 sensor to enable and disable it.
The CO2 sensor commands lapse in the following conditions:
a.
for disabling the weather functions by means of a dedicated switch;
b. When an emergency or weather event occurs (depending on the situation, the command is
inverted or left in the state it was in).
8.4.2 Thermostat
8.4.3 CO2 sensor
NOTE FOR IMPULSE OPERATION:
When using manual commands, the drive on the actuator can be stopped by
pushing and releasing within 1 second the push button for movement in the
opposite direction (e.g. when opening, pushing the close button).
When the actuator is stopped, to select the new direction of movement, simply
push and release
within 1 second t
he push button that relates to the new action
required.
NOTE
The control unit mod. C-SV IB 4A/8A is equipped with a push button panel for
natural ventilation commands (see picture aside).

2. CLOSING
A closing command sent to the actuator by manual commands, does not result in any type of signal.
The close command ceases:
a.
When the maximum stroke time of 180 seconds is reached (impulse operation) or when the manual button is released
(dead man operation).
b.
When the reset button is pushed (the drive command ends).
c.
Impulse operation: the drive stops when the open button is pushed and released within 1 second.
d.
for the occurrence of an emergency or weather event (as the case may be, the drive changes its direction or performs an
emergency opening/closing)

You can connect a thermostat which sends an open or close signal to the control unit, accord
-
ing to the temperature threshold set (see diagram 5 on page 50).
Enabling of the thermostat blocks the manual commands. However, Emergency, CO2
and weather (rain, wind) signals and CO2 sensor signals still enjoy priority.
We recommend fitting a switch on the thermostat to enable and disable it.
The thermostat commands lapse in the following conditions:
a.
for disabling the weather functions by means of a dedicated switch;
b. When an emergency or weather
or CO2
event occurs (depending on the situation, the com

mand is inverted or left in the state it was in).
Thermostat TH
CO2 sensor
You can connect a CO2 sensor which sends an open signal to the control unit, if the threshold
set for the presence of carbon dioxide is exceeded (see diagram 5 on page 50).
Activation of the CO2 sensor blocks the manual commands, and enjoys priority over
the thermostat commands. However, emergency and weather (rain, wind) signals still
enjoy priority.
