VENTILATION MODES

If the control unit is programmed in Normal ventilation; Ventilation is activated by the
module line when any of the installed detectors reaches a CO concentration equal or
higher than the level programmed, and after confirming it by a second measuring.
Same way, ventilation is deactivated when the highest value is below the ventilation level
programmed, and after confirming it by a second measuring.
If the control unit is programmed in Economical ventilation, Ventilation is activated by
the module line if, after doing the average reading between the higher and lowest values
detected, the level would be equal or higher than the one programmed. In addition, a
second measurement would be needed in order to confirm. Then, ventilation operations get
reduced, saving electrical energy with no loss of effectiveness regarding place is protection.
Same way, ventilation is deactivated when the average reading between the higher and
lower values detected would be lower than the level programmed, and after verifying with
a second measurement.
The programming of the Ventilation Mode is cyclic (automatic -> manual -> disconnected
-> automatic)
• Automatic ventilation mode: This is the mode pre-set at the factory. The AUTO Led will
light up to confirm this status.
• Manual ventilation mode: By pressing VENTILATION MODE
once, the manual
ventilation will be activated and the ON Led will light up to confirm this status.
• Disconnection mode: By pressing VENTILATION MODE
again the ventilation will
disconnect and the STOP Led will light up to confirm this status.
When the module line reaches the level programmed, the VENTILATION LEVEL Led will
light up.
IMPORTANT!. To activate the ventilation of a module line, this has to measure, during two
cycles (5 min) a CO concentration that is equal or greater than that programmed. The same
conditions must exist to deactivate, but in this case, the concentration measured by the
module line should be lower than that programmed.
In equipments with double speed ventilation, operation is the same, but applicable to the
two levels programmed.
