6. ACTIVATING THE ECONOMICAL VENTILATION

Unlike the normal reading that measures the maximum concentration of the module line
detectors, this mode carries out two measurements: maximum and minimum among all
detectors of the same line, taking the average of the two as a reference point. In this way,
it reduces the number of times the ventilation is activated, with the subsequent electrical
energy saving and without loosing efficiency, as regards to protecting the installations.
To access this mode:
1. Make sure the module line is in OFF position (disconnected)
2. Press VENTILATION MODE
for a few seconds
Now the economy ventilation mode is activated and you can connect the module line
again.
To deactivate the Economy Programme:
1. Make sure the module line is at OFF position (disconnected)
2. Press VENTILATION MODE
on the display for a few seconds
