The use of a normal operation schedule allows the fans to be forced to the normal operation setpoint without

management. This can be useful, for example, when you want to purify the atmosphere between two periods of
occupancy.
13.6. Recommendations for time schedule settings in the ECO et MAC2 versions
In the ECO or MAC2 versions it is necessary to distinguish:
■
The period of occupancy of the building (or zone) to which the normal operation will be linked
■
The period of occupancy of the building (or zone) to which the reduced operation will be linked.
The example setting below corresponds to an occupation of the zone served by the ventilation unit between 07:00 and
19:00. During this time, the ventilation unit runs in normal operation to ensure the required comfort and air quality. The
rest of the time, the ventilation unit runs in reduced operation to limit energy consumption. If the conditions for
activating the night cooling function are met, it will operate during the set time frame (00:00 - 07:00 factory setting).
14. Maintenance and fault diagnosis
14.1. General
Reasons for malfunctions are either:
■
Outside the machine:
■
special air volume network, presence of regulated registers, etc.
■
BMS/CTM sending the wrong setpoints
■
Inside the machine:
■
probes, sensors, actuators, wiring, etc.
In most cases, the fault will be visible on the machine (presence of an alarm), but this does not necessarily mean that the
cause is in the machine itself and prior checks must be carried out before diagnosis.
