5.8 Time bands

The operation of all the devices in the system can be controlled based on set time bands, managing the
status (STANDBY / ON) and if necessary setting a common set point.
The following are available:
• 2 common time bands for the first five days of the week (Monday-Friday)
• 2 common time bands for the last two days (Saturday-Sunday).
Information
• Parameter En04 (Use clock and time bands) must be set to 1 (default value).
• In the periods when the system is off, none of the e-drofan units can be started, not even using the
acqua or e-droset terminal, as the µAM keeps all the devices OFF by setting the status every minute.
• In the periods when the system is on, the individual e-drofan units can be switched off, as the µAM does
not set the ON status.
• In any case, sending the change in status from the µAM (POWER button or automatically when managed
by time bands) cancels and replaces the previous status for all the devices connected.
