7.4 Setting the time bands
Note: this screen is visible if “scheduler ON/OFF” has been enabled
(see the enable scheduler screen).
Set the intervals for the operation of the humidi er over a 24h period
(one day):

By setting the “daily” and “variable set point” time bands, steam production
can be programmed according to the needs of the utility.
Note:
during the “OFF” time band, the humidi er is NOT actually o , but •
rather steam production is temporarily disabled, even when setting
manually;
the “daily” time bands have priority over the “variable set point” bands. •
For example, setting P4 each Monday (humidi er o ), parameters
Z1, Z2, Z3, Z4 (di erent set point values) will not be observed, as the
humidi er is not programmed to operate on that day.
