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 humidifi er over a 24h period
(one day):
time band ON OFF
P1 P1-1 09:00 13:00
P1-2 14:00 21:00
P2 14:00 21:00
P3 always ON
P4 always OFF
Parameters P1 to P4 can be used set how many times steam production
is enabled/disabled over a 24h period:
P1 Two daily ON time bands
0 24h

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 humidifi er is NOT actually off , 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 (humidifi er off ), parameters
Z1, Z2, Z3, Z4 (diff erent set point values) will not be observed, as the
humidifi er is not programmed to operate on that day.
