Noticing an Alarm
"Noticing" an alarm is a very important part of using the alarm system. By pressing
the alarm button, you can tell the Control that you have "seen" the alarm message.
The first press of the alarm button "notices" the alarm message at the top of the alarm
screen. Each additional press of the alarm button "clears" the first alarm and "notices"
any additional alarm(s), one at a time.
Offset
The term "offset" applies to the Set Temperature and Minimum Ventilation Timer
curves only. If you manually adjust either the Set Temperature or the Minimum
Ventilation Timer settings, while the curve is on, you create an "offset" to that curve
relative to it's "curve value". The "curve value" is not changed. (see the "curve
value" definition above.) The curve value is shown as a convenience so that you
know what you have to change it back to in order to get back on the actual curve's
table listing. While an "offset" is in effect, the parameter of the curve is still modified
versus time. However, the actual parameter value is the "curve value" modified by
the "offset".
Power Mode
The building is closed up except for Inlets (usually Baffle Doors) which are powered
open and close in order to control the static pressure level. In some cases Gravity
Inlets are used where the static pressure is not controlled directly. The only
ventilation provided is due to Fans mounted in the end or side walls. This mode of
operation generally happens when the outside temperatures are somewhat lower than
the set temperature.
Program
A "program" is a complete set up of all the screens of a Control. In the main menu
Program Tab, six different "programs" can be saved and later activated. This can be
very convenient when it is desired to change the set up at different points during the
grow out, barn cycle, or times of the year.
Set Temperature
The set temperature is another very important, basic, concept. All temperatures are
referenced to the set temperature. When the set temperature is adjusted either
manually, or because the set temperature curve is on, all other temperature settings
move up or down by the same amount. For instance, even though you program an
actual temperature for each Fan to come on and off, when you change the set
temperature, those Fan's on and off temperatures are adjusted by the same amount
you changed the set temperature.
