System 2000 AUTO TEMP 7
6.2.2.3. Automatic Temperature Reduction or Ramping
The System 2000 Auto Temp Controller can easily be programmed to
automatically reduce temperature on a day to day basis. Each room can
selectively have its own ramp. All that is required from the operator is
to enter the number of days for the ramp and then an ending target
temperature. The system uses this information along with the current
system Target Temperature to calculate a new target temperature for
each day. Note that if at any time during a ramp period the
temperature in the house seems to be too high, or too low, all that must
be done is to change the current target temperature (with the Target
Temperature arrows) and the ramp will continue from that point.
6.2.2.4. Timer Period
The System 2000 Auto Temp controller has a built-in cool stage timer
for each room. This timer may be set for a period of from 1 to 15
minutes. The timer is most often used as a 10 minute timer. Any cool
stage may be set to operate on a time as well as temperature basis via
this timer.
6.2.3. Programming the Stages
The System 2000 Auto Temp controller is an integrated 12 stage controller with a built
in timer. Each of the 12 stages can be programmed to be either a heat or a cool stage.
What's more, any cool stage can be placed on a timer in addition to standard
temperature-based operation. Each stage may operate off any combination of 7 sensors.
Each stage is programmed for temperature utilizing an offset/differential method. (See
Offset and Differential earlier in this manual.) Each cool stage can be placed on the
system timer. This is a programmable timer which may have a period of from 1 to 15
minutes, and any percentage from 1 to 100 percent. The stages are programmed in the
Program Features section of the controller
6.2.4. Setting the System Clock
The system clock is a battery-backed up 24 hour clock (12 hour with a.m. and p.m.)
Several functions operate using this clock--these include artificial lighting, and feed
control. It should be necessary to set the clock only once except to accommodate
standard/daylight savings time. The System Clock is located in the Programming
Features.
While setting clock the controller will ask you for several bits of information. this
information is used in calculating Sunrise, and Sunset. Thus it is important to be as
accurate as possible in setting the clock. Information the clock needs to operate properly
includes: Year, Month, Day, Hour, Minute, Time Zone, and the Latitude and Longitude
of the building the controller will be operating. (Latitude and Longitude is entered in #
of Degrees, # of Minutes, and # of Seconds.) It is important to be as accurate as possible
to ensure accurate controller operation throughout the year. The time zone code may be
found on the chart at the back of this manual. Latitude and Longitude can be obtained
from a topographical map, or the geological survey office in your area.
6.2.5. Saving and Restoring Levels
The Auto Temp has a mechanism that allows you to save the setup of the machine once
it has been programmed for a particular crop, and setup a completely different program
