Day Number
The intention is that the day # is the age of the animals whose environment is being
controlled. Day # 0 does not exist. Negative days (down to - 7) are allowed.
Changing the day # in any screen that shows the day number, will change the day #
in all the other screens that show the day #.
Digital Input
Digital Inputs can consist of the following:
1. Water meter
2. Feed scale
3. Air speed sensor
4. Low water pressure switch
5. Max feed run time Input
6. PDS flush feed back
Event
This term applies to the time clock Outputs. An "event" is an "on at" time combined
with an "off at" time.
Mode Sensor(s)
The concept of Mode Sensor(s) is essential to the understanding what makes the
Control change from one mode to another. The Mode Sensor(s), of a currently
operating mode, determines when the Control will leave that mode. As an example,
while in the Power Mode, the Power Mode Sensor(s) determines when it's too hot to
stay in the Power Mode (i.e. above the tunnel "on" temperature). Because of this, it
converts to the Tunnel Mode (assuming there is no Natural Mode) at the tunnel "on"
temperature. It comes back to the Power Mode from the Tunnel Mode, when the
Tunnel Mode Sensor(s) say it's too cold to stay in the Tunnel Mode (i.e. below the
tunnel "off" temperature).
Natural Mode
Natural Mode requires the house to be equipped with Curtains in the side walls that
are powered by Drive Units (Curtain Machines). The Control converts to this mode
of operation when the temperature(s) inside the house raise to a level that the Fans of
the Power Mode can't keep the temperature(s) under control. While in the Natural
Mode of operation, the Curtains are opened or closed, as required, to control the
temperature(s). This mode of operation generally happens during moderate weather.
