Standard Mode Functionality
Power Mode
All curtain(s) are given a continuous close signal. Inlets are controlled by static
pressure (if used). All outputs that are allowed to operate in Power Mode turn on
and off per screen 4 trying satisfy their sensors assigned in Screen 13.
Natural Mode
Main Curtain Range- The Main curtain range is defined in the Outputs and
Temperature screen (Screen 4) and has a default setting of + or - 1.5 degrees F of
the set temperature. Once the Control has made the full transition from Power to
Natural mode (or Tunnel to Natural), each main curtain's control sensor will
either open or close the main curtain(s) to try to keep the sensor's temperature
within the Main curtain range. If the curtain's control sensor temperature goes
above the range then the curtain will open. If the curtain's control sensor
temperature goes below the range then the curtain will close. The amount the
curtain moves is based upon how far the curtain's control sensor(s) is from the
AVERAGE of the Main curtain range. If the curtain's control sensor(s) goes
more than 8 degrees F ABOVE the AVERAGE of the Main curtain range, the
curtains will be given a continuous open signal until the temperature returns to
within the Main curtain range. If the curtain's control sensor(s) goes more than 8
degrees F BELOW the AVERAGE of the Main curtain range the curtains will be
given a continuous close signal until the temperature returns to within the Main
curtain range or until the Control returns to Power Mode. The control returns to
power mode when the main curtain(s) reach the first opening position (see
Natural to Power Mode transition).
Time Between Curtain Movements
The Time between curtain movements is the amount of time the control will
wait after an opening or closing of the main curtain(s) before checking the
temperature again and doing another open or close movement. The default
time between curtain movements is 2 minutes. The amount time between
curtain movements can be set between 1 minute and 5 minutes. The time
between curtain movements is set in Screen 14, Curtains tab.
Rate of Curtain Movement
The Rate of Curtain Movement is the amount the control will either open or
close the curtain(s) during a curtain movement. The actual amount of curtain
movement is calculated by taking the Rate of curtain movement and
multiplying by the number of degrees the curtains control sensor is from the
AVERAGE of the Main Curtain Range. For example, if the Rate of curtain
movement is 1.2 inches per degree F, the AVERAGE of the Main Curtain
Range is 74.0 degrees F and the curtains control sensor is reading 76.0
degrees F then the control will open the curtain 2.4 inches (1.2 x [76-74]).
The default Rate of Curtain Movement is 1.2 inches per degree F and can be
set between 1 in and 4 inches per degree F. The rate of curtain movement is
set in Screen 14, curtains tab.
All Outputs that are allowed to operate in Natural Mode turn on and off per
the Outputs and Temperatures screen (Screen 4) trying to satisfy their
sensors assigned in the Setup-General screen.
