4.0 degrees below Target Temp and has reached a high of 1.0 degrees
above Target Temp.
Example of Sensor 1's 2nd Display:
-S1 Avg. from target
-0.4 f 14.37 hours
This means that Sensor 1 has averaged 0.4 degrees below Target Temp
during the past 14.37 hours.
Calibrate Sensors
If at any time you notice that the sensors are not reading right, you can
calibrate them very easily. The only tool needed is a trusted
thermometer. First answer "Yes" to the "Calibrate Sensors" prompt, then
press the Select Features up button. The controller will then ask for
"Sensor #1 New Temperature" select the proper temperature using the
Change Setting arrow keys. Repeat for each of the four sensors as
needed.
Run Adjustment
The unit automatically runs a certain amount of time for each temperature
difference. If you feel this amount is too much or too little, you may change the
standard amount with this setting. The setting is given as a percent of standard
runtime. Any setting higher than 100 percent will make the machine run
longer, and any setting below 100 percent makes the machine run for a shorter
amount of time.
Initial Drop
Initial drop is the setting that sets the minimum the machine will open. For
example: If you know that it is not safe for the curtains to be less than four
inches open, the initial drop should be set higher than four inches.
Degrees Above Target Before Machine Operates
This feature is used to control exactly when the system switches
from power ventilation to natural ventilation. Many times it is better to
lower a slightly warm inside temperature back into range with side-wall
fans. Degrees above target before machine operates will accomplish this.
When 1 or 2 fans can no longer maintain the proper target temperature,
then the curtains will open and those fans will shut off. We recommend
a 4 to 5 degree setting for this feature.
Ratio
Ratio tells the controller about your house setup. The ratio is a
numerical representation of your curtain machine's pulley arrangement.
The first number represents one inch of movement of the curtain
machine load block. The second number represents the number of
inches the curtain moves for one inch of machine movement. (i.e. 1:2
