System 1000™ Power Curtain™ Controller 7
To View Records, push the Select Feature up arrow key until View Records is displayed.
Use the Change Setting up arrow key to select yes. Use the Select Feature up arrow key
after selecting yes to see the display Sensor 1, number of hours, amount of low and
amount of high. To view the remaining sensors, use the Select Feature up arrow key.
After the sensors have all been displayed, the Select Feature will display Sensor 1
Average - or + from target and the total amount of hours it has been recording. To view
the remaining sensors, use the Select Feature up arrow key. After the sensors have all
been displayed again, the Select Feature will display Stage 1 Runtime. To view the
remaining stages, use the Select Feature up arrow key. Push Select Feature again. It will
display Reset Records. Use the Change Setting up arrow key to choose whether you wish
to clear the records and start over (yes) or (no).
Example of Sensor 1 Display:
Sensor 1 14.37 hours
Low 4.0 degrees F. High 1.0 degrees F.
This means that Sensor 1 has been keeping records for 14.37 hours and during that
time, the temperature at Sensor 1 has dropped to a low of 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.
Example of Stage 1 Display:
Stage 4 Runtime
10 hours and 2 min.
This means that Stage 4 has operated for 10 hours and 2 minutes since records were last
reset. The time may be seen in one of the sensors' displays and in this case would be
14.37 hours.
7.10. 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.
7.11. 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.
7.12. 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 ratio--one inch
of machine movement gives two inches of curtain movement.) Although there are many
