OPERATION- LCD DISPLAY

The LCD display has 2 lines of 20 characters each. The first line permanently displays the COLLECTOR and
the STORAGE temperatures. The second line can be paged by pressing the button located just below the
LCD display. The following 4 pages display all system information including OVERRIDE messages.

relay will actuate after a 30 second delay. The BLUE LED indicator will also turn on. If the temperature difference
decreases and falls below 4 F (2.2 C), the PUMP relay and the BLUE LED indicator will turn off with out delay.

HIGH LIMIT CONTROL

- If the temperature in the storage tank exceeds the HI-LIMIT dialed setting, the PUMP
relay will be turned OFF without delay regardless of the status of the “temperature difference” that exists between
the STORAGE tank and the solar COLLECTOR. The BLUE LED indicator will also turn be turned OFF. Should the
storage tank temperature fall 4 degrees below the setting in the HI-LIMT, the controller will then resume normal
operation. The PUMP relay will always have a 30 second delay before actuation into the ON position and the BLUE
LED will always show its STATUS condition.

LOW TEMPERATURE SHUT DOWN OVERRIDE-

This feature is available to prevent the system from operating at
low outdoor temperatures. If this feature is enabled normal operation will stop when the COLLECTOR temperature
falls below 50 degrees F. The
the COLLECTOR temperature returns to 70 degrees or above. To enable this feature,

If this feature is enabled normal operation will stop when the
COLLECTOR temperature falls below 37 degrees F. The PUMP relay will then be turned on until the COLLECTOR
temperature reaches 52 degrees. Normal control operation will resume above this temperature. To enable this
feature, a jumper must be placed onto the jumper pins marked “FZ’ on the circuit board. Only ONE of these two
override features can be enabled.

DATA PORT-

Requires an IMC-Data port/RS232 ADAPTER. This will allow interface to a standard PC serial port.
The ADAPTER can further accept a serial/USB converter to connect directly to PC or Laptops that only have USB
ports. If wireless operation is desired for short distances, BLUE TOOTH transceiver can also be connected. The
rate at which the data is sent from the EAGLE solar controller is determined by a jumper in the controller as show in
the CONTROLLER diagram. If the jumper is placed in position labeled “2S”, one complete line of “Total system
information” to the PC every 2 seconds which is necessary when performing diagnostics or a system startup. If the
same jumper is placed in position labeled ”6M’, then DATA will be sent every 6 minutes. This will allow a more
suitable data-send rate for long term DATA LOGGING, specially when storing the data in a “CAPTURE” file set up in
the PC “Terminal” communications program such as “Hyper Terminal” or “Terminal”.
