An IMC LCD MASTER DIGITAL DISPLAY PANEL can also be connected to the DATA PORT. It has an RJ-45
jack and is supplied with a 3 foot long cable that can be substituted with a standard CAT5 cable up to150 feet long.
These ethernet cables are available at most retail stores. The display panel also has a PEAK RESET button
located on the side to reset previous STORAGE temperature peaks.
The Information on the LCD MASTER DISPLAY PANEL is displayed as follows:
COLLECTOR TEMPERATURE
STORAGE TEMPERATURE
DIFFERENTIAL CONTROL SETTING
HI LIMIT CONTROL SETTING
PUMP STATUS
UPPER LIMIT STATUS
PEAK HI= MAXIMUM TEMPERATURE
PEAK LO= MINIMUM TEMPERATURE
AUXILIARY SENSORS 1 AND 2
This Master LCD has a second page that will
display the auxiliary sensor temperatures.
To display, press and release the PAGE/RESET
button on the side of the display housing.
The auxiliary sensors will be displayed within 2
seconds. To RESET the STORED PEAK
temperatures of the storage tank, press and hold
for 6 seconds the PAGE/RESET button. The
current temperatures will appear after the button
is released. The Master LCD display is updated
every 2 seconds.
DATA-PORT
Requires an IMC Data-Port ADAPTER that will allow interface to a standard computer’s serial RS232 port. The
ADAPTER can also accept a serial to USB converter to connect directly to portable computers 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 on page 4. If the jumper is placed on position labeled “2S”,
one complete line of “total system information” will be sent to the computer every 2 seconds which is necessary
when performing diagnostics or a system startup. If the same jumper is placed on 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 setup in the computer’s communications program such as
“Terminal” or “Hyper Terminal”.

CONTROLLER OPERATION
TEMPERATURE DIFFERENCE CONTROL- When the temperature difference between the sensor on the
solar collector and the sensor in the storage tank exceeds the dialed temperature difference setting (ON DIF),
the PUMP relay will actuate after a 30 second delay. The BLUE LED indicator will also turn ON. When the
temperature difference decreases and falls below 4 F (2.2 C), the PUMP relay and the BLUE LED indicator will
turn off without delay.
HIGH LIMIT CONTROL- When 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 OFF. When
the storage tank temperature falls 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 switching ON 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 F. The PUMP relay will then be turned OFF. Normal control
operation will not resume until the COLLECTOR temperature returns to 70 F or above. To enable this feature,
a jumper must be placed onto the jumper pins marked “LO’ on the circuit board. Only ONE of these two
override features can be enabled.
FREEZE PROTECTION OVERRIDE- This feature is available to prevent a non-drain back “water only” system
from freezing when the outdoor temperature drops too low. If this feature is enabled normal operation will stop
when the COLLECTOR temperature falls below 37 F. The PUMP relay will then be turned ON until the
COLLECTOR temperature reaches 52 F. 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.
STATUS INDICATION LEDS- There are four status indication LEDS. The GREEN LED indicates that the
microprocessor is POWERED and the SOLAR controller is running. The BLUE LED indicates PUMP operation.
When ON, the PUMP is operating and solar energy is being stored in the STORAGE tank. The AMBER LED
indicates if the UPPER LIMIT temperature in the storage has been exceeded. The RED LED indicates when
there is a fault condition. The conditions that can cause the fault LED to turn ON are as follows: OPEN or
SHORTED or OUT of RANGE temperature SENSORS, pump RELAY SWITCH NOT set to “AUT” (automatic)
position and internal component malfunctions. The RED LED will always be FLASHING when the FAULT
indication is ON
SENSORS- Industrial 400°F (204°C) rated 10K IMC thermistors have +/- 1°F accuracy. When installed, they
will not exceed ONE degree of additional error for cable distances up to 1000 feet of 18ga., 700 feet of 20ga. or
500 feet of 22ga.
SENSOR SCREW TERMINALS- There are 9 screws on a GREEN block located at the top edge of the board.
These terminals accept solid or stranded wire from 18ga. to 22ga. They are NEC class 2 circuit connections.
POWER AND RELAY TERMINALS- The power terminals are for 120 vac operation (230 vac operation is
optional). Use solid wire in 16 or 18 ga. and stranded (19 max) in 12 or 14 ga. The power RELAY is rated for 20
Amps and is designed to connect directly to PUMPS or FANS not exceeding a total of 1 hp. A 30 amp.
(resistive load) board option is available. Current and voltage ratings will vary for models with cords and
receptacles. See model label for specific ratings.

INSTALLATION
MOUNTING- The Eagle line of SOLAR controllers are designed to be mounted indoors, protected from rain and
condensing moisture. Use two #10 screws in the enclosure “keyholes” for mounting.
POWER WIRING- Hard wired models are designed for 120 vac operation unless special ordered. If relay is
wired to switch any voltage other than 120 vac then the “20 AMP RELAY JUMPER” MUST BE REMOVED. Use
solid wire in 16 or 18 ga. and stranded (19 max) in 12 or 14 ga. Same gage and stranding must be used under
both sides of each clamping washer. All wiring must be done in accordance with local codes. Models supplied
with line cords and receptacles are to be connected directly to power outlets without the use of extension cords.
Line and power wires should NOT be bundled with or placed in the same conduit with sensor or data cables.
SENSOR INSTALLATION AND WIRING- Sensor installation should be in a manner as to permit proper sensor
contact of the areas to be measured. Shield and/or insulate the sensors to prevent them from being affected by
the surrounding ambient temperatures. Sensor wiring installed outdoors must be rated for OUTDOOR use.
It is recommended in today’s Radio interference “RICH” environment that all sensor wiring be shielded.
The cable SHIELDS must be brought to the shield grounding terminal that is the rightmost position on the
GREEN terminal block. See controller layout diagram. For ease of shield installation, insert one short wire in
the shield terminal labeled “SHLD” and connect all the shields together with a “wire-nut”or other reliable means.
Ungrounded shields may result in damage to the Solar controller circuits. The shield requires grounding at the
controller side ONLY. DO NOT attempt to ground the collector panel with the sensor shield.
For efficient and reliable wire connections, strip 3/8” (slightly shorter than block width) of insulation from an
undamaged wire end. Use a strip tool that will not nick the conductors. If wire is solid, make sure that the tip is
NOT pinched or deformed so that it will fit into the terminal hole easily. If the wire is stranded, make sure the
strands are tightly twisted. Using a elect the appropriate screw and turn
CCW to open the terminal hole fully. Then guide the wire into the terminal hole and hold while tightening (turn
CW) the screw to clamp the wire.
slip off the
screw and damage any circuit components. If the wire is stranded, make sure that ALL the strands are properly
clamped in the terminal.
COLLECTOR GROUNDING- The Solar collector panel array “must be GROUNDED’ directly to an earth
ground line. This is necessary to prevent damage from nearby lightening strikes which induce very
DAMAGING high voltages in all nearby ungrounded metallic surfaces. Please consult local, state and federal
codes for proper grounding.
DATA LOGGING TO ACOMPUTER- All the EAGLE Solar controllers can be connected to the serial port of a
PC or Laptop computers. An IMC DATA PORT/RS232 adapter is required. The maximum recommended
adapter cable length is 500 feet. All Windows operating systems have a communications programs such as
“Terminal” or “Hyper Terminal” which are used to receive and/or CAPTURE data from the PC’s serial port.
This feature is “EXTREMELY” valuable in starting up newly installed SOLAR systems. Long-term data
logging is now possible which can be very useful in service and diagnostics of intermittent malfunctions.
Complete “system status” including temperature is presented in a line by line format including timer
information. In applications were the computer’s interface is going to be permanent it is recommended that
the EAGLE WEB model be used in order to protect the connecting computer from electrical surges.
Please visit our website for news or more detailed instruction at “www.solar.imcinstruments.com”.
All
connections exposed to the weather must be made with waterproof “outdoor” rated connectors.
Listed
below are a few suggested wire part numbers. Wire selected must also meet local codes and be rated for
indoor/outdoor use by its manufacturer.
1) “PLTC” Belden # 9322 (22ga) or 9320 (20ga) Best specifications
2) “Control” Belden # 8761 (22ga) or 8762 (20ga) Better specifications
3) “Audio” Belden # 9451-10 Black (22ga) Acceptable specifications
