IMPORTANT NOTICE-
If a malfunction of an E2 series controller could cause personal injury or damage to equipment or property, other limit or safety controls, or alarm or
supervisory systems, intended to warn and or protect against such occurrences must be incorporated into and maintained as part of the control system.
This redundant built-in safety is required.

DATA-PORT
This PORT transmits data ONLY, it is NOT bi-directional. The frequency at which the data transmissions occur is selected by the data refresh jumper labeled “2S 6M”
on the circuit board (see drawing). Set jumper position to 2S for one complete line of “total system information” to be sent to the computer every 2 seconds, or set to
6M for 6 minutes. Complete instructions are supplied with accessories required to connect to a computer.
DO NOT CONNECT THIS PORT DIRECTLY TO ANY ETHERNET DEVICE OR COMPUTER PORT!

FREEZE PROTECTION OVERRIDE “FZ”-
This feature is available to prevent a “non-drain back” water 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 40 F.
The PUMP relay will then be turned ON until the COLLECTOR temperature
reaches 55 F. Normal control operation will resume above this temperature. To
enable this feature, a jumper must be placed onto the pins marked “FZ” on the
circuit board. Only 1 override can be enabled.

OR
LOW TEMPERATURE SHUT-DOWN OVERRIDE -
This feature is available to prevent a “drain back” 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 pins marked “LO” on the circuit board. Only 1
override can be enabled.

CONTROLLER OPERATION
TEMPERATURE DIFFERENCE CONTROL-
When the temperature difference between the sensor on the solar collector and the sensor in the storage tank(POOL) exceeds the dialed temperature setting on “ON DIF”,
the PUMP relay will actuate after a 30 second delay. The BLUE LED “RLY” indicator will also turn ON. When the storage tank(POOL) temperature falls 4 degrees below the
dialed setting on “ON DIF”, the PUMP relay and the BLUE LED indicator will turn off without delay. See “High Limit Control” below.
HIGH LIMIT CONTROL-
When the temperature in the storage tank(POOL) exceeds the dialed setting on “HI LIM”, the PUMP relay will turn OFF without delay regardless of the temperature
difference that exists between the STORAGE tank (POOL) and the solar COLLECTOR. The BLUE LED indicator will turn OFF and the AMBER LED “ULT” indicator will turn
ON. When the storage tank temperature(POOL) falls 4 degrees below the dialed setting on “HI LIM”, the controller will 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.
POWER & FAULT INDICATORS “LEDs”-
The GREEN LED “PWR” indicator is ON when the microprocessor is POWERED and the SOLAR controller is operating. The RED LED “FLT” indicator will be FLASHING
when there is a FAULT condition. Faults occur when either storage or collector sensor is OPEN or missing, or if any sensor has resistance OUT of RANGE, or when the
pump RELAY SWITCH is NOT set to “AUT” (automatic) position. It is also possible that an internal circuit malfunction initiates the FAULT condition.
