Liquid Crystal Display (LCD)
The LCD display provides a constant readout of the sensor temperature and indicates if the output relay is energized. When the S1
annunciator is constantly illuminated during operation, the relay is energized. The display is also used in conjunction with the keypad to allow
the user to adjust the setpoint temperature, differential and heating /cooling modes.
Programming Steps and Display
The control can be programmed in four simple steps using the LCD display and the three keys on the face of the control. (See photo for
display and keys.)
NOTE: Stage 1 must be set for heat mode and Stage 2 for cool mode for correct operation.
1.
To start programming, press the SET key once to access the Fahrenheit/Celsius mode. The display will show the current status, either F
for degrees Fahrenheit or C for degrees Celsius. Then press either the up
designation.
2.
Press the SET key again to access the chill mode setpoint temperature. The LCD will display the current setpoint temperature and the
S1 annunciator will be blinking to indicate that the control is in the setpoint mode. Press either the up
decrease the setpoint to the desired temperature.
3.
Press the SET key again to access the heat mode differential temperature. The LCD will display the current differential and the DIF 1
annunciator will be blinking to indicate that the control is in the differential mode. Then press either up
key to decrease the differential to the desired setting (minimum 1
4.
Press the SET key again to select chill mode. The LCD will display the current mode: H1. Then press either up
down
key to select the correct Stage 1 mode. Stage 1 MUST be in the H1 mode for correct operation.
5.
Press the SET key again to access the heat mode setpoint temperature. The LCD will display the current heat setpoint temperature and
the S2 annuciator will be blinking to indicate that the control is in the setpoint mode. Then press either the up
key to decrease the setpoint to the desired temperature. S1 and S2 should both be set for the same temperature.
6.
Press the SET key again to access the chill mode differential temperature. The LCD will display the current differential and the DIF 2
annunciator will be blinking to indicate that the control is in the differential mode. Then press either up
key to decrease the differential to the desired setting (minimum 1°F, maximum 30
value for best results.
7.
Press the SET key again to access the heating mode. The LCD will display the current mode: C2 or H2 . Stage 2 MUST be in the C2
mode for correct operation.
8.
Press the SET key again to exit programming mode. Controller will display current water temperature.
Controller will automatically drop out of "program mode" and return to "operating mode" 30 seconds af ter last key press.
Troubleshooting Controller Error Messages:
Display Messages
E1 - Appears when the up
To correct: If the E1 message appears even when no keys are being pressed, replace the control.
E2 - Appears if the control settings are not properly stored in memory.
To correct: Check all settings and correct if necessary.
EP - Appears when the probe and or flow switch is open , shorted or sensing a temperature that is out of range.
To correct: Check to see if the sensed temperature is out of range. If not , check for probe damage by comparing it to a known ambient
temperature between -30
is correct, flow switch.
EE - Appears if the EEPROM data has been corrupted.
To correct: This condition cannot be field repaired. Replace the control.
CL - Appears if calibration mode has been entered.
To correct: Remove power to the control for least five seconds. Reapply power. If the CL message still appears, replace the control.
