Thank you for purchasing HM Digital’s CIC-152. The CIC-152 is a TDS/EC controller that monitors and controls levels
of Total Dissolved Solids (TDS) or Electrical Conductivity (EC) in water. The controller has two programmable control
points (maximum limit (CP2) and minimum level (CP1)) to help maintain the TDS/EC within a designated range. If
the TDS/EC level is within the range, the controller will display a green light. Each control point can be used to
control a distinct device, or both can be used to control a single device. If the TDS/EC level descends to Control
Point 1 (CP1), the controller will activate a yellow warning light, and switch the dry contact position of Relay 1 from
the normal position (to operate a valve, pump, etc). Once the TDS/EC ascends over CP1, the light will revert to green
and switch the contacts of Relay 1 back to the normal position (normally open or closed). If the TDS/EC level rises to
Control Point 2 (CP2), the controller will activate a red warning light, and switch the dry contact position of Relay 2
from the normal position (to operate a valve, pump, etc). Once the TDS/EC level drops below CP2, the light will
revert to green and switch the contacts of Relay 2 back to the normal position (normally open or closed).

ATTACHING THE MOUNTING BRACKETS
1. Slide the controller through the hole in the panel.
2. From the rear of the controller, slide the metal square support frame over the controller, so that it is
pressed against the interior of the panel.
3. If not assembled, on the top of the controller, place one long bracket with the ridge side facing up.
Insert the short bracket into the slots on the controller, so that it ts snugly against the long bracket.
4. Slide the long bracket towards the controller face, so that the front end is pressed against the support
frame (or the panel, if not using the support frame).
5. Secure a screw from the hole in the long bracket through the hole in the short bracket. Tighten, but
do not overtighten.
6. Do the same for the bracket on the bottom of the controller. Tighten both brackets equally.

INSTALLATION INSTRUCTIONS
USAGE INSTRUCTIONS
1. Remove the contents from the box.
2. Insert the controller into the panel. A square hole must be cut into the panel with dimensions
of 2-5/8 in. x 2-5/8 in. (66.5 mm x 66.5 mm). Page 8 includes a cut-out diagram.
3. Mount the controller to the panel according to the directions on page 7.
4. View the contact diagram on the side of the controller on page 8.
5. Do NOT connect to a power source yet! Connect the black power cord to the contacts #8 & #10 (110 V) or
#8 & #9 (220V). It does not matter which color wire is connected to the contacts. Screw in tight with a
Phillips head screwdriver. (Note – If in the U.S. (or a country that uses Type A or B plugs/sockets), connect
the included plug adapter to the plug).
6. Connect a device (valve, pump, etc.) to be controlled by the upper limit (CP2) with a relay cord (not
included) to contacts #13 and #14 for a normally open position OR to contacts #12 and #13 for a normally
closed position.
7. Connect a device (pump, valve, etc.) to be controlled by the lower level (CP1) with a relay cord (not
included) to contacts #6 and #7 for a normally open position OR to contacts #5 and #6 for normally closed.
8. OPTION: Both control points (CP1 and CP2) can operate the same device. To do this, double up on the
contacts of the device and connect a set of wires to each set of contacts on the CIC-152.
9. Connect the gray sensor cable by attaching the blue wire to contact #1, the red to #2, the white to #3 and
the black to #4.
10. Align the pins of the sensor to the cable and attach. Screw the tightening ring closed.
11. Insert the sensor electrode into a female ½”NPTF threaded tting. The sensor can be in still or owing
water. If using with owing water, ensure the sensor pins are orientated so that the ow of water is
perpendicular to the pair of pins. (If looking through a T-tting with the sensor in the T, you should be
able to see both pins side-by-side.) Attach to your water source.
12. Plug the power cord into an electrical outlet. The controller does not have a power switch and will
automatically power on when the power is connected.

Sensor Replacement
TROUBLESHOOTING
The controller will not power on.
Incorrect readings.
The relay controls do not work.
The display shows ERR.
1. Check to ensure the connections are correct (double-check
110V vs. 220V).
2. Check to ensure the power cable is plugged in.
1. Try to recalibrate the controller. Note that the calibration
should be done with a tting on (if using a tting).
2. Note the instructions for upper level calibration.
3. Check for interference caused by other machinery or
electronics (near the controller, cables or sensor).
1. Double-check the connections for the relays.
2. Make sure that the set point is properly set for CP1 and CP2.
1. The TDS/EC level is out of range.
2. The sensor is not connected.
3. The sensor is dirty or damaged.
Problem Potential Solution(s)
If troubleshooting does not solve the problem, please contact HM Digital for assistance. If you feel that the
controller is defective, please refer to the warranty (page 6) and return it for repair or replacement.
Setting the Control Points and Alarm Points
Lower Level Control Point 1 (CP1)
1. To set the control points (to activate a device via the relay), press the SET button once. The
temperature reading will switch to a ashing “CP1”and the measurement will switch to the
current control point. CP1 will switch the contacts #5, 6, 7 from the normal position when the
TDS level drops to the CP1 setting or below.
2. Press the UP or DOWN buttons until the desired minimum TDS level set point is reached. Pressing once
will advance the reading by a single digit. Holding down the button will advance the reading quickly.
3. Press the SET button again. This will save CP1 to memory and advance to CP2.
Upper Limit Control Point 2 (CP2)
4. After CP1 is set,“CP2”will ash and the current control point will be displayed.
5. Press the UP or DOWN buttons until the desired maximum TDS level set point is reached. Note that CP2
cannot be below CP1 and vice-versa.
6. Press the SET button again. This will save CP2 to memory and advance to AL1.
Lower Alarm 1 (AL1)
7. After CP2 is set,“AL1” will ash and the current lower alarm will be displayed.
8. Press the UP or DOWN buttons until the desired lower alarm set point is reached. To DEACTIVATE the
alarm, press the ALARM ON/OFF button. “OFF” will ash on the display.
9. Press the SET button again. This will save AL1 to memory and advance to AL2.
Upper Alarm 2 (AL2)
10. After AL1 is set,“AL2” will ash and the current upper alarm will be displayed.
11. Adjust AL2 with the arrow buttons. To DEACTIVATE the alarm, press the ALARM ON/OFF button.
12. Press the SET button again. This will save AL2 to memory and revert to measurement mode.
To clean the sensor electrodes, use rubbing alcohol and a cotton swab. Lightly clean the electrodes. Rinse
with DI, RO or distilled water. Air dry. Never touch the electrode pins, as skin oils will aect the reading.
Cleaning
Calibration
1. HM Digital factory calibrates the controller to a 1413 µS KCl solution (700 ppm NaCl). If you wish to
recalibrate, press and hold the CAL button. The temperature reading will switch to a ashing“CAL.”
2. Insert the sensor (with the tting on) into a calibration solution with a known value.
3. Press the UP or DOWN buttons to adjust the reading until it matches the value of the calibration solution.
4. Once the display matches the calibration solution, press and hold the CAL button again to set it.
HIGH RANGE CALIBRATION: In high ranges, the calibration display will advance or decrease by approxi-
mately 1% of the reading with each push of the UP or DOWN button. For ne tuning, adjust the display
as close as possible to the desired level. Then, with a small screwdriver, adjust the trimmer pot on the top
of the controller clockwise or counter-clockwise. This will allow for pinpoint calibration.

HELPFUL TIP:
When the TDS is over CP1, R1 is in the normal position.
When the TDS is below CP2, R2 is in the normal position.
Example of use: The TDS (wavy line) starts above CP2, descends below CP2, below CP1 and back up (and down).

Using the Alarms
When the TDS/EC level is at or below AL1, the alarm will sound.
When the TDS/EC level is at or above AL2, the alarm will sound.
The alarms are independent of the control points.
To turn o an alarm, this most be done in set mode (see below).
