Single or Dual Stage Temperature Controllers

Ranco ETC


DESCRIPTION:

The Ranco ETC is a microprocessor based electronic temperature controller designed to provide on/off control of heating and cooling (Chillers) . The ETC is equiped with a Liquid Crystal Display(LCD) that provides a constant readout of the sensed temperature, and a touch keypad that allows the user to easily and accurately select the set point temperature, differential set point, and heating or cooling mode of operation. The unit can be operated on either line voltage, 120/208/240VAC. With its wide temperature setpoint range and selectable heating or cooling modes, the ETC can be used for a wide variety of applications such as Research, Science, Laboratory, Education, Aquariums, Hydroponics, Pools and more..

Some of ETC's outstanding features include:

 Step 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 up or down arrow key to toggle between the F or C Designation.

  Fahrenheit or Celsius Scale

 

 Step 2

  Press SET key again to access the setpoint. The LCD will display the current setpoint and S1 annunciator will be blinking on and off to indicate that the controls in the setpoint mode. Then press either the up key to increase or the down key to decrease the set point to the desired setting.

  Setpoint Temperature

 

 Step 3

  Press SET key again to access the differential. The LCD will display the current differential and DIF1 annunciator will be blinking on and off to indicate that the controls in the differential mode. Then press either the up key to increase or the down key to decrease the differential to the desired setting.

 Step 4

  Press SET key again to access the cooling or heating mode. The LCD will display the current mode, either C1 for cooling H1 for heating. Then press either the up key or the down key to toggle between the C1 or H1 designation. Press the SET key once more and programming is complete.

Troubleshooting error messages

Display

  Messages  To correct

 E1

  Appears when either the up or down key is pressed when not in the programming mode  If the E1 message appears even when no keys are being pressed, replace control.

 E2

  Appears if the control settings are not properly stored in memory.  Check all settings and correct if necessary.

 EP

  Appears when the probe is open, shorted or sensing a temperature that is out of range.  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°F and 220°F. Replace the probe if necessary.

 EE

  Appears if the EPROM dada has been corrupted.  This condition cannot be field repaired. Replace the control.

 CL

  Appears if calibration mode has been entered.  Remove power to the control for at least five seconds. Reapply power. If the CL message still appeared, replace the control.
