STC-1000X Microcomputer Temperature Controller User Manual

Overview

STC-1000X temperature controller features cooling and heating modes with automatic 
switch, temperature unit switch between Celsius and Fahrenheit, temperature control 
by set-point and differential, temperature calibration, cooling output protection delay, 
sensor fault alarm and other functions. The controller reserves an interface of RS-485 
communication function for further connection to an Elitech IoT module which makes 
remote control available.

Button Instructions

Quick Start

1. Unlock the keyboard

Under normal operating status, the buttons will be locked after 10 seconds of 
inactivity, and the button lock indicator       will be on. Hold             button for more 
than 3 seconds to unlock the buttons and       will be off.

2. View parameters 

Under normal operating status, press and release 

 button to display the temperature 

set-point; press and release 

 button to display the temperature differential set-point. 

The controller will be back to normal display status after 2 seconds.

3. Set parameters 

Under normal operating status, press and hold          button for more than 3 seconds 
to enter parameter setting mode. The             indicator will be on and the first code F1

Press and release: Back to previous menu

Hold for 3 seconds: Turn ON/OFF; 

.

 

Press and release: Display temperature set-point and back to normal display after 2 seconds. 

 

Press and release: Display temperature differential set-point and back to normal display after 2 
seconds. 

 

 

Hold for 3 seconds: Unlock the keyboard or enter parameter setting mode

will be displayed in the panel. Press 

 or 

 button to scroll up or down menu items 

and display the corresponding code. Press        button to display the current parameter 
set-point. Press 

 or 

  button again to increase or decrease the value and press                

to back to parameter code display. 
If you need to save the settings, please press and release        button and back to normal 
display status. If not, just keep the controller inactive for 10 seconds, it will be back to 
temperature display status. If an error occurs during saving settings, the panel will 
display

 Er

 and back to temperature display status in 3 seconds.

4. Operations 

Under normal operating status, the panel displays currently measured temperature 
and automatically recognizes and switches cooling and heating modes.
- If measured temperature   temperature set-point + temperature differential, and 
compressor delay time   F3, the controller starts cooling mode and        indicator is on.
- If measured temperature   temperature set-point, the controller stops cooling and     
         indicator is off.
- If measured temperature   temperature set-point - temperature differential, the 
   controller starts heating mode and       indicator is on.
- If measured temperature   temperature set-point, the controller stops heating and 
          indicator is off.

5. ON/OFF

Hold the power button      for more than 3 seconds to turn on/off the controller.

Fault 

Alarm

When the temperature sensor is short circuit or open circuit, the controller will start 
fault alarm mode and turn off all the outputs, the buzzer will beep and the panel will 
display 

EE

. Press any button to mute the buzzer. 

The controller will return to normal operating mode after the fault is removed.

Safety Precautions

Important!
1. Distinguish the sensor lead, power cord and output relay interface. Do not connect 
wrong or overload the relay.
2. Cut off power supply before wiring.

Warning!

Do not use the controller in water or too humid environment, or environments at high 
temperature, with strong electromagnetic interference or strong corrosion.

Wiring Diagram

Caution!

1.  The power voltage must be in accordance with the voltage labeled on the controller. 
     Please ensure the stability of power voltage.
2. Separate as much as possible the sensor lead from power cables to avoid possible 
     electromagnetic disturbance.
