Elitech STC-1000X Temperature Controller User Manual
Overview
Elitech 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.

Operation & Diaplay Panel
Button Instruction
| ON/OFF Button | Hold for 3 seconds: Turn ON/OFF; Press and release: Back to previous menu. |
| Up Button | Press and release: Display temperature set-point andback to normal display after 2 seconds. |
| Down Button | Press and release: Display temperaturedifferential set-point and back to normal display after 2 seconds. |
| Set Button | Hold for 3 seconds: Unlock the keyboard or enter parameter setting mod.e |
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 lock indicator 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 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 cooling indicator is on.
- If measured temperature temperature set-point, the controller stops cooling and cooling indicator is off.
- If measured temperature temperature set-point - temperature differential, the controller starts heating mode and heating indicator is on.
- If measured temperature temperature set-point, the controller stops heating and cooling indicator is off.
5. ON/OFF
Hold the power button for more than 3 seconds to turn on/off the controller.

| F3 | Compressor Start Delay | 0~10 min | 3 | |
| F4 | Temperature Calibration | -10℃~10°C/-10~10℉ | 0℃/0℉ | |
| F5 | Temperature Unit | 0: ℃; 1: ℉ | 0 | |
| F6 | Communication Address | 1~127 | 1 | Reserved |
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 willdisplay 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.
