Elitech STC-1000X 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.

If you need to save the settings, please press and release
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
- 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
- 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.

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.
