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

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.
