Key Instruction
Key Operation Instruction
- Check parameter: In normal working status, the screen displays real-time temperature.
- Press
. It displays the setting temperature value.press™
. It displays the difference value. Press
to back to the normal display. - Set parameter: In normal working status, press S for 3s to enter set parameter mode.
- Press to switch from F1-F4.(see menu code table).
- Press S to display the parameter set value of the current code. Press and hold S, Press again to adjust the parameter setting value of the current code.
- Press and hold both S and A simultaneously to choose and adjust the parameter value of the current menu value promptly.
- After finishing the setting, press, and release instantly save the parameter modified value and return to the normal display.
- If no key operation within 30 seconds, the system won’t save the modified parameter, and screen back to display the normal temperature.
- The screen displays “Er” if the error appears during parameter saving, and back to normal working status in 3 seconds.
Restore system data: When electrified, the system will check itself, and the screen will display”Er” If the error exits, please press any key at this time, and it restores the default value and enters into normal working mode. It is advised to reset the parameter
value under this condition.
Operation Instruction
In normal working status, hold for seconds to power off, and hold for 3 seconds to power on. In normal working status, the screen displays RT(real-time temperature value). The controller can also switch the working mode between heating and cooling. Refrigerating starts when RT ≥ST (temperature set value) + F2 (difference value), and the refrigerating relay is connected.
- The cool indicator flashes. It indicates the refrigerating equipment is under compressor delay protect status; When RT ST, the cool indicator light is off, and the refrigerating relay disconnects. The cooler stopped working.
- Heating starts when RT ≤ ST-F2, heat indicator light on. Heat relay connects. When RT≥ST, the heat indicator turns off, the heat relay disconnects, heater stops working.
For example,set 10 °C ,difference 3 °C heater work:
- RT <7°C heater stops when RT ≥ 10°C. Cooler work when
- RT ≥ 13°C, Cooler stops when RT ≤ 10°C.
