Core Control Parameters
When configuring or troubleshooting a Lae Electronic system, technicians primarily adjust these key parameter settings:
Parameter
Function Description
SP
Set Point: The targeted internal temperature for the system.
SPL / SPH
Set Point Limits: Defines the absolute minimum and maximum temperatures a user is allowed to select.
1HY
Hysteresis: The temperature differential that determines when the compressor cycles back on.
CRT
Compressor Rest Time: The minimum off-time in minutes to prevent short-cycling damage.
DFT
Defrost Time Interval: The cyclic time elapsed between structural defrost cycles.
Basic Programming Instructions
Enter Menu: Press and hold the two outermost buttons simultaneously for five seconds until the parameter code appears.
Navigate: Use the up or down arrow buttons to cycle through the codes (e.g., SP, SPL, DFT).
View / Edit: Press and hold the "i" (info/set point) button to display the value, then use the arrows to adjust it.
Save & Exit: Release all buttons. The settings save automatically, or you can tap the standby/exit button to return to the normal display.
