Set system parameters
Keep〖P〗depressed for 3 seconds to enter into parameter setting status:
blinks, dispay shows “U10”, the 1
st
system parameter code.
Press〖▲〗or〖▼〗to select parameter code.
Press〖S〗to show the value of the parameter.
Press〖▲〗or〖▼〗to the value of the parameter.
Press〖S〗to return back to parameter code selection.
In this way, we can check and/or set all parameters.
Keep〖P〗depressed for 3 seconds to save and exit the status.
The status will exit, and the value will be saved, when there is no key operation for 30 seconds.
If parameter U99 value is not “0000”, the password (the value of U99) is required to enter into parameter setting status:
After〖P〗depressed for 3 seconds, display shows “---0”.
Press〖▼〗to select the digit of password, press〖▲〗to set the value of the digit.
After 4 digits are set, press〖S〗to enter the password.
If the password is correct, enter into the parameter setting status. Else exit.

Control
Timer output R2
During timer on period (U41, U40), the R2 will be energized.
During timer off period (U43, U42), the R2 will be de-energized.
Temperature control
PID control (U74 = 0)
PID control. The output for heater is R1.
Hysteresis control (U74 = 1)
When measured ≥ Set-point (SP), R1 de-energized. When ≤ Set-point (SP) – U14, R1 100% energized.
