Operation
There are three modes of operation: operation, regulation and initial setting. When power is applied, controller gets into the operation
mode. Press the
key to switch to regulation mode. If the key is pressed for more than 3 seconds, controller will switch to the
initial setting mode. Pressing the
key while in the regulation mode or initial setting mode, forces the controller to return to the
operation mode..
PV/SV: Sets the temperature set point and displays the temperature process value. Use
keys to set the temperature set
point.
Setting method: While in any function mode, press the
key to select the desired function and use keys to change
settings. Press
key to save the changes.
The flow chart below shows how to switch the settings and internal functions:
