 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 the
settings. Press key to save the changes.
 The flow chart below shows how to switch the settings and internal functions:
