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 the keys to change settings.
Press
key to save the changes.
