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.
