=====Mechanical assembly=====
The controller CW01R66 consists of two circuit boards - a control board with a display located on the face panel and the [[#relay_board|relay board]] for connecting the control signals.

To secure the controller to the face panel, there must be cut a rectangular opening for the screen and four mounting holes for the bolts and the studs. 
We recommend the installation of a plexiglass cap that protects the controller from mechanical stress and moisture.
