PRO3 Top Mount Packaged Refrigeration System Outdoor

Programming the PJEZC Carel

Electronic Controller

Reprinted with permission from Carel.

The Carel PJEZC control is a fully configurable electronic refrigeration controller. The Top Mount packaged refrigeration system uses the Carel controller on all three temperature designated models. The models differ by a pre-programmed parameter list that is specific for each application.

There are two levels of programming with the C controller. The first level can be accessed through the keypad. Set Point (st), Interval between defrost (do), Maximum Defrost Duration (dP), and Dripping Time (dd) are examples of first level parameters. Second level parameters can be accessed by entering a password. See “Modifying Parameters” (page 17).

Installation and Removal

PANEL INSTALLATION FROM THE FRONT USING SCREWS

 

 

 

 

• The thickness of the fastening panel must not exceed 3 mm;

 

 

 

 

• Remove the front frame and make sure that the two catches

 

 

 

 

are in place (these must not protrude from the outline of the

 

 

 

 

drilling template). If necessary, unscrew the two screws. Do not

 

 

 

 

unscrew excessively, the screws must not be detached from the

 

 

 

 

front panel (phase 1);

 

 

 

 

• Insert the instrument in the opening in the panel and hold it in

 

 

 

 

position by the centre of the front panel (phase 1);

 

 

 

 

• Using the screwdriver, tighten the bottom screw 90°, the catch

 

 

 

 

must come out of its slot and click onto the panel, then tighten

 

 

Controllers

 

until the front panel is secure; Do not over-tighten, when the

 

 

 

 

 

 

 

front panel is secured blocks simply make another ½ turn to

 

 

 

 

compress the gasket; If the catch does not click onto the panel,

 

 

 

 

unscrew the screw, applying pressure at the same time with

 

 

 

 

the screwdriver so that the catch moves back. Do not unscrew

 

 

 

 

too much, the head of the screw must not be raised from the

 

 

3.

 

surface of the front panel (phase 2);

 

 

 

 

 

 

 

• Repeat the same operation for the top screw (phase 2);

 

 

 

 

• Apply the front frame (phase 3).

 

 

 

 

 

 

 

 

 

* Do not over-tighten the screws.

DISMANTLING USING THE SCREWS FROM THE FRONT

•Unclip the front frame;

•Unscrew the bottom screw, at the moment the front panel detaches from the panel keep pressure on the screw and unscrew a further 90° to make the catch go back into its slot;

•Repeat for the top screw;

•Remove the instrument from panel, keeping it horizontal
