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 refrig-
eration system uses the Carel controller on all three
temperature designated models. The models dier 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 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 surface of the front panel (phase 2).
■ Repeat the same operation for the top screw (phase 2).
■ Apply the front frame (phase 3).
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.
* Do not over-tighten the screws.
