Recommended Unit Placement For PTT Models
Some general rules for the evaporator section placement which
must be followed are:
1.
Ensure that the structural integrity of the box can
withstand the weight of the top mounted equipment.
2.
3.
The air pattern must cover the entire room.
NOTE: Always avoid placement of
units directly above doors
and door openings.
NEVER locate the evaporator section over doors.
4.
5.
Location of aisles, racks, etc. must be known.
Never remove or unlock any panel cam-locks to install
top mounted equipment.
The size and shape of the storage will generally determine the type
and number of units to be used and their location.

least once for proper defrosting because the amount and pattern
of frosting can vary greatly. The frost build-up is dependent on
the temperature of the room, the type of product being stored,
how often new product is brought into the room and percentage
of time the door to the room is open. It may be necessary to
periodically change the number of defrost cycles or adjust the
duration of defrost.
4. When the fixture temperature rises above the set point
and minimum off-time has elapsed, the temperature
control will close and re-energize the compressor contactor.
System Standard Maintenance Guidelines
After first year of operation and under normal usage, maintenance
should cover the following items at least once every six months:
Electric Defrost Sequence of Operation
for Freezers
1. During normal operation, at the preset time intervals,
the temperature/defrost control will de-energize the
compressor contactor and evaporator fans and energize
the defrost heaters. These functions are controlled
through relays on the controller.
1. Check and tighten ALL electrical connections.
2. Check all wiring and insulators.
3. Check contactors for proper operation and for worn
contact points.
4. Check all fan motors. Tighten motor mount bolts/ nuts
and tighten fan set screws.
5. Clean the condenser coil surface.
6. Check the operation of the control system. Make certain
all safety controls are operating properly.
7. Check that all defrost controls are functioning properly.
8. Clean the evaporator coil surface.
2. When the coil has defrosted fully and has reached the
preset coil temperature (as sensed by the coil
temperature sensor) the defrost heater de-energizes
and the fan delay and drip sequences begin.
3. The temperature/defrost control energizes the
compressor contactor, starting the compressor and
condenser fan(s).
4. Freezer evaporator fans will be energized by the
temperature/defrost control when the coil temperature
reaches 35°F or fan delay time has elapsed.
9. Clean the drain pan and check the drain pan and drain line
for proper drainage.

Refrigeration/Defrost Sequence of Operation
The sequence of operation varies depending on the model that has been installed. The three basic models are Low Temperature, Medium
Temperature, and High Temperature models. The particular model can be determined by the seventh digit of the model number. See Tables
1-3 for details and settings.
Control of the refrigeration and defrost system is provided by the Carel controller along with a space (box) temperature sensor and a coil
(defrost) temperature sensor. The controller will control on and off switching for the compressor, condenser fan motor(s) (cycles with the
compressor), evaporator fan motor(s) and electric defrost heaters for electric defrost.
The Carel controller is pre-programmed for all three applications. This is done with the use of the parameter list. The parameter list can be
changed by entering the Carel Controller and changing the “EZY”setting. See page 15.

PANEL INSTALLATION FROM THE FRONT USING SCREWS
•
•
The thickness of the fastening panel must not exceed 3 mm;
Reprinted with permission from Carel.
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);
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.
•
•
Insert the instrument in the opening in the panel and hold it in
position by the centre of the front panel (phase 1);
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).
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).
* 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

The easy and easy compact devices control the desired temperature
(set point) inside the cabinet or cold room directly and dynamically.
To view and modify the set point:
•
•
•
press SET for 1 s, the set value will start flashing;
increase or decrease the value using UP or DOWN;
press SET to confirm the new value.
The max and min limits of the absolute temperature
parameters are the same for both °C that °F. The range of
temperatures allowed is therefore different between °C
and °F:
MANUAL DEFROST
Press DOWN for more than 3 s (activated only if the temperature
conditions are right).
/6: disable decimal point
Used to enable or disable the temperature display with the
resolution to the tenths of a degree between -20 and + 20 (easy) or
-10 and +10 (easy compact).
CONTINUOUS CYCLE
Press UP+DOWN for more than 3 s (activated only if the temperature
conditions are right).
/6= 0 temperature displayed to the tenth of a degree;
/6=1 temperature displayed without the tenths of a degree.
The continuous cycle is used to maintain refrigeration active in the
cabinet or cold room, regardless of the temperature inside the unit.
This may be useful for rapidly bringing the temperature below the
set point value.
NOTE: the decimal point is only disabled in relation to the reading
shown on the display (the calculations performed by the controller
remain unchanged).
RAPID DISPLAY OF THE TEMPERATURE READ BY THE OTHER
PROBES
Press the DOWN button to scroll the temperatures read by the
probes. Each time the DOWN button is pressed, the display will
show the name of the probe Pr1, Pr2 or Pr3 (only on the models
with 3 inputs and with multifunction input configured as a probe)
and after 1 s the temperature measured by the selected probe will
be displayed.
Temperature Control
The following parameters are used to control the temperature: St,
r1, r2, r3, r4 and rd.
St: set point, r1 minimum value and r2 maximum value of the
set point
Parameter St determines the desired temperature to be maintained
inside the cabinet or cold room (set point). Parameters r1 (minimum
value) and r2 (maximum) set the range of temperatures for setting
the set point.
To display the other probes, press DOWN again.
To return to the normal display, wait 3 s without pressing any
buttons (exit by timeout).
NOTE: the set point can be set by pressing the SET button (see par.
“Setting the set point (desired temperature value)” page 11).
Temperature Display
The temperature displayed, the unit of measure and the decimal
resolution can be set according to the following parameters: /4, /5
and /6.
r3: select direct/reverse operation
Defines the operating mode of the device:
•
r3=0: direct with defrost. Used to request the activation of the
compressor when the temperature measured by probe 1 rises
above the set point. This mode also includes defrost

to restore all the parameters and return to the original default
values (factory settings), turn the controller off and on again
while holding DOWN and SET, until the display shows "CF". Use
this procedure with extreme car, as it may compromise the
fundamental control settings;
When an alarm is activiated, the display shows the corresponding
message that flashes alternating with the temperature; if fitter and
enabled, the buzzer and the alarm relay are also activiated.
EZY= 0 brings no change
All the alarms have automatic reset (that is, they stop when the
causes are no longer present), except for alarm 'CHt' which has
manual reset (instrument on/off using the UP button or by discon-
necting the power supply).
Pressing the SET button mutes the buzzer, while the code displayed
and the alarm relay only go off when the causes of the alarm have
been resolved. The alarm codes are shown in the able below:

Modifying the Parameters
PARAMETER NAVIGATION
The operating parameters, modifiable using the keypad, are divided
into two types: frequent (type F) and configuration (type C). Access
to the latter is protected by password (default= 22) to prevent
accidental or unauthorized modifications.
Accessing the type F parameters:
•
press the SET button for more than 3 s (if there are active alarms,
mute the buzzer), the display shows the parameter code ‘PS’
(password);
•
•
