Important: each of the features should be checked for the model
in question.
1.2 Models
The easy and easy compact controllers dier as regards operation, and
the number inputs and outputs. easy split models feature a separate
terminal and power board. PQEZ* controllers are specically designed for
use in applications with ammable refrigerants.
easy models:
P(J,Q)EZS (0, 1, 6, 7)*; P(J,Q)EZ(X, Y)*; P(J,Q)EZC* controllers and P(J,Q)
EZM(0, 1, 6, 7)* thermometer only.
easy compact models:
P(J,Q)EZS(N, P)* controller and PJEZM(N,P)* thermometer only.
easy split models:
PJEZ*8**** controllers with one relay used for the light output.
Models and features
S models P(J,Q)EZS*
The ideal solution for the management of static refrigeration units (that is,
without fan on the evaporator), operating at normal temperature (above 0
°C). This model, in fact, performs the functions of thermometer, displaying
the temperature of the unit, and electronic thermostat, activating the
compressor (or the solenoid valve in the case of multiplexed units) so as
to maintain the required temperature. In addition, it features compressor
protection algorithms and automatic defrost function by shutting down
the compressor.
X and Y models P(J,Q)EZX*, P(J,Q)EZY*
These are designed for the management of static units operating at
low temperature (that is, below 0ºC), which require active defrost using
electric heaters or the injection of hot gas. The P(J,Q)EZ(Y,X)*, in fact,
as well as working as a thermometer and a thermostat (like the P(J,Q)
EZS), also manages the defrost actuator. The frequency and duration
of the defrost can be set. The end defrost can occur according to the
temperature reached (connecting a probe to the evaporator) or by time.
In addition these models feature two probe inputs, for the control probe
(room), the defrost probe, and a digital input (this can also be congured
as a probe). There are two outputs, for controlling the actuator (compressor
) and the defrost . Models P(J,Q)EZY and P(J,Q)EZX dier in that:
• P(J,Q)EZY has relays that are electrically connected together;
• P(J,Q)EZX has independent relays.
C models P(J,Q)EZC*
The most complete solution for low temperature ventilated units, with
three relays for complete control of the compressor, fan and defrost
functions. The three relays are included in the very compact case in the
versions with 230 V or 115 V power transformer, without compromising
the performance or reliability of the product.
M models P(J,Q)EZM*
Solution for simply measuring the temperature.

1.4 NTC and PTC probes
All easy and easy compact models use PTC and NTC probes conforming
to the CAREL standard, with resistance values of 985Ω at 25°C for the
PTC, and 10 kΩ for the NTC. The type of probe installable depends on
the model (order code). The easy split models, on the other hand, only
use NTC and high temperature NTC probes (50 KΩ at 25°C), selected by
parameter. Below are some codes of the more common CAREL.

Warnings:
Avoid installing the boards in environments with the following
characteristics:
• relative humidity greater than 90% or where there is condensation;
• strong vibrations or knocks;
• exposure to continuous water sprays;
• exposure to aggressive and polluting atmospheres(e.g.: sulphur and
ammonia fumes, saline mist, smoke) so as to avoid corrosion and/or

Panel installation from the front using screws (Fig. 2.c)
• 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);
• if the board is installed in an electrical panel with metal cabinet, allow
at least 10 mm distance between the cabinet and any point on the
board (rear, edges and assembly holes);
• the probe and digital input connections must be less than 10 m long,
adopt suitable measures to separate the cables for compliance with
immunity standards;
• suitably fasten the output connection cables to avoid contact with
extra low voltage components.
• 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);

2.2 Electrical connections
Warnings:
• the electrical connections must only be completed by a qualied
electrician;
• a power supply other than the type specied may seriously damage
the system;
• on easy split models supplied with plastic case, given the high
maximum power supply current (16 A), the unit may heat up: in this
case, make sure the maximum temperature allowed is not exceeded.
See the table of technical specications;
• separate as much as possible the probes and digital input signal
cables from the cables carrying inductive loads and power cables to
avoid possible electromagnetic disturbance. Never lay power cables
(including the electrical cables) and probe signal cables in the same
conduits. Do not install the probe cables in the immediate vicinity of
power devices (contactors, circuit breakers or similar);
• reduce the path of the probe and sensor cables as much as possible,
and avoid spiral paths that enclose power devices. The probes must
be connected using shielded cables (minimum cross-section of each
wire: 0.5 mm2);
• avoid direct contact with internal electronic components;
• connection errors (and connections other than those indicated in this
manual) may involve danger to the safety of the users and cause faults
on the instruments and the components connected;
• t the unit with all the electromechanical safety devices required to
guarantee correct operation and the complete safety of the user.
Information:
• the probes can be installed up to a maximum distance of 30 m from
the controller (10 m for easy split). To extend the distance of the probes,
use cables with a minimum cross-section of 1 mm², shielded where
possible. In this case, the shield must be connected to the common of
the probe. Do not earth the other end of the shield (the sensor end);
• only use IP67 probes as end defrost probes; place the probes with the
vertical bulb upwards, so as to assist the drainage of any condensate.
The thermistor temperature probes (NTC or PTC) have no polarity, so
the order of connection of the ends is not important;
• use cable ends suitable for the corresponding terminals. Loosen each
screw and insert the cable ends, then tighten the screws. When the
operation is completed, slightly tug the cables to check they are
suciently tight.
The connections of the inputs and outputs, depending on the models,
may be made:
• using traditional screw terminals;
• using plug-in terminals with screw cable connection blocks;
• using plug-in terminals with crimped cable connection blocks.
• using plug-in terminals, which signicantly simplify the connection
of the instrument both during installation and maintenance. This also
avoids connection errors, as there are three connection blocks with a
dierent number of pins.
Connect the inputs and the outputs following the diagram shown on the
instrument label.
For the 12 Vac versions:
• if the power supply available is mains, a safety transformer is required
to ensure double insulation between the power supply and the very
low voltage electronics. If required, a fuse must be installed in series
with the primary (32 mAT for code TRA12VDE00). The transformerinstrument connection must be as short as possible;
• if the power supply available is already low voltage, but not 12 Vac,
a suitable adapting transformer must be used: double insulation
between the primary and secondary and denition for surge on the
primary to the appropriate level (2000 V for applications in industrial
environments.
• as double insulation cannot be guaranteed between the power supply
connectors and the relay outputs, only use loads powered at safety
extra low voltage (eective rating up to 42 V).
The voltage supplied to these terminals (see the wiring diagrams) must
correspond, within the specied tolerances, to the value shown on the
instrument connection label. The insulation of the instrument, for versions
with mains power supply (230 Vac and 115 Vac), is reinforced. The versions with
12 Vac/Vdc power supply, on the other hand, do not feature such insulation.
For easy split:
Refer to the following wiring diagram;
• power supply L, N, PE: use cables with a suitable cross-section for the
load (2.5 mm2 for current ratings up to 16 A and 4 mm2 for current
ratings up to 24 A);
• load connection: terminate with 6.3 mm female spade contacts, cable
cross-section 2.5 mm2 for current ratings up to 16 A;
• use:
– cables with max. operating temperature at least 90 °C
– spade terminals with max. operating temperature at least 100 °C
• internal jumpers for power supply to loads as per the previous point;
• probe and digital input connections with 0.5 to 1.5 mm
2
cables;
• terminal connection using specied cables.
