easy/easy compact/easy split +030220791 - rel. 3.2 - 13.07.2010
1.3 Main di erences between easy, easy
compact and easy split
Unlike the easy and easy compact models, the easy split models feature
a separate terminal and power board. There are also other di erences,
such as the auxiliary multifunction relay for managing the light output
or a second compressor, and new software functions. The table below
highlights the di erences and indicates the page showing the related
explanation.
• connection cable between terminal and power board (easy split only).
Available in di erent lengths (PEOPZC1500=1.5 m, PEOPZC3000=3.0
m, PEOPZC5000=5.0 m).
1.6 De nitions
Continuous cycle: function that runs the compressor for the set time.
Defrost: function that controls the defrost of the evaporator.
Duty setting: safety function that in the event of control probe faults
starts the compressor at set time intervals.
easy: trademark of the PJEZ(S, X, Y, C, M)* thermostats.
easy compact: more compact and economical version of the easy.
Available in models PJEZ(S, M)*.
easy split: version with separate terminal and power board. Versions
available with (PJEZ*8R***) or without (PJEZ*8I***) RTC, and the power
board can be supplied with (PJEZ*8**5*) or without (PJEZ*8**4*) plastic
case.

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 985 at 25°C for the
PTC, and 10 k 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 K at 25°C), selected by
parameter. Below are some codes of the more common CAREL.

1.5 Accessories
• CAREL IROPZKEY* programming key (for duplicating the parameters);
• CAREL IROPZ485S0 RS485 converter (for the RS485 supervisory
network).
• CAREL USB/RS485 converter CVSTDUMOR0 to interface a RS485
network to a personal computer via the USB port;
• VPM, program downloadable from http://ksa.carel.com. This tool,
running on a computer, can be used to commission the controller,
program the parameters and update the rmware;
• COM TOOL, program downloadable from http://ksa.carel.com. This tool
can be used to program the controller from any PC, save the di erent
con gurations in les that can be recalled during nal programming,
create custom sets of parameters for rapid programming and con gure
the di erent users with password protected access pro les. Connection
to the PC requires the USB/RS485 converter code CVSTDUMOR0;
