Valve
Setting the type of valve automatically denes all the control parameters based
on the manufacturer’s data for each model. In Manufacturer programming
mode, the control parameters can then be fully customised if the valve used is
not in the standard list. In this case, the controller will detect the modication
and indicate the type of valve as “Customised”.

Note: select Valve = disabled if Main control = I/O expansion for pCO
to prevent the EEV motor error from being displayed. I/O expansion for pCO
control can be selected at the end of the commissioning procedure, by
entering programming mode.
Important:
• two CAREL EXV valves connected together must be selected if two
CAREL EXV valves are connected to the same terminal, to have parallel or
complementary operation;
• as described, control is only possible with CAREL EXV valves;
• NOT all CAREL valves can be connected: see paragraph 2.5.
Pressure/refrigerant level probe S1 & S3
Setting the type of pressure probe S1 for driver A and S3 for driver B denes
the range of measurement and the alarm limits based on the manufacturer’s
data for each model, usually indicated on the rating plate on the probe.
Select “CAREL liquid level” and connect the CAREL oat level sensor to manage
the following functions:
- evaporator liquid level control with CAREL sensor;
- condenser liquid level control with CAREL sensor.
For example, connecting two CAREL liquid level probes, one to S1 and one to
S3, allows independent control of two refrigerant liquid levels.
See the chapter on “Control”.

(*) for programmable positioner. See chapter “Control”.
Important: if two pressure probes S1 and S3 are installed, these must
be the same type. A ratiometric probe and an electronic probe cannot be
used together.
Note: in the case of multiplexed systems where the same pressure
probe is shared between the twin1 and twin2 controllers, choose the normal
option for driver A and the “remote” option for the remaining drivers.
Example: to use the same pressure probe P1 for driver A and B: 4 to 20 mA,
-0.5 to 7 barg
For driver A on the twin 1 controller select: 4 to 20 mA, -0.5 to 7 barg.
For driver B on the twin 1 controller and for driver A and B on the twin 2
controller select: remote 4 to 20 mA, -0.5 to 7 barg.
The connection diagram is shown in paragraph 2.6
Note:
• the range of measurement by default is always in bar gauge (barg). In
the manufacturer menu, the parameters corresponding to the range of
measurement and the alarms can be customised if the probe used is not
in the standard list. If modifying the range of measurement, the controller
will detect the modication and indicate the type of probe S1 or S3 as
“Customised”;
• the software on the controller takes into consideration the unit of measure.
If a range of measurement is selected and then the unit of measure is
changed (from bars to psi), the controller automatically updates the limits
of the range of measurement and the alarm limits. By default, the main
control probes S2 and S4 are set as “CAREL NTC”. Other types of probes can
be selected in the service menu;
• unlike the pressure probes, the temperature probes do not have any
modiable parameters relating to the range of measurement, and
consequently only the models indicated in the list can be used (see
the chapter on “Functions” and the list of parameters). In any case, in
manufacturer programming mode, the limits for the probe alarm signal
can be customised.

Setting the main control denes the operating mode for each driver.
