1. DESCRIPTION
The VX-1005 is a digital temperature controller for refrigeration that has a digital output for actuating an
electronic expansion valve (EEV). In this way, it acts in superheating control in order to optimize the energy
efficiency of the controlled refrigeration system. It's a compact and integrated controller that offers a
complete solution for controlling electronic expansion valves. It has a dedicated control algorithm to run the
cooling process more efficiently without using the pressure transducer.
In addition to estimated superheat control, the instrument controls room temperature, defrosts, ventilation,
lighting and alarms. Room temperature control has an economical setpoint, in addition to fast-freezing
functionality. It adds the control of variable capacity compressors (VCC - Variable Capacity Compressor),
providing a series of benefits to the refrigeration system, such as: reduction of energy consumption, less
temperature oscillation, greater speed in reaching the desired temperature. By configuring its parameters,
it's possible to make the controller compatible with the main brands of variable compressors on the market.
For better use of energy, ventilation can be controlled during the off-cycle of the compressor and use Smooth
Defrost, a defrosting technique that reduces the final temperature of the electrical resistance and the amount
of heat emitted.
It has a serial communication output for integration with Sitrad, an internal real-time clock that allows
programming of defrost events, an intelligent function blocking system, a way to turn off control functions. In
addition, it has a digital filter functionality on the temperature sensor, which aims to simulate a mass increase
in the environment sensor (S1), thus increasing its response time (thermal inertia) and preventing
unnecessary compressor start-ups.
2. SAFETY RECOMMENDATIONS
- Make sure that the controller assembling is done property;
- Make sure that the power supply is turned off and not turned on during controller installation;
- Read this manual before installing and using the controller;
- Use appropriate Personal Protective Equipment (PPE);
- Install the vinyl adehesive protector (included) in installations prone to water splashes, such as refrigerated
counters, etc;
- Installation procedures must be performed only by licensed technicians, subject to codes and regulations.
3. APPLICATIONS
- Beverage displays and Display Cases.

CAUTION
WHERE THE INSTALLATION LOCATION NEEDS TO BE SEALED AGAINST LIQUIDS, THE OPENING IN WHICH THE CONTROLLER
IS TO BE INSTALLED MUST BE NO MORE THAN 70.5x29mm. THE SIDE CLASPS MUST BE SECURED IN SUCH A WAY AS TO
CREATE A TIGHT RUBBER SEAL THAT PREVENTS ANY LIQUIDS ENTERING THE OPENING AND THE CONTROLLER.

7.1. Considerations for installing temperature sensors
- Position sensor S2 - Defrost/suction sensor close to the evaporator output (5cm).
- Due to the position of the defrost sensor at the evaporator output, set the defrost end temperature
(Parameter F44) lower than the setting normally performed.
- Position sensor S3 - Evaporator input sensor, after the electronic expansion valve (10cm).
- Fix the temperature sensors firmly and thermally insulate them so that the room temperature doesn't
interfere with the measurement of the liquid refrigerant temperature.

NEW CONNECTION SYSTEM (QUICK CONNECTOR):
PUSH-IN WIRE CONNECTORS - QUICKLY
Pluggable and Push-in - Quickly
- Push-in Connection:
- Hold the wire close to its end and insert it into the
required opening.
- If necessary, press the button to help make the
connection.
- Ferrule type terminals can be used.
- For the signal connections, the ferrule must be at
In the power connectors the pin must be at least
7mm.
NOTES 1 - Signal Connectors:
- Connections 1 to 20 must use wire of a gauge
between 0.2 and 1,5mm² (26 and 16AWG).
NOTES 2 - Power Connectors:
- Connections 21 to 25 must use wire of a gauge
between 0.2 and 2.5mm² (26 and 12AWG).
