What is Sitrad?

Sitrad is a Full Gauge Controls software for remote management of refrigeration, heating, air conditioning, and solar heating installations. A dedicated engineering team of Full Gauge Controls updates the software constantly, thus meeting the most stringent market requirements. It’s versatile, and provides both local and remote access to installations used in the most different sectors: from supermarket chains, refrigerators and restaurants to hotels, hospitals, laboratories, and residences, among others.


The software continuously evaluates, configures, and stores data on temperature, humidity, time, pressure, and voltage. Therefore, the instruments’ operating parameters may be changed with total safety and accuracy, from anywhere in the world via the Internet, via computer or cell phone.


In addition to a significant reduction in power consumption, the Sitrad provides the user with graphs, reports, and warning messages sent to registered cell phones and e-mails, if variables do not match the established standards.

How much does the Sitrad cost?

Sitrad may be downloaded free from the website.

In which languages is the Sitrad available?

Portuguese, English, Spanish and Turkish.

What do I need to have for the controllers to send information to the software?

The connecting bridge is the CONV32 Interface of the CONV256 Interface, a converter that allows the data exchange between controllers and computer, thus enabling the software to read the data. Its function is to convert the standard serial communication signal RS-232 from the computer to the controllers RS-485 standard. The controllers are connected to the interface, and the interface is connected to the computer through a communication port (COM1, COM2 …). The CONV 32 communicates up to 32 Full Gauge controllers and CONV256 up to 256.

What is the function of the junction box provided with some instruments that communicate with the Sitrad and may be purchased separately?

The junction box connects the controllers to connect the communication network, and has an internal protection that reduces noises from motors, electric cables, and power surges, among others. The junction box come together with the following models: TC-900E Log, MT-512E Log, TC-940Ri plus, PCT-3001 plus, PCT-410E plus and VX-950 plus. It’s also sold separately at your preferred distributor.

How many meters of cable may be used to interconnect the instruments and the computer where the Sitrad module interface is running?

Up to 1,000 m.

How many instruments can be connected to the CONV32 interface?

The CONV32 interface allows the connection of up to 32 Full Gauge controllers with serial output, regardless of model, measurement variable, and amount of sensors that the controller uses.

How many instruments can be connected to the CONV256 interface?

The CONV256 interface allows the connection of up to 256 Full Gauge controllers with serial output, regardless of the model, measurement variable, and amount of sensors that the controller uses.

How many TCP-485 can I use on the same network?

The Sitrad allows the registration of as many ethernet converters as required, provided that they have different IP numbers. Information on how to register the Ethernet Converter can be found in the Sitrad manual:

Is the Sitrad Pro divided into modules?

Yes. Although you don’t notice it, the Sitrad Pro has the Service and Desktop modules in a single installer. The Mobile module is now available for free download on the stores of cell phones with operating systems Android and iOS.

How does each module work?

Both Sitrad Pro modules work together, and that’s why you install a single file on your computer. The Service module manages instruments, users, alarms sent, and logs all information. The Desktop module is the interface through which you access the Service from different locations.

What is the minimum computer configuration for the Sitrad Pro?


  • Windows 7 SP1 or higher
  • Windows Server 2008 R2 SP1 or higher
  • Microsoft .Net framework 4.7.2*
  • 1 GHz processor
  • 3 GB of RAM
  • 4.5 GB hard drive available

*(If not already installed, Sitrad will download at the time of installation)


What is the main difference from Sitrad 4.13?

The Sitrad PRO has a new layout, with an extremely intuitive and friendly appearance, in which all information is even more organized. There is a comparative table between Sitrad 4.13 and Sitrad Pro.  See here.

Will Sitrad 4.13 cease to exist?

No. Sitrad 4.13 will continue to be constantly updated.

Is this software reliable?

Yes. Sitrad Pro is certified for compatibility by Microsoft. When you install the software, however, sometimes Windows will prompt a standard operating system message warning that you are about to open a “non-trusted file”. You can ignore this message and proceed with the installation.

Does Sitrad Pro work with Sitrad Mobile?

Yes. Download from Google Play or the Apple Store, depending on the operating system of your phone and/or tablet.

Does Sitrad Pro work with Sitrad 4.13 Local module?

No. You must choose one of the two versions.

Does Sitrad Pro work with Sitrad 4.13 Remote module?

Yes. You can use both simultaneously on the same computer in this case.

Can I use the information collected by Sitrad 4.13 in Sitrad Pro and vice versa?

Sitrad Pro’s databases are not compatible with Sitrad 4.13. That is, you cannot use the information registered by one version in the other version. But if you want, you can keep both versions installed for when you need to refer to old data.

How many Full Gauge Controls instruments does the Sitrad Pro support?

The Sitrad Pro capacity is unlimited. However, pay attention to the maximum capacity of each converter interface used in the installation. E.g., the Conv 32 model supports up to 32 instruments.

Can I repeat the RS-485 Network address?

Yes, provided that the instruments with repeated addresses are in different interfaces (converters).

Do I need to be logged into a Windows account?

No, the Sitrad Pro runs as a Windows service, i.e., it’s already working even before you log in.

Can I view more than one server at the same time?

Yes, the Sitrad Pro’s Viewer Mode allows you to view several servers on one screen.

Does Sitrad Pro need port unlocking on the modem for remote access? What doors are needed?

Yes, however, Sitrad Pro attempts to automatically release ports by UPnP protocol if the network modem supports such a protocol and is active. To activate, refer to the manual of your modem. Sitrad Pro in its current version has remote management by computer only and to access it will need to release port 8001.

Is Sitrad Pro compatible with all Full Gauge instruments?

The Sitrad Pro is currently compatible with the products listed here.

What should I do when the message "invalid or corrupted .Cab file" appears?

If the message “invalid or corrupted .Cab file” appears when installing Sitrad Pro, it means that Windows was unable to validate the digital certificate during this process.
The first time Windows validates a new certificate, it needs to download information from the certifying agency that issued the digital document on the Internet.
In case you are without internet connection or there is some type of block, you must manually download and install the digital certificates below:

What is an API and how can I use it?

API (Application Programming Interface) is a type of “bridge” that connects applications. They provide an agile and secure integration between systems developed in totally different languages.

The Sitrad Pro’s API is available through a web service based on the REST standard with data exchange in JSON format and is accessible on the machine where Sitrad service is installed.

Through it, an application can request Sitrad Pro to report the current temperature of an instrument, its temperature history, alarm information and much more. It is also possible

to use the functionality, for example, to modify the control temperature (setpoint) of an instrument.

All the possibilities of integration between applications are available for consultation through documentation. One way to access the documents is through the address of our demo server at (the browser may warn you that the site’s certificate is invalid because it is a self-signed certificate, but you can accept it and continue browsing).

More documents, activation instructions and access to documentation for other integration forms and examples can be found at
