SC-12: software update to version 2.9.1

Release date: 05.01.2026

We have released a new software version for the ELETOR SC-12 controller, introducing functional enhancements and expanding system configuration options.

🔧 Key changes in version 2.9.1:

1. RH humidity sensor

The RH sensor can now be manually enabled or disabled from the controller menu.

Automatic sensor detection remains active, but users can now disable the sensor manually when needed.

2. V3 output – new application

The previously available gradual heating function (a proportional increase in output voltage as the temperature rises) remains unchanged.

Version 2.9.1 adds a new function for the V3 output:

Control of a second group of butterfly valves in conjunction with a buffer power supply, enabling emergency opening of air inlets in the event of a power failure and increasing the safety of the ventilation system.

Update 2.9.1 is another step towards greater flexibility and safety, and better adapting the SC-12 controller to extensive and demanding ventilation systems.
