Firmware for UN-RxxxNMC: Saia PCD Supervisor programmable room controller
Good to know

The UN-RxxxNMC, unitary controller must be programmed with the Saia PCD Supervisor and it's needed to add the .jar modules to the Saia PCD Supervisor installation. The FAQ 102066 describes how to install the .jar modules to the Saia PCD Supervisor installation
It's not possible to program the unitary controller with PG5 or with the QronoX ECS tool
