As we have mentioned on different occasions, this type of installation is not recommended and cost-effective in the short or long term.
Totally inefficient systems due to the lack of compatibility in the different equipment, lack of communication and monitoring among other factors.
In this case we replaced this deficient system with a fully integrated system, excellent performance and warranty!
As I always mention...customers, seek guidance and information from the company you are hiring and the equipment they are proposing to install.
In the long run you are losing money, time and service.
