Frequency inhibitors and radio equipment operating in a permanent transmission mode in the same frequency band (433 MHz) may impair the normal operation of the ZONING. The system is designed to work on two different frequencies (433.92 and 434.33 MHz) to minimise this type of problem. - Page 3 ZITY, quick installation guide (for air zoning systems)* (*) For other types of installation (boiler, hybrids, VRV, etc.), see the relevant section in the detailed manual.
