system controls the zones via control keys for the zones on the panel.

indicates the zone is "switched-on"; gently press the zone key when the indicator lamp is on can

make the indicator lamp go off, and it indicates the shutdown of the zone) .For control of zones

whose number is above 20, please press zone selection key first, and then the key for "+1～+20".

Zone scope selection key "1～20" is used for controlling the first to 20th zones.

Zone scope selection key " 21～40 " is used for controlling the 21st to 40th zones.

Zone scope selection key " 41～60 " is used for controlling the 41st to 60th zones.

Zone scope selection key " 61～80 " is used for controlling the 61st to 80th zones.

Zone scope selection key " 81～100" is used for controlling the 81st to 100th zones.
