Omron 20C1AR - A V2 ZEN heating control boiler sequencing application

[Gattaca 0]

Hi All

Got a problem to with this PLC (Omron 20C1AR A V2) when programme on ZEN, pretty simple question, get 10 zone as 10 input feed in in I0-I9, a) every single one on, output Q1 on to call one boiler. 2) every 3 or more zones on (among the I0-I9), output Q2 is on to call two boiler to work together.

Seems there is no way to programme this simple function in Zen? try to use counter but can't work it out.
