9.9 PARALLEL OPERATION
Up to 5 humidifiers can be connected in parallel.
Byconfiguringandsettingthefirsthumidifieronly(MASTER),theothers(SLAVES)willfollowtheoperationofthefirsthumidifier
by replicating it precisely (parametrizations are not replicated if they are changed on the MASTER).
Toactivatethisoperatingmode,youneedto:
• SetonehumidierasMaster,bysettingCFG = 5...9;
• SetalltheotherhumidiersasSlave,bysettingCFG=10oneachhumidier;
• Connect the analogue input IA1ontheMasterhumidier;
• Connect the digital output Out1 ofeachhumidiertothedigitalinputID2ofthenexthumidier.
