9.9 PARALLEL OPERATION
Up to 5 humidifiers can be connected in parallel.
Byconfiguringandsettingthefirsthumidifieronly(MASTER),theothers(SLAVES)willfollowtheoperationofthefirsthumidifier
by replicating it precisely (parametrizations are not replicated if they are changed on the MASTER).
Toactivatethisoperatingmode,youneedto:
•
SetonehumidifierasMaster,bysetting
CFG = 5...9;
•
