Page 22: Operation Of Two Units In Master/Slave Mode
7 - WATER CONNECTIONS 7.5 - Operation of two units in master/slave mode The control of a master/slave assembly is in the entering water and does not require any additional sensors (standard configuration). It can also be located in the leaving water. In this case two additional sensors must be added on the common piping. All parameters, required for the master/slave function must be configured using the MST_SLV menu. -
