It will be possible to set the Modbus address of each inverter installedon compressors. This function is supposed to be activated in case of compressor replacement. The page willalso contain the Modbus setup parameters like baud rate, parity etc.Setpoint/Sub-Menu Default Range DescriptionBaud Rate= 19200 4800, 9600, 19200, 38400 Modbus communication speedParity= None None, Odd, Even ParityTwo Stop Bits= No No, Yes Number of stop bits485 Resistance= Active Active, Passive RS485 Termination resistanceSet Inv1 Fltr= Hold Hold, Exec Command to enable communication filter on the compressor 1Set Inv2 Fltr= Hold Hold, Exec Command to enable communication filter on the compressor 24.2.4 PumpsThis page contains the settings to define the operation of the primary/backup pumps, the running hours ofeach pump and all parameters to configure the behavior of the pump driven with an inverter.Setpoint/Sub-Menu Default Range DescriptionTZ / TZB VZEvp Pmp Ctrl= #1 Only #1 Only #1 Only, #2 Only, Auto,#1 Primary, #2 PrimarySet number of Evaporator pumps operational and whichpriority.Evap Recirc Tm= 30s 30s 0…300s Water recirculating timerEvap Pmp 1 Hrs= 0h 0h Running Hours Evaporator Pump 1 (if present)Evap Pmp 2 Hrs= 0h 0h Running Hours Evaporator Pump 2 (if present)Speed 1= 80% N/A 0-100% Speed when the input Double Speed Switch is openCnd Pump Ctrl= N/A #1 Only #1 Only, #2 Only, Auto,#1 Primary, #2 PrimarySet number of Condenser pumps operational and whichpriority.
