Remote operating and fault indication “Z401” and “Z401S”
By means of 4 potential-free relay contacts, the remote operating and fault
indication PCB (Z401: standard version, Z401S: wire breakage safe version)
allows the connection of remote indicators displaying the following stages
of operation: “standby”, “humidification in progress”, “maintenance due”
and “error”.
Note: The remote operating and fault indication PCB is supplied with
separate instructions.
Serial interfaces RS232 “Z404” or RS485 “Z405”
The serial interface (RS232 or RS485) is used to transmit operational data
from the Condair Dual Hybrid Humidifier to a PC or a building control
system.
Note: It is up to the customer to develop installation-specific software. Information
on the communication parameters and the data format supported
by the interface is available from your Condair supplier.
