Table 7: Modbus Addresses (Continued)
Function Description Address Details
Force Drain When written to (FF), will interrupt the
humidification process and activate the
humidifier drain valve. After 20 minutes
the controller will reset this value (00).
After a microprocessor reset, the default
setting shall be (00)
40005 255 will start the process, 0 will be
accepted, to clear if the request has not
been cleared itself
Reset Run
Hour
Counter Resets the humidifier controller’s run
hour counter to zero hours 40006 255 will start the run hours counter
process. 0 will be accepted to clear the
run hours counter.
Set Modbus
address Change the humidifier controller’s
MODBUS address. Range is 1-247. This
setting shall be non-volatile with a
default setting of 1. 40201 The value changes will only take effect
following a hardware reset of the control
board.
Set Modbus
Baud rate Changes the humidifier’s baud rate.
Range is 4800, 9600, and 19200 B/sec.
This setting shall be non-volatile with a
default value of 9600 B/sec. 40202 The value changes will only take effect
following a hardware reset of the control
board
Set Modbus
parity Change the humidifier controller’s
MODBUS parity. Range is None, Even,
Odd This setting shall be non-volatile with
a default setting of Even. 40203 The value changes will only take effect
following a hardware reset of the control
board

Unit phase Required by the control board for current
and capacity calculations 40207 Bit Allocation
Single phase = 1
Three phase = 2
Three phase (6 electrode) = 4
Electrode
current The value of the electrode current in
Amps 30104 Hex value representing the humidifies
current in amps Resolution: 0.10 amps
Example: 015F (hex) = 35.1 Amps
