USER MANUAL
S9
Functioning setting set:
S9=0 ON-OFF
(Enabling ON between clamps 24 and 25)
S9=1 (INTEGRATED HUMIDISTAT)
PROPORTIONAL WITH 4-20mA PROBE
Operation with integrated humidistat.
4-20mA ambient humidity probe connected to analogical
input no. 1 (clamps 14-15).
S9=2 PROPORTIONAL
REFERRED
TO
0-10V
EXTERNAL SIGNAL
0-10V reference signal connected to analog input no.2
(clamps 16-17).
S9=3 (INTEGRATED HUMIDISTAT)
PROPORTIONAL WITH 4-20mA PROBE AND
4-20mA PROBE IN AIR DUCT
4-20mA ambient humidity probe connected to the analogue
input no.1 (clamps 14-15).
4-20mA humidity
probe in air duct connected to the
analogue input no.4 (clamps 21-22).
S9=4 PROPORTIONAL
REFERRED
TO
0-10V
SIGNAL AND 4-20mA PROBE IN AIR DUCT
0-10V reference signal connected to analog input no.2
(clamps 16-17).
4-20mA humidity
probe in air duct connected to the
analogue input no.4 (clamps 21-22).
S9=5 (INTEGRATED HUMIDISTAT)
PROPORTIONAL WITH 0-10V PROBE
0-10V ambient humidity probe connected to the analogue
input no.2 (clamps 16-17).
S9=6 (INTEGRATED HUMIDISTAT)
PROPORTIONAL WITH 0-10V PROBE AND
0-10V PROBE IN AIR DUCT
0-10V ambient humidity probe connected to the analogue
input no.2 (clamps 16-17).
0-10V humidity
probe in air duct connected to the analogue
input no.5 (clamps 22-23).
S9=7 (INTEGRATED THERMOSTAT)
Operation with integrated thermostat (call of heat ON/OFF)
and NTC temperature probe connected to the analogue
input no.3 (clamps 18-19).
S9=8 PROPORTIONAL REFERRED TO VALUE
SENT ON RS485 (0-100%)
Steam production request reference (0-100%) from RS485
line (Modbus). To set steam production, use register 1537.
N.B. – The commands to force water discharge and produce
steam have a time-out of 1 minute; if during this period the
command is not sent again on Modbus, at the end of this
time the steam production will be set to zero and the drain
pump will be disabled. This secures the humidifier in case
of accidental disconnection of the communication network.
S9=9 (INTEGRATED THERMOSTAT)
PROPORTIONAL WITH NTC PROBE
Operation with integrated thermostat.
NTC temperature probe connected to the analog input no.3
(clamps 18-19).
Attention: the enabling between clamps 24 and 25 must be given for
any type of selected functioning.
