3.9 Electrical connect. to the “Main” panel
Below is the connection diagram between the terminal block on the
“Main” electrical panel and the terminal block on the humidifier.
Depending on the type of signal, atomised water production can be
enabled and/or managed in different ways.

3.10 Control types
To enable all types of control:
1. Humidifier terminal block: keep the factory-set jumper on terminals
COM and ONOFF;
2. Terminal block on the “Main” electrical panel: Jumper terminals
ONOFF and COM (enable)
ON/OFF CONTROL (humidistat or remote contact):
“Main” electrical panel terminal block
• Connect terminals HST and COM to a humidistat or remote contact
(voltage-free contact);
• Set Fa01: Regulation type = On/Off.
EXTERNAL PROPORTIONAL CONTROLLER (modulating action):
“Main” electrical panel terminal block
• Connect the COM and 0-10V terminals to a 0-10V external controller,
or the COM and M_PB (main probe) terminals to a 0-1V / 0-5V external
controller
• Set Fa01: Ext. regulator;
• Set parameter Fa04 for the type of signal from the external controller:
Probe type = 0 to 1V, 0 to 5V / 0 to 10V.
EXTERNAL PROPORTIONAL CONTROLLER (mod. action) + limit rH%:
“Main” electrical panel terminal block
• Connect the COM and 0-10V terminals to a 0-10V external controller,
or the COM and M_PB (main probe) terminals to a 0-1V / 0-5V external
controller
• Connect the COM, +V and L_PB (limit probe) terminals to a 0-1V / 0-5V
active humidity probe;
• Set Fa01: Ext. regulator + limit rH%;
• Set parameter Fa04 for the type of signal from the external controller:
Probe type = 0 to 1V, 0 to 5V / 0 to 10V;
• Set parameter Fa06 for the type of signal from the limit probe: Probe
type = 0 to 1V, 0 to 5V.
TEMPERATURE CONTROL
“Main” electrical panel terminal block
• Connect the COM, +V and 0-10V terminals to a 0-10V temperature
probe; or the COM, +V and M_PB (main probe) terminals to a 0-1V /
0-5V / 0-10V temperature probe; or the COM and M_PB terminals only
to an NTC probe;
• Set Fa01: T probe;
• Set parameter Fa04 for the type of signal from the temperature probe:
Probe type = 0 to 1V, 0 to 5V, 0 to 10V, NTC.
Note: if using the NTC probe, remove the sheathed resistor placed
between terminals B7-GND on the electronic board
TEMPERATURE CONTROL + limit rH%
“Main” electrical panel terminal block
• Connect the COM, +V and 0-10V terminals to a 0-10V temperature
probe; or the COM, +V and M_PB (main probe) terminals to a 0-1V /
0-5V temperature probe; or the COM and M_PB terminals only to an
NTC probe;
• Connect the COM, +V and L_PB (limit probe) terminals to a 0-1V / 0-5V
humidity probe;
• Set Fa01: T probe +limit rH%;
• Set parameter Fa04 for the type of signal from the temperature probe:
Probe type = 0 to 1V, 0 to 5V, 0 to 10V, NTC.
• Set parameter Fa06 for the type of signal from the limit probe: Probe
type = 0 to 1V, 0 to 5V.
Note: : if using the NTC probe, remove the sheathed resistor placed
between terminals B7-GND on the electronic board
HUMIDITY CONTROL
“Main” electrical panel terminal block
• Connect the COM, +V and 0-10V terminals to a 0-10V humidity probe;
or the COM, +V and M_PB (main probe) terminals to a 0-1V / 0-5V
temperature probe;
• Set Fa01: probe rH%;
• Set parameter Fa04 for the type of signal from the humidity probe:
Probe type = 0 to 1V, 0 to 5V / 0 to 10V.
HUMIDITY CONTROL + Limit %rH
“Main” electrical panel terminal block
• Connect the COM, +V and 0-10V terminals to a 0-10V humidity probe;
or the COM, +V and M_PB (main probe) terminals to a 0-1V / 0-5V /
0-10V temperature probe;
• Connect the COM, +V and 0-10V terminals (limit probe) to a 0-1V / 0-5V
humidity probe;
• Set Fa01: probe rH% + limit rH%;
• Set parameter Fa04 for the type of signal from the humidity probe:
Probe type = 0 to 1V, 0 to 5V;
• Set parameter Fa06 for the type of signal from the limit probe: Probe
type = 0 to 1V, 0 to 5V.
