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

3.10 Control types
To enable all types of control:
1. Humidifi er terminal block: Jumper terminals COM and ONOFF;
2. Terminal block on the “Master” electrical panel: Jumper terminals
ONOFF and COM (enable)
ON/OFF CONTROL (humidistat or remote contact):
“Master” 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):
“Master” electrical panel terminal block
• Connect terminals COM and M_PB (main probe) to an 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.
EXTERNAL PROPORTIONAL CONTROLLER (mod. action) + limit rH%:
“Master” electrical panel terminal block
• Connect terminals COM and M_PB (main probe) to an external controller;
• 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;
• Set parameter Fa06 for the type of signal from the limit probe: Probe
type = 0 to 1V, 0 to 5V.
TEMPERATURE CONTROL
“Master” electrical panel terminal block
• Connect terminals COM, +V and M_PB (main probe) to a temperature
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, NTC.
TEMPERATURE CONTROL + limit rH%
“Master” electrical panel terminal block
• Connect terminals COM, +V and M_PB (main probe) to a temper. probe
and terminals COM, +V and L_PB (limit probe) to an active 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, NTC.
• Set parameter Fa06 for the type of signal from the limit probe: Probe
type = 0 to 1V, 0 to 5V.
HUMIDITY CONTROL
“Master” electrical panel terminal block
• Connect terminals COM, +V and M_PB (main probe) to a humidity 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.
HUMIDITY CONTROL + Limit %rH
“Master” electrical panel terminal block
• Connect terminals COM, +V and M_PB (main probe) to a humidity
probe and terminals COM, +V and L_PB (limit probe) to an active
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.
FINAL CHECKS
The following conditions represent correct electrical connection:
• mains power to the humidifi er corresponds to the rated voltage;
• a mains disconnect switch has been installed so as to be able to
disconnect power to the humidifi er;
• terminals COM – ONOFF on the humidifi er terminal block are jumpered
or connected to a contact to enable operation; if the humidifi er is
controlled by an external controller, the signal earth is electrically
connected to the controller earth.
