7. FUNCTIONS “MASTER” PANEL
7.1 On/Off
7.1.1 ON
At power-on, before beginning atomised water production, humiSonic
temporarily runs the Autotest: to check correct operation of the fl oat level
sensor, the humidifi er performs a complete tank fi ll cycle and then a drain
complete cycle.

7.1.2 OFF
Before switching from On to Off , humiSonic temporarily runs the
Shutdown procedure, in which the controller deactivates the control
devices and activates the drain valve. Off status involves a logical OR of
the following:
• digital input;
• keypad;
• time band
• BMS.

7.2 Set point
The control and limit set points are set in the “Set point” quick menu.
Based on the type of control, set the control humidity / temperature
probe set point and the limit humidity probe set point. The following
screens are then used to set the control diff erential and hysteresis.

7.3 Regulation (control)
See chapter “Electrical connections” for the electrical connections to
the “Slave” or “Master” electrical panel, based on the type of control.
The built-in electronic controller on humiSonic features diff erent control
algorithms, which can be selected from the user menu:
On/Off : operation in on/off mode requires the connection of an external
voltage-free contact to input HST (for example, a humidistat, see terminal
block). Unit capacity will therefore be all or nothing, according to the status
of the external contact. The humidistat logic defi nes whether production is
active with the contact closed (N.C.) or with the contact open.

External controller + limit rH%
Capacity modulation is proportional to an external control signal (0 to 1 V,
0 to 5V) and is limited based on the value measured by the limit humidity
probe. This is the typical confi guration for humiSonic installations
connected to a Building Management System that provides a control
signal.
