Saturn Breeze
APP FOR MOBILE DEVICES
When the app is opened, it scans for nearby inverter
devices by displaying a list of any devices found.
To connect to a device on the list, simply click on its
address/name.
Upon connection, the app may prompt you to enter
the pairing code to the inverter, which is as follows:
123456. The inverter maintains a list of devices pai-
red to it; in the event that the device (smartphone,
tablet, etc.) you are connecting with is not present
within the list, the app will prompt you to enter the
pairing code while otherwise it will not prompt you to
enter any code.
Control panel (Fig.19)
This tab of the application displays a whole range of
information that enables monitoring of the device.
The information displayed is shown in the following

Configuration Parameters (Fig.20)
This tab allows the application to change the opera-
ting parameters of the device. The password 123456
(weak password) must be entered to view the contents
of this tab. The parameters that can be changed are
78

shown in the following table.
Changing the configuration parameters may
affect the optimal operation of the ventilation
system.
Before modification we recommend con-
tacting Munters customer service in order to
avoid malfunctions.
Parameter
Description
Modbus address
Modbus address of the device. Allowable
values: [1;247]
Default: 1
Enable 485
Enabling the 485 bus termination resistor
Allowable values: [0; 1]
0 - Termination resistor not enabled
1 - Termination resistor enabled
Default: 0
Alarm Reset
Reset of alarms.
Allowable values: 0
Enable under stop Enabling minimum speed rotation when the
control voltage is below the minimum value.
Allowable values: [0; 1]
0 - The fan does not rotate when the driving
voltage is lower than the minimum
1 - The fan rotates at minimum speed when
the driving voltage is lower than the mini-
mal one
Default: 0
Acceleration
Acceleration for motion execution
Unit of measurement: rpm/s
Allowable values: [10; Acc. max]
Default: Acc. Max
Deceleration
Deceleration for motion execution
Unit of measurement: rpm/s
Allowable values: [10; Dec. max]
Default: Dec. Max
Boost/Reverse
Enables boost and/or reverse procedures
Configuration
Boost: at power-up the fan will go to ma-
ximum speed and then go to the RPM set
by the controller. Can be used in fans with
Butterfly.
Reverse: when turned off, the fan decele-
rates to a stop, once stopped it will begin
to rotate with opposite direction of rotation
to the standard one so as to "attract" the
butterfly and facilitate closing. Can be used
in fans with Butterfly.
Allowable values: [0; 3]
0 - Boost and Reverse disabled
1 - Boost enabled,
Reverse disabled 2
* 2 - Boost disabled,
Reverse enabled
* 3 - Boost and Reverse both
enabled
Default: 0
*with these parameters, once
the "Off" command is recei-
ved, the fan will automatically
begin to rotate in the opposite
direction for a predetermined
time.
