Installation and commissioning
First filling
Upon commissioning / restart of the heating system for initial filling / refill.
The device operates by factory default or with preset values.
Upon initial commissioning
►
Confirm „Initial commissioning” in the menu by pressing “YES“. You will be
asked to indicate the basic parameters regarding the size of the installation,
water conditioning and system pressure. When pressing “NO“, the device
will switch to the main menu for all basic parameter settings.
For refills:
►
Select “initial filling” in the menu.
►
Start the initial filling by simultaneously pressing the buttons
and for
3 s in the main menu.
Note: the system pressure must not have reached the desired value yet.
The initial filling ends once the desired pressure value has been reached.

Automatic refill
As permanent operating mode after commissioning.
The device operates by factory default parameters. However, it is possible to
modify settings and optimize the parameters of the installation. This operating
mode is used for the automatic filling and monitoring of the heating system.
The refill process starts automatically once the pressure within the installation
is below the pre-set lower reference pressure (system pressure-differential
pressure). A manual refill in this mode is not possible.
The refill process will end automatically once the pressure within the installation
reaches the pre-set upper reference pressure (system pressure).
One-time manual refill
Manual refill before reaching the lower reference pressure.
The device continues to operate with pre-set limit values. Once the manual
refill is completed, the device switches to automatic filling. This operating mode
makes sense if a refill is desired, yet without having reached the lower reference
pressure that triggers automatic refills
►
Start the refill process by simultaneously pressing the buttons
and
for 3 s in the main menu.
Note: the system pressure must be below the upper reference pressure
.
The one-time manual refill process automatically ends once the pressure within
the installation has reached the pre-set upper reference pressure (system
pressure).
