Note:
The cables of the controller are pre-connected. chap. 1.2 is for informa-
tion purposes only. Make sure the hydraulic system is properly grounded!
Note:
For more details about the initial commissioning procedure see chap. 2.2.
Mains and sensor cables are already connected to the device.
Additional temperature sensors (S3 to S10) can be connected to the terminals
S3 … S10 and GND (either polarity).
The controller is supplied with power via a mains cable. The power supply of the
device must be 100 … 240 V~ (50 … 60 Hz).
The mains connection is at the terminals:
Neutral conductor N
Conductor L
Conductor L' (L' is not connected with the mains cable. L' is a fused contact per-
manently carrying voltage).

2 Heat transfer controller commissioning
2.1 Factory menu
In the factory menu, the controller can be adjusted to the heat transfer module in
which it is integrated (SUS Midi, Maxi). In order to do this, the parameter Hydraulic
variant must be adjusted.
WARNING! Scald danger! System damage!
Adjusting a wrong hydraulic variant can lead to inadmissibly high
water temperatures.
Î
The hydraulic variant must be adjusted by authorised
personnel only!
The hydraulic variant determines the range of available functions and parameters
of the controller according to the equipment of the heat transfer module.
2.2 Running the commissioning menu
The commissioning menu is run after the first connection and after every reset. It
will request the following basic adjustments:
• Menu language
• Time
• Date
• System variant
• Hot water set temperature
• Maximum speed of the primary pump
• Maximum speed of the secondary pump
When the last item Save at the end of the commissioning menu is selected, a safety
enquiry appears. If the safety enquiry is confirmed, the adjustments are saved.
For further information about the commissioning menu see page 14.
