ACS and ETS require an interface:
● KNX interface (e.g. Siemens N148…)
● OCI702 USB-KNX interface
Set the control sequence via parameter P001 depending on the application.
Factory setting:
4-pipe, chilled ceiling and el. heater,
6-port ball valve applications, and 2-
stage
Recalibrate the temperature sensor (internal and external), if the room temperature
displayed on the thermostat does not match the room temperature measured (after
min. 1 hour of operation). To do this, change parameter P006.
We recommend to review the setpoints and setpoint ranges (P011, P013…P016,
P019, P020) and change them as needed to achieve maximum comfort and save
energy.
The programming mode helps identify the thermostat in the KNX network during
commissioning.
Touch both the left and right buttons simultaneously for 6 seconds to activate
programming mode, indicated on the display by PROG.
Programming mode remains active until thermostat identification is complete.
Assign complete KNX address (area, line and device) via:
● HMI or Siemens smartphone application PCT Go by setting parameters P898
(area address), P899 (line address) and P900 (device address)
● ACS or ETS (P900: device address)
Set the device address to 255 to deactivate the communication (no exchange of
process data).
Use ETS to assign the KNX group addresses of the thermostat's communication
objects.
Each device has a unique KNX serial number on the rear.
An additional sticker with the same KNX serial number is enclosed in the package.
This sticker is intended for documentation purposes of installers.
