Resetting the device by push button
The VAV compact controllers can be reset by push-button:
1. Press button for >10s → LED starts flashing orange
2. Release button while LED still flashes → LED keeps flashing for 3s
3. After those 3s → LED shines red (reset), then green (start-up).
A factory reset by push-button leads to a reset of all parameters as described in the section
“Settings and operating mode” to the OEM default values. Since these values can be set by
the OEM, they are not necessarily the same as the Siemens factory settings.
All other parameters, especially the bus parameters, are reset to Siemens factory settings.
VAV compact controllers can also be reset by the VAV handheld tool AST20 or over bus.
Please refer to the corresponding operating manual / technical basics.
