Art. No. SC 1000 KNX
i Frequent draughts in a room can cause unintentional activation/deactivation of frost
protection when the automatic frost protection mode is active, and if the parameterized
temperature decrease is not low enough. Therefore switching into the frost/heat protection
mode by window contacts should generally be preferred to the automatic option.
Additional information on the operating mode after a reset
In the ETS, it is possible to use the "Operating mode after reset" parameter in the "Room
temperature control -> Controller general" parameter node to set which operating mode should
be activated after bus voltage recovery or re-programming by the ETS. The following settings
are possible...
- "Comfort operation" -> The comfort mode will be activated after the initialisation phase.
- "Standby mode" -> The standby mode will be activated after the initialisation phase.
- "Night operation" -> The night mode will be activated after the initialisation phase.
- "Frost/heat protection operation" -> The frost/heat protection mode will be activated after
the initialisation phase.
- "Restore operation mode before reset" -> The mode set before a reset according to the
operating mode object or channel-/push button function (normal priority) will be restored
after the initializing phase of the device. Operating modes set by a function with a higher
priority before the reset (Forced, Window status, Presence status) are not effected.
The operating mode objects will be updated after a reset.
i Note on the "restore operation mode before reset" setting:
Frequent changing of the operating mode (e. g. several times a day) during running
operation can adversely affect the life of the device as the read-only memory (EEPROM)
used has been designed for less frequent write access events only.
