Planning and use
This section contains tips and application examples for practical application of the device.
7.1
Operating mode
The ambient temperature controller has he following four operating modes:
For switching between the operating modes switching telegrams (parameter “operating mode switching”: “1 bit
(3x)”) or 1-byte value telegrams (parameter “operating mode switching”: “1 byte (2x)”) are used (see also drawings
of operating modes on page 83, Section Operating mode switching).
7.1.1 Operating mode switching 1 bit
The frost/heat protection has the top priority, i.e. in this case switching to a different operating mode is disabled.
Frost/heat protection must be disabled first, e.g. by closing an open window. Night mode has the next higher priority,
followed by comfort mode. If none of the above three operating modes are enabled, the ambient temperature
controller is in standby mode.
7.1.2 Operating mode switching 1 byte
When switching operating mode via 1 byte an object is available. When, for example, a comfort telegram is received,
the room thermostat switches to comfort mode. If a night telegram is received, the ambient temperature controller
switches to night mode. This object is controlled, for example, by time switches.
The following applies to the 1-byte communication object:
