    4.1.1 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....

    The second object )"operating mode switching omo") may "overwrite" the first temporarily. This means, for example, if a frost/heat protection telegram is received, the ambient temperature controller switches to frost or heat protection mode. If the frost or heat protection is reset by the receipt of...

    4.2 temperature measurement the ambient temperature controller with display can record the temperature with an internal sensor. Values can also be received from an external sensor or an outside temperature sensor via communication objects. Receipt of the values can be monitored and possibly calibrat...

    The room temperature controller will stop controlling and will send a predefined control value ("control value for temperature measurement error") to prevent the room from overcooling or overheating. The control value is transmitted until the ambient temperature controller receives a temperature tel...

    4.3 controller the ambient temperature controller can be used for heating only, cooling only or for heating and cooling. If the ambient temperature controller is to be used for heating and cooling, it can switch automatically from heating to cooling and cooling to heating. The controller automatical...

    4.3.4 fan coil if fan coil is selected under "control types", the control values are output in the same way as described at continuous controllers. A fan coil also has the option of controlling fan stages using a 1-byte or three 1-bit communication objects with a fan coil actuator. Switching fan sta...

    4.4 setpoints the ambient temperature controller can be operated with dependent or individual setpoints. The two options are explained in more detail below. 4.4.1 dependent setpoints sollwerte heizen sollwerte kühlen frost/hitzschutz- betrieb regler fordert keine leistung (stellgröße = 0) komfort- b...

    "setpoint heating" is the default setting. In regions where the cooling function is more important, it is recommended that you change this parameter to "setpoint cooling". This makes it easier to set the ambient temperature controller and raise the cooling setpoints (standby temperature cooling and ...

    4.4.3 minimum distance the adjustable parameter "minimum distance between heating and cooling" is enabled with both dependent and individual setpoints. The minimum distance is always between "heating setpoint comfort mode" and "cooling setpoint comfort mode". It acts as a buffer zone to prevent the ...

    4.5 fan coil general ventilator convectors, also referred to as blower convectors or fan coil units, are used for decentralised heating and cooling. They are mounted in the room and supplied by a central heating and cooling system. A distinction is made between 2-pipe and 4-pipe systems (see also pa...

    For example, to prevent excessive noise during the night in hotel rooms, a "stage limitation in night mode" can be set. This means that only the specified fan stage or lower will be used in night mode. When switching to another operating mode all fan stages can still be used. A limitation can be set...
