In the room controller, the sensor is integrated into the housing. For channel controllers, an external sensor is connected. he resistance of the sensor is converted into an actual-value signal (x i ) by a measuring bridge, and is then compared with the setpoint X S. he controller amplifies the control offset and, depending on its type, creates the corresponding output signals: F041, S1/ = OFF: OEN/SO/CLOSED signals (3-point control) for the I control with a motorised drive without a positioner. For heating with changeover to cooling via external signal (C/O) for -pipe system. F041, S1/ = ON: ulse-pause signals (-point control) for control for heating and cooling, for a thermal or continuous actuator for 4-pipe systems, or heating with changeover via external signal (C/O) to cooling for thermal actuator of a -pipe system. F061: Continuous signal for I control for heating and cooling, for a continuous actuator for 4-pipe systems, or heating with changeover via external signal (C/O) to cooling for continuous actuator of a -pipe system. /7 7.3 Right of amendment reserved 015 Fr.

As a result, the average heating output also changes, as well as the stroke of a proportional thermal actuator such as a -controller. / XSd E=0,5 x E=0,50 XSh E=0,75 B01806_de Dead zone changeover (X t ): hus, for the heating/cooling sequence, the dead zone is increased to 4. As a result, the temperature is decreased in heating mode and increased in cooling mode (Eco mode). Setpoint shift (command variable w): he setpoint is increased with respect to the defined value X S with an influence of /V. his can be used, for example, to adjust the room temperature to the increasing outside temperature (summer shift), or to avoid condensation due to rising humidity. Dew point (): Frost-protection function: When the contact of the dew-point monitor is closed, the cooling output becomes inactive or the cooling valve is closed. Independently of the defined setpoint and dead zone, at temperatures < 6 C, the heating valve is opened. If the temperature rises above 7 C, the frost-protection function becomes inactive. If necessary, the temperature must be compensated in order to adhere precisely to the switching points. Summer-/wintertime changeover (C/O): When the contact is closed, the output for heating is switched to cooling.

When actual value x i = setpoint X s : both control units closed Contact X t closed; absence: sequence operating mode (reduced mode). he dead zone is increased and causes a decrease in the heating mode and an increase in the cooling mode.
