Page 30 Operation and indication | ETS configuration During active permanent manual operation, all incoming telegrams are tracked internally. At the end of manual operation, the outputs will be set to the tracked states or to the positions last set before the permanent manual operation. The individual priorities of the functions with respect to one another are taken into account here.

Operation and indication | ETS configuration ￭ Activate the parameter "Disable bus control of individual outputs" on the para- meter page "Manual operation". The function for disabling the bus control is enabled and can be activated loc- ally. Alternatively, deactivating the parameter prevents disabling of the bus control from being activated in permanent manual operation mode.
Page 32 Operation and indication | ETS configuration status display. If a temporary status indication has been activated by pressing the "Manual operation" button, the object transmits the value "ON". If the object receives a telegram with the value "OFF" or "ON", the status LEDs indicate the status of the outputs according to the display length.

Valve outputs | Priorities for valve outputs Valve outputs Priorities for valve outputs The heating actuator distinguishes between various functions and events, which either affect all of some of the assigned valve drives globally, or only specifically af- fect individual outputs. Because these functions and events cannot be executed sim- ultaneously, there must be priority control.
Page 38: Channel Configuration
Valve outputs | Channel configuration configured in such a way that the starting state should be tracked at the end of this function. Permanent manual operation is now activated. The actuator assumes the command value of manual operation (e.g. 50%). Whilst manual operation is active, service mode is deactivated via the KNX.

Page 40 Valve outputs | Channel-independent functions In addition, valve outputs, which receive preset command values via the data format "Switching (1-bit)" and "Switching (1-byte) with command value limiting value", influence the heat requirement control. In the case of "Switching (1- bit)", an "OFF" command value is interpreted as "0%" and an "ON" command value as "100%".

Page 62 Valve outputs | Channel-independent functions telegram transmission should take place after a device reset or not. After a device reset, the failure signal of the valve operating voltage can be optionally time-delayed with the delay being set globally for all feedback together on the para- meter page "General - Valve outputs".

Valve outputs | Valve output - General Transmit after bus voltage return no / yes The object for the transmission of a failure of the valve operating voltage can actively transmit the feedback information after a bus voltage return and an ETS program- ming operation.
Page 64: Data Formats For Command Values
Valve outputs | Valve output - General 9.4.2 Data formats for command values The heating actuator receives 1-bit or 1-byte command value telegrams, transmitted, for example, by KNX room temperature controllers. Usually, the room temperature controller determines the room temperature and generates the command value tele- grams using a control algorithm.
Page 65 Valve outputs | Valve output - General Valve outputs, which receive preset command values via the data format "Switching (1-bit)", influence the heat requirement and pump control. Here, an "OFF" command value is interpreted as "0%" and an "ON" command value as "100%".
Page 66 Valve outputs | Valve output - General Often, control circuits are subject to non-constant changes in the setpoint presetting (e.g. frost protection, night operation, etc.) or short-time interference (e.g. measured value deviations due to brief opening of windows or doors near the sensor). For the setting of the scanning ratio of the required command value to take place as quickly and correctly in these cases, even with a longer set cycle time, without any negative impact on the reaction time of the control section, the actuator uses a special method...
Page 67 Valve outputs | Valve output - General – Case 3 Command value change, e.g. from 80% to 30% during the opening phase of the valve (opening phase too long) (see figure 10). Before the reception of the new command value (30%), the old setpoint (80%) was active.

Page 69 Valve outputs | Valve output - General does not produce the desired heating reaction, on account of the sluggishness. With sluggish underfloor heating systems, small constant command values (only short switch-on phases of the PWM) frequently do not produce any significant level of heating.
Page 70: Pwm Cycle Time
Valve outputs | Valve output - General Image 14: Example of command value evaluation with limiting value 9.4.3 PWM cycle time The "PWM cycle time" parameter specifies the period length of the pulse-width-mod- ulated output signal of a valve output. It allows adaptation to the adjusting cycle times (the adjusting time it takes the drive to bring the valve from its completely closed to its completely opened position) of the valve drives used.
Page 71 Valve outputs | Valve output - General – Disadvantage: It should be noted, that, due to the full valve lift, the life expectancy of the actu- ators can diminish. For very long cycle times (> 15 minutes) with less sluggish- ness in the system, the heat emission into the room, for example, in the vicin- ity of the radiators, can possibly be non-uniform and be found disturbing.
Page 72: Valve Direction Of Action
Valve outputs | Valve output - General Image 16: Ideal course of the valve stroke for a Cycle time < Adjusting cycle time The continuous flow of water through the valve, and thus the continuous heating of the drives causes variations and changes to the dead times of the drives during the opening and closing phase.
Page 73: Reset Behaviour
Valve outputs | Valve output - General By contrast, switching command values are inverted for deenergised opened valve drives. Example: Command value ON -> Output switched off, Command value OFF - > Output switched on. On the LED status display, the valve direction of action configured for each output in the ETS is not taken into account.
Page 74 Valve outputs | Valve output - General (as would be the case if there was a faulty command value found in the course of command value monitoring)! The actuator only polls the command value preset for emergency operation. ￭ Set the parameter to "Command value as before voltage failure". After bus voltage return, that command value is set at the valve output which was active at the moment of the last bus voltage failure.
Page 75: Valve Output - General" Parameters
Valve outputs | Valve output - General ￭ Set the parameter to "Activate command value according to emergency opera- tion". For the valve output, the actuator polls the emergency operation command value, as configured in the ETS. Here, the active operating mode (summer / winter) is taken into account, providing that a summer / winter change-over is configured.
Page 76 Valve outputs | Valve output - General Valve output Activation with Pulse Width Modulation (PWM) Command value limiting value Pulse width modulation (PWM): Command values are implemented by the actuator with an equivalent pulse-width-modulated switch signal at the valve output. Command value limiting value: The constant command value is converted into a switching output signal, depending on a configured limiting value.
Page 77 Valve outputs | Valve output - General PWM cycle time 0.5 minutes 1 minute 1.5 minutes 15 minutes 20 minutes The "PWM cycle time" parameter specifies the switching frequency of the pulse- width-modulated output signal of the valve output. It allows adaptation to the adjust- ing cycle times (the adjusting time it takes the drive to bring the valve from its com- pletely closed to its completely opened position) of the valve drives used.

Page 82 Valve outputs | Cyclical command value monitoring / emergency operation The configured valve direction of action (deenergised closed / deenergised opened) is taken into account in the electrical activation of the outputs by emergency operation. With deenergised closed valves, the switch-on time is derived directly from the configured PWM and the cycle time.
Page 83 Valve outputs | Cyclical command value monitoring / emergency operation After a device reset (bus voltage return, ETS programming operation), the command value objects first contain the value "0". The state or emergency operation (active or inactive) is saved internally in the device after a bus voltage failure and is restored automatically after a bus voltage return.
Page 84: Command Value Monitoring / Emergency Operation Parameters
Valve outputs | Cyclical command value monitoring / emergency operation As soon as a command value telegram is missing on a monitored valve out- put, and thus emergency operation is activated, then the actuator transmits a fault signal via the object "Command value - Fault - Status" according to the configured telegram polarity.

Page 99 Valve outputs | Short-circuit and overload detection If there is a collective overload, various weak overloads, possibly at multiple outputs, have collected into a stronger overall overload. If there is a collective overload, it may occur that, even after four testing cycles, no output can be clearly identified as over- loaded.
Page 100 Valve outputs | Short-circuit and overload detection Exception: If the previously executed testing operation was the 4th sequence in succession without any error detection, then the actuator will assume that this is a collective overload at multiple outputs. In this case, the actuator will automatically deactivate one output of the affected group (output 3 or output 6), according to the priority.

Valve outputs | Valve rinsing Valve rinsing can optionally be started and, if required, stopped using a com- munication object. If valve rinsing was started by the object, then the actuator will stop the cycle time of the cyclical valve rinsing operation. The cycle time is only restarted after the rinsing operation has been fully executed without inter- ruption or a stop command was received via the object.
Page 110 Valve outputs | Valve rinsing Valve rinsing Checkbox (yes / no) To prevent calcification or sticking of a valve which has not been activated for some time, the actuator has an automatic valve rinsing function. Valve rinsing can be ex- ecuted cyclically or using a bus command, causing the activated valves to run through the full valve stroke for a preset period of time.

Page 121: Room Temperature Controller
Room temperature controller | Channel configuration Room temperature controller There are 12 controllers integrated into the device's software that can be used for in- dividual room temperature control. This allows the temperature to be set in up to 12 rooms or room areas to specified setpoints through independent control processes. The command value outputs of these controllers can be linked to the electronic valve outputs of the actuator, meaning that temperature control and valve activation can take place using just one bus device, if required.

Page 199: Setpoint Temperature Limit, Cooling
Room temperature controller | Setpoint temperature limit, cooling 10.9 Setpoint temperature limit, cooling In accordance with statutory requirements in Germany and elsewhere, the temperat- ure at the workplace should be a maximum of 26 °C, or at least 6 K below outdoor temperatures higher than 32 °C.
Page 200 Room temperature controller | Setpoint temperature limit, cooling A basic setpoint shift never affects an active setpoint temperature limit with dif- ferential measurement to the outdoor temperature. In this case, the setpoint temperature limit only works with the unshifted basic setpoint. A setpoint shift active before the limitation is restored after the limitation, if it was not reset in another way, e.g.

Page 208 Room temperature controller | Scenes Presetting scene numbers and scene operating modes The presetting of the scene number can be defined for each scene of the room tem- perature controller, by which scene number (1...64) the scene is addressed, i.e. called up or stored.
Page 209 Room temperature controller | Scenes The storage function is activated for the scene in question. When a storage telegram is received via the "Scene extension" object, the current operating mode is stored internally. ￭ Deactivate the parameter "storage function" for each scene. The storage function is deactivated for the scene in question.
Page 210: 1Scene Parameters
Room temperature controller | Scenes A scene overflow is not possible. After reaching the last scene of the selected configuration, further ON telegrams of the extended scene recall are ignored. In the same way, the actuator ignores further OFF telegrams if scene 1 was recalled last.
Page 211 Room temperature controller | Scenes With overflow Checkbox (yes / no) The extended scene recall can take place with or without an overflow at the scene limits. An overflow occurs when the last scene of the selected configuration is reached when counting up or scene 1 when counting down and an additional tele- gram in the last counting direction is received by the actuator.
