Function settings General To make function settings, you need to be on the expert level (refer to page 17). Change these settings only if you are fully aware of their impact. Wrong settings can impair or even disable plant operation. Buzzer volume The volume of the buzzer (piezzo loudspeaker) integrated in the central apartment unit can be adjusted to suit individual needs (0..100%).
Apartment Enable setpoint limitation This defines whether setpoint limitation of the room temperatures is basically disabled or enabled. Only when setpoint limitation is enabled does the central apartment unit respond to the setpoint limitation signals received over the wired bus. Main menu > Apartment > Settings > Setpoint limitation: Factory setting Your setting Enabled Disabled Enabled Limitation setpoint This defines the maximum permissible room temperature setpoint (0..
Economy increase The Economy room setpoint for heating all rooms is raised depending on the composite outside temperature. The increase at low outside temperatures (e.g. end point -15 °C) is greater and negated at higher outside temperatures (e.g. starting point -5 °C). This way, long heating up times when changing from Economy to Precomfort or Comfort setpoint can be prevented at low outside temperatures.
If 1 room unit and 2 room temperature sensors are used, the average value of the 2 room temperature sensors is determined first. Then, the actual value of the average room temperature is calculated based on the percentage proportion set for the room unit and the room temperature sensor. When 2 room temperature sensors are used, the average value of the 2 sensors is delivered. The proportion of the individual sensors cannot be changed.
even if the room temperature is sufficiently high. It is accepted that in such cases the room might get overheated. Main menu > Rooms > Room X > Room settings > Min valve pos comf: Factory setting Your setting 0% H/C changeover locking time Changeover locking time prevents heating mode from changing to cooling mode (and vice versa) too quickly and too frequently. This means that when changing over, heating or cooling mode is disabled.

Valve position temperature request On / Off If ”Temperature request winter operation“ is set to “Switching“, the central apartment unit checks the averaged valve position of the respective room group. If the averaged valve position lies above the value set for “Valve position temp request On“ (1..30%), the heat request is forwarded to heat generation. If the averaged valve position lies below the value set for “Valve position temp request Off“ (1..30%), the heat request to heat generation is suppressed.
Integral action time Tn You can set the primary controller’s integral action time Tn for each room group depending on demand (0..600 s).
P-band Xp indoor air quality A P-controller is used to ensures that the indoor air quality is maintained at the required setpoint. The controller’s P-band (0..2000 ppm) can be set here. Within this range, all available stages are switched on and off. Main menu > Ventilation > IAQ controller > P-band Xp: Factory setting Your setting 400 ppm Humidity limitation This function monitors the relative humidity of the air and compares it with the set ”Humidity limit value“.
Switching differential of humidity limitation If the ventilation system was switched on because humidity in the room was too high, it is switched off again when humidity drops below the “Humidity limit value“ by the switching differential set here (1..20%). Main menu > Ventilation > Humidity limitation > Switching diff: Factory setting Your setting 5% Running time humidity limitation The humidity limitation interval starts with the running time set here (0..720 min).
Minimum operating time night cooling If all switch-on conditions for night cooling are met, it is switched on for at least the period of time set here (0..720 min). Main menu > Ventilation > Night cooling > Operating time min: Factory setting Your setting 30 min Reference room night cooling To be able to determine the necessary temperature differential, the central apartment unit requires the room temperature plus the outside temperature.
Startup delay The startup delay (00.00..60.00 mm.ss) prevents the individual ventilation stages from switching on too quickly. Each time a stage is switched on, the delay time must elapse before the next stage can be switched on. Main menu > Ventilation > Ventilation settings > Startup delay: Factory setting Your setting 00.00 mm.ss Locking time After switching off, each ventilation stage remains locked for the period of time set here (00.00..60.00 mm.ss).
Main menu > DHW > Legionella function > Legionella setpoint: Guide value Your setting 70 °C Legionella protection frequency Decide and set how often the legionella function should be activated. It can be performed daily or weekly. With the weekly legionella function, the weekday can be selected (Mo..Su). When using setting “Never“, the legionella function is always deactivated.
DHW priority With DHW priority, preference can be given to DHW storage tank charging by reducing the amount of heat delivered to the heating circuits. No priority During DHW heating, there is no restriction with regard to the amount of heat delivered to the heating circuits. The highest temperature request (space heating or DHW) is forwarded to the heat demand controller. Absolute priority During DHW heating, the heating circuits are not allowed to draw any heat.
Forced charging Normally, DHW storage tank charging is started only if the storage tank temperature drops below the switch-on point (DHW storage tank setpoint minus switching differential). Forced charging can enforce storage tank charging, even if this switch-on criterion has not been reached. Starting If forced charging is activated and the storage tank temperature lies at least 1 K below the normal setpoint, forced charging is started. Ending Forced charging is ended when the normal setpoint is reached.
System pump required 3131S59 If the system pump is controlled by a KNX TP1-compatible controller, it can be selected whether the system pump should run during DHW charging (depending on the selected type of plant). A Case A Case B B System pump required for DHW charging (system pump: Yes) System pump not required for DHW charging (syst.
Switching groups Scene number The scenes defined during commissioning automatically is numbered (1..16). To prevent scene numbers from overlapping with other existing scene buttons (e.g. GAMMA wave or Hager tebis), or to provoke them, the scene numbers of the central apartment unit can be changed, if required.
Time of day / date Summer time start / winter time start The change from summer time to winter time, and vice versa, takes place automatically. The earliest changeover date can be adjusted should the relevant standards change. As a result of the dates set for the change from winter time to summer time, or vice versa, the time of day on the first Sunday after that date is brought forward from 02:00 ( winter time) to 03:00 (summer time), or set back from 03:00 (summer time) to 02:00 (winter time).
Inputs / outputs Simulation of outside temperature For test purposes, outside temperatures of between -50 and 50 °C can be simulated on the central apartment unit. In that case, the measured value of the outside sensor is overridden. The simulated outside temperature is also used for the composite and the attenuated outside temperature. During the time simulation is active, fault status message “Outside temperature simulation active“ is displayed. Simulation must be manually reset (setting ---).
