    ZHK NANO In the night setback mode, the rooms can be cooled with the cool outdoor air outside normal work- ing hours; all heating batteries, cooling batteries, recovery systems, humidity and air quality control are disabled. The setting is made in the menu Night setback, which can be entered directly.

    ZHK NANO Speed control Similar to the airflow rate control the speed for economy, comfort and night setback mode can be set. The fans are operated at the set speed, regardless of airflow rate or duct pressure.

  • Page 12: Supply Air

    ZHK NANO Return air cascade (RetCasc) The return air temperature is used as a control variable. The supply air setpoints for the heating batteries and cooling batteries are calculated by the deviation between the current return air tem- perature and the setpoints.
  • Page 13 ZHK NANO fluctuations. The limiting function of the supply air tries to limit the battery power to comply with the specified minimum and maximum values. A dead zone can be defined between the setpoints for heating and cooling, by which a deactivation of the heating batteries and cooling batteries can be achieved (energy saving).
  • Page 14 ZHK NANO 14.2.2 AHU with 3 batteries (saturation temperature) If the device has a preheating battery, a cooling battery and a postheating battery, then a satura- tion temperature sensor can be mounted after the cooling battery. By this sensor, the first two bat- teries can be controlled, whereby the setpoint for this measurement point is lowered at a dehumidi- fication requirement.

In case of a higher supply air humidity (corresponds to the fresh air humidity in the fresh air mode), it is switched to recirculated mode as a function of the de- humidification requirement (see chapter 14.2.6 for more information), in order to not increase the...
