Special features: The control system can be used to select 5 ventilation levels PP45-15/20/30/36/42m3/h and PPB 30 - 5/12/18/22/26 m3/h and 3 operating modes: continuous ventilation (with heat recovery), cross ventilation (without heat recovery) and sensor-controlled automatic operation. Continuous ventilation with heat recovery operating mode: PushPull operation. The devices run alternately and change direction every 60 seconds. Cross ventilation operating mode: One device is permanently in supply air mode and the corresponding device in extract air mode (e.g. for summer night cooling). In automatic mode, the flow volume is continuously adjusted to the sensor value (HYI, HY, CO2, VOC). The RLS 45 K room air control system can be expanded with the internal humidity sensor or with the external sensors (humidity, CO2, VOC). The air flow volume is adjusted and the devices achieve energy efficiency class A+. An odd number of devices can be operated. The volume flows are automatically divided according to the number of devices. Time-limited intensive ventilation (shock ventilation) or time-limited shutdown (sleep function) can also be selected at the touch of a button. The RLS 45 K room air control system enables communication between exhaust air devices (e.g. ECA/ER) and PushPull devices. This means that when an exhaust fan starts up, the PushPull devices switch to supply air mode to compensate for the resulting negative pressure. Supply air mode is possible with a run-on time of 0, 6 or 15 minutes. The number of connected devices is also taken into account. The control system has a separate 230V input whose function can be defined in the software. The following functions are available: safety shutdown, sleep function, shock ventilation, supply air function for the exhaust air devices with 0s, 6min or 15min run-on time. ModBus connection is possible. In addition, the RLS 45 K room air control system offers the option of conveniently configuring the device on a PC/laptop (Windows) using commissioning software. Simple, time-saving digital commissioning and creation of digital commissioning protocols and recovery files. The RLS 45 K room air control system in combination with the EnOcean expansion module PP 45 EO offers the unique option of connecting the wired PP 45 K and PP 45 O and the PP 45 RC radio devices. With this control combination, for example, wired devices can be installed on the ground floor and radio devices on the first floor. The entire system is controlled at the touch of a button. The control system can be expanded with additional controls or PP45 LT power units. The room air control system is required as an accessory for the final assembly sets PP 45 K, PP 45 O or PPB 30 K, PPB 30 O. For the PP 45 RC device series, the wired RLS45 K control can optionally be used instead of the DS 45 RC radio switch. The RLS 45 K must then be combined with the EnOcean extension module PP 45 EO. Up to 6 fans can be controlled simultaneously via an RLS 45 K room air control system, e.g. 6 x PP 45 devices or 4 x PP 45 devices + 1 x PPB 30 or up to 3 x PPB 30 devices.Article: RLS 45 K, rated voltage: 230 V, mains cable: 3 / 1.5 mm2, installation location: wall, installation type: flush-mounted, material: plastic, color: pure white, similar to RAL 9010, weight: 0.112 kg, weight with packaging: 0.341 kg, width: 80 mm, height: 80 mm, depth: 49 mm, width with packaging: 81 mm, height with packaging: 81 mm, depth with packaging: 50 mm
