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 O room air control can be expanded with the internal humidity sensor or with the external sensors (humidity, CO2, VOC). The delivery volume is adjusted and the devices achieve energy efficiency class A+.Operation of an odd number of devices is possible. The volume flows are automatically divided according to the number of devices.Modbus connection possibleThe control can be expanded with additional controls or PP45 LT power unitsRecommended for use of the devices in wind-exposed and noisy areas. Using the reveal element increases the standard sound level difference value by 3-9 dB. With the additional PP45 LEW90 angle piece, the standard sound level difference value can be increased by a total of 9-13 dB. Fire protection class B1. A reveal element is required as an accessory for the final assembly sets PP 45 K, PP 45 O and PP 45 RC when installed in the window reveal. The outer cover of the reveal duct is made of brushed stainless steel.Article: PP 45 LE, Installation location: External wall, Material: EPP plastic, Housing material: EPP plastic, Outer cover material: Stainless steel, Color: Brushed stainless steel, Weight: 1.296 kg, Weight with packaging: 1.383 kg, Fire protection: Fire protection class B1, Width: 100 mm, Height: 400 mm, Depth: 661 mm, Width with packaging: 105 mm, Height with packaging: 405 mm, Depth with packaging: 700 mm
