System information for operators

• System settings are made in the service menu of the RLS 45 K control unit or with the commissioning software.
• The control units can be used to select the operating modes operation with heat recovery, cross ventilation operation or automatic operation (only when the sensor is connected and activated).
• The operating modes and ventilation levels are displayed on the RLS 45 K control unit with LEDs.
• In operating mode cross ventilation (without heat recovery), the ventilation units operate permanently in one direction in supply air or exhaust air mode.
• The 230 V input of the RLS 45 K control unit has a switching contact for additional functions, such as intermittent ventilation, sleep function or overrun (connection by a specialist installer). This additional function is only valid for the ventilation units connected to the respective room air control unit.
• Automatic mode with sensor control only with connected humidity, CO2 or air quality sensor (VOC). Depending on the sensor values measured (H, CO2, VOC), the volumetric flow of the ventilation units is gradually adjusted. The set operating mode of operation with heat recovery or cross ventilation remains active.
• Automatic mode can be switched on or off manually on each control unit.
• If an internal humidity sensor PP 45 HYI is installed in the RLS 45 K, the value of the internal sensor is always used for humidity measurement.
• The filter is changed as required, at the latest after 2 years.
• Cleaning or maintenance may only be carried out by a specialist installer.
