Night-time cooling / flush mode

Parameters: Night-time cooling / flush mode

Set value dependent on ventilation unit type → Volumetric flow of ventilation level.

Volumetric flow specification for the night-time cooling and flush mode functions.

Night-time cooling

Activation possible using week time program and sensor input. (Note configuration for sensor inputs). Fan operation can be adjusted using specified air volume (max. 100 % possible). Bypass opened if

• T room reference> maximum room temperature and
• T supply air > minimum supply air temperature,
• T outside air > 5 °C,
• Timer for supplementary heat register bypass lock elapsed.

Display note: Night-time cooling active.

If the temperature conditions mean that cooling is not possible, fan operation is interrupted for 50 min. After this time, a further attempt is made at cooling (10 minute fan operation).

Flush mode

Unit is operated with the volumetric flow set by the user, e.g. max. air volume replacement in defined time frame. Activation possible using week time program and sensor input (note configuration for sensor inputs). Fan operation can be adjusted using specified air volume (max. M³/h possible).

Display note: Flush mode active.
