Comfort Humidity and Timer Control Board for LUNOS Silvento (5/FK)

The Comfort humidity and timer board 5/FK is one of the three control boards that can be used to control the fans in the LUNOS Silvento EC series.

This selection of different volume flows for basic ventilation and demand ventilation is possible: 0 / 15 / 20 / 30 / 40 / 45 / 50 / 60 / 100

The specified volume flow rates refer to the installed condition with accessories (ducting, weather protection, roof cowls, grilles).

The actual volume flow rates can be set manually or by software to the setting values of the board. In this way, deviations of the actual volume flow rates from the target volume flow rates can be reliably compensated by individual conditions.

Automatic Humidity Control

The fan continuously records absolute humidity and calculates a moving average as a background reference, representing the lowest humidity level achievable through active ventilation. This prevents unnecessary continuous operation, such as during periods of high outdoor humidity in summer. If indoor humidity rises temporarily by at least 5% above this reference (for example, during showering), the fan will activate humidity-controlled operation when enabled via the DIP switch.

The Comfort Humidity and Timer board has the following functions:

• Stepless comfort humidity-temperature control
• Time delay: adjustable to 0, 15 or 30 minutes
• Interval switching: 30 minutes demand ventilation every four hours, or 15 minutes demand ventilation every two hours
• Switch-on delay: adjustable to OFF, 45 or 120 seconds
• Slot for an additional module:
• Radar-supported motion detector (5/BM)
• Diagnostic cable
• Filter change display
