Cooling in summer operation (from firmware version 1.3.0)

Conditions for cooling in summer operation

• Ventilation units with bypass

The bypass opens automatically when

• the heat register locking time has expired,
• Temperature of room (room sensor configuration) > Temperature of room max. and
• Temperature of outside air > 5°C and temperature of supply air > temperature of SA min.

The bypass remains permanently open as long as all conditions are met. After closing the bypass, the heat register is locked (the control system of the heat register is blocked for the timer duration).
