Exhaust air system - A80ec DIN 18017-3 - decentralised ventilation

You can ventilate moisture-intensive rooms such as bathrooms, toilets or kitchens effectively with our powerful decentralised ventilation unit A80ec extract air system. The fan converts volumes of 15 – 90 m³/h (depending on the control board) and thus ensures a balanced air and moisture balance in your exhaust air rooms. Various setting options allow individually adapted activation and running performance. The A80ec is operated and controlled with one of the two available boards. The extract air fan (decentralised ventilation A80ec extract air system) is suitable for use in interior rooms according to DIN 18017-3. By using the optional second room connection, up to 2 rooms (in a 1/3 to 2/3 ratio) can be vented.

3 mounting variants are available:

• Surface mounting
• Flush mounting
• Use as a shaft ventilator

2 control boards in 2 versions are available for the A80ec:

Standard control board up to 60 m³/h (volume flow control in steps, time delay, interval switching, switch-on delay).
Standard control board up to 90 m³/h with second room connection (volume flow control in steps, time delay, interval switching, switch-on delay)
Comfort control board up to 60 m³/h (with humidity sensor, infinitely variable volume flow, time delay, interval switching, switch-on delay)
Comfort control board up to 90 m³/h with second room connection (with humidity sensor, infinitely variable volume flow, time delay, interval switching, switch-on delay)

Control board with humidity sensor enables humidity-controlled operation. If the control board does not have a humidity sensor, the interval circuit with demand ventilation can be set via DIP switch.

When using the second room connection, the corresponding board must be selected (decentralised ventilation A80ec extract air system).

The A80ec has various control options:

Basic and demand ventilation adjustable in steps via DIP switch on circuit board.

Run-on time adjustable: 15 min. or 30 min.
Interval switching: every 4 hours with 30 min. running time in demand ventilation stage
Interval switching: every 2 hours with 15 min. running time in demand ventilation stage
Switch-on delay: 45 sec. / 120 sec.>

Possibility of integrating a switch with single or double rocker. When the switch is actuated, the A80 switches to demand ventilation. Combination with room lighting (presence) possible.

When a control relay is integrated, the S160 systems are switched off when the A80ec is switched on and used as downstream elements (decentralised ventilation A80ec extract air system).
