VAILLANT Package 4.3506 aroTHERM plus
2-unit cascade VWL 125/6 A S2
Package includes (2 pcs.):
VAILLANT heating heat pump
aroTHERM plus VWL 125/6 A S2
(Air/Water)
Product advantages:
- High flow temperatures for
modernization
- Modulating compressor with
inverter technology constantly adapts output
to the actual building heating load
- Actively integrated cooling function as standard
- SoundSafeSystem for particularly quiet
operation
- Can also be integrated into an existing heating system
- Can be operated in a hybrid system bivalently
alternatively, in parallel, or with the
triVAI parameter
- Intelligent use of
self-generated energy (PVready)
- Integrated R290 safety concept
Features:
- Modulating EC fan
- High-efficiency pump
- Sensor-controlled refrigerant circuit
- Safety heat exchanger (double-walled)
- Automatic vent valve
- Integrated active cooling operation
(for this, the heating system must be prepared on-site
and a
coding resistor must be used)
