Flexible Installation and Compatible Controls
This HRV stands out for its unique configuration with 5-inch oval ports on the top. Indeed, this design makes it easier to connect in tight spaces where standard round ducts would be difficult to pass. This ensures that the device integrates seamlessly into your ventilation system. That’s why it’s fully compatible with advanced controllers like the STS2.0 touchscreen or the EDF8 electronic model. These controls allow you to manage ventilation and recirculation at your fingertips.
Reliability and Solid Warranty
It should be noted that the robustness of the components defines the HE series from Direct Air. In this regard, the heat recovery core comes with a limited lifetime warranty, proof of its durability. In addition, the engines are protected for a period of 7 years, and the other parts for 5 years. Finally, choosing the PHRVR104 means opting for peace of mind in the long term.
