EnergyX
Units equipped with Optional EnergyX have a factory installed energy recovery ventilator (ERV). The ERV is used to pre−condition outside air as it is brought into the rooftop unit. To do this it uses building air and an enthalpy wheel. It can also have a wheel bypass that acts as an economizer to allow free cooling. In Appendix A there are ERV points for display under Outside Air Unit (OAU) menus. These points and ERV specifics are explained in the EnergyXv2 Supplement Installation Instructions contained in the unit’s information packet.
