Both models have built in BACnet
low ambient fi rmware that extends the lower starting temperature limit to -25°F.
FOR COMPLETE ERV INSTALLATION YOU WILL ALSO NEED:
• Standard Installation and Operation Manual for the ERV – physical installation and duct connection,
maintenance procedures, etc.
• Supplemental Wiring Schematic Manual – complete unit wiring diagrams.
• User's Manual ACS320 Drives or Users Manual ACS355 Drives – ABB's user's/installer's manual.

RISK OF FIRE, ELECTRIC SHOCK, OR INJURY. OBSERVE ALL CODES AND THE FOLLOWING:
1. Before servicing or cleaning the unit, switch
power off at disconnect switch or service panel
and lock-out/tag-out to prevent power from
being switched on accidentally. More than one
disconnect switch may be required to
de-energize the equipment for servicing.

NOTE: VFD(s) in this unit can be operated in many ways. This Manual provides only an outline of common methods.
DO NOT OPERATE VFD IN CONDITIONS OUTSIDE OF TEMPERATURE LIMITS. The manufacturer's normal
ambient temperature limits for ACS320 VFDs are 14°F to 122°F. RenewAire has worked with the manufacturer
to implement low-ambient-start fi rmware for the ACS355+N831 that extends the lower temperature
limit for starting the VFD down to -25°F, which has been validated by manufacturer and RenewAire testing.
The manufacturer recommends that the VFD not be operated for prolonged periods at temperatures below
14°F to ensure longevity of the VFD. RenewAire commercial ERVs are VFD ready, in extreme climates
consider fi eld installing VFDs in a climate controlled indoor electrical cabinet.
