Receiving
Upon receiving the product, check that all items are accounted for by inspecting against the receipt or bill of lading. This
system ships in multiple packages along with any additional accessory items on the order. Alert the carrier if any dam-
age is detected to any of the items. The customer shall make note of shortage of items or damage to any items within the
delivery receipt. Copies of the bill of lading shall be signed by the carrier. If items are damaged, immediately contact your
manufacturer’s representative. Any physical damage to the equipment after acceptance is not the responsibility of the
manufacturer.
System Overview
Control System
The DOAS system is controlled by an Aurora System controller, ASC, which resides in the ERW cabinet when exhaust air
energy is required. In applications without exhaust air energy recovery, the ASC resides inside the heat pump, FAV. For
more detailed controls information please refer to ICM2701EW.
Frost control
If preheat is needed for the application, a 24 VAC output signal is provided from the Aurora System Controller. A preheat
temperature limit is configurable in the controller so that the preheat output is activated once the outdoor air drops below
this setpoint.
DAS System
CAUTION
WARNING: Before performing service or
maintenance operations on a system, turn
off main power switches to the indoor unit. If
applicable, turn off the accessory heater power
switch. Electrical shock could cause personal
injury.
