Page 6: Introduction
The DAC’s configuration can be programmed through the E2 front panel. The DAC was designed to be used with a Copeland supervisory controller, and one of these supervisory controllers is the only method for configuring the DAC. If there is no supervisory controller, the DAC can be standalone, but in reduce capacity. -

DAC and the transformer that supplies power to it is not enough to be of concern; however, it is very important NOT to exceed this maximum wire length or the controller will not operate correctly. 026-1727 R5 Discharge Air Controller Manual ©2024 Copeland LP. -
Page 9: The Modbus Network
The DAC uses an RS485 network connection to communicate with E2 site controllers. Wiring Types Copeland specs Belden #8761 shielded twisted pair cables for use as MODBUS wiring (or Belden #82761 and Belden #88761 for plenum installations). -
