Passport I/O Environmental Control

The Passport I/O display has the same look and feel as the old Passport II but with a few new features. Both the Passport I/O and Elite digital controls work with the new Passport I/O circuit board, which utilizes state-of-the-art SMT technology; the software logic is in the displays rather than on the circuit board.

Features of the Passport I/O include: an electric heat relay so electric heat is now a convenient option with DX units; and a new programmable parameter allowing the seawater pump to be set for continuous operation, or to cycle with the compressor. The I/O circuit board has an additional air sensor connection, so the customer can now use the remote air sensor in the cabin and still monitor outside air temperature.

Passport I/O Retrofit Kits are also available.
