The optional remote panel makes field wiring between the remote panel and unit easier. Labels are the same for terminals on the remote panel and unit (example: R to R, G to G, etc.). What's more, switches on the remote panel replace the need for someone in the field to provide contacts for fan enable, heat enable and cooling enable. Indicator lights for operation, warnings and alarms are available options on the remote panels. Remote panels fit in NEMA rated enclosures (1, 2, 3, 3R, 4, 4X and 12) for many applications.
