Engineered Air EngA Remote Control Panel – For DJ-40-0 HVAC System, 24V Control, 1-Phase, CSA Certified

Condition: New, old stock. Never installed. Includes original labels. Physically intact with visible wear consistent with lengthy storage, see pictures for more info. Sold as a standalone control component.

This is a Remote Control Panel manufactured by Engineered Air® (EngA®), a division of Airtex Manufacturing Partnership, located at 1175 Twinney Crescent, Newmarket, Ontario. The panel is certified as a control component of Engineered Air model DJ-40-0, which is part of a line of custom-built HVAC rooftop units and air handlers designed for commercial and industrial air distribution.

The control system operates on a 24V control circuit, single-phase, 60Hz, and is designed to interface with larger systems, such as gas-fired make-up air units or ventilation equipment. The control box is CSA certified (label #34974) and includes components potentially marked or supplied by Hydel Engineering (label E863), commonly associated with certified electrical enclosures in HVAC.

This unit is not a standalone HVAC control board but rather a remote control interface, typically used for thermostat input, fan cycling, unit status indicators, or control overrides in field-installed systems.
