It can operate as a standalone controller or be integrated with AAON's VCB-X or VCCX2 controllers, exchanging signals over an E-BUS via a modular expansion cable and the host controller's expansion port. Key capabilities include second-stage reheat when two hot gas reheat valves are used, reheat solenoid valve control, and coil flushing to promote refrigerant oil return. The MHGRV-X features a 2×8 LCD display housed in a plastic enclosure, mounting via three base holes, and is designed for mounting in environments free from extreme temperatures or moisture. Electrical power input is 18–30 VAC with a maximum power draw of 18 VA; operating temperature range is -30°F to 150°F and 0–95% relative humidity (non-condensing). Weight is about 1 lb. In stand-alone or integrated configurations, it communicates essential controls such as reheat enable, supply-air temperature setpoint, and reset commands between the MHGRV-X and the host controller, enabling coordinated dehumidification performance in AAON packaged units or systems that use the MODGAS-X family. \u003c\/p\u003e\u003c\/div\u003e","brand":"AAON","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51656684273966,"sku":null,"price":725.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_01285b0a-7e63-46f7-8a12-ef705f2647e3.jpg?v=1769462699","url":"https:\/\/plgautomation.com\/products\/aaon-oe377-26-00059-mhgrv-x-controller-system","provider":"PLG Automation ","version":"1.0","type":"link"}
