The S350AA-1C includes an SPDT output relay and three field-adjustable settings: offset (de-energize stage action from set point), heating or cooling mode selection, and differential. The Fahrenheit-scaled dial makes it straightforward to configure for the target application without unit conversion. This module is installed by HVAC technicians working on commercial or light commercial temperature control systems that require sequential staging beyond a single-stage controller.\u003c\/p\u003e\u003cp\u003eThe S350AA-1C is used in conjunction with the A350, A350E, A350P, and A350R series temperature controls. When paired with a Y350R, up to nine S350AA-1C modules can be added to an A350, A350E, or A350R controller via the 5-pin plug-together connector. When used with an A350P and a Y350R, up to four S350AA-1C modules can be added. Using an external transformer rated at 40 VA or greater with an A350P allows up to nine S350AA-1C modules to be connected, supporting large multi-stage systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSPDT output relay provides reliable stage switching\u003c\/li\u003e\n\u003cli\u003eFahrenheit temperature scale for direct field configuration\u003c\/li\u003e\n\u003cli\u003eAdjustable differential for fine-tuned stage control\u003c\/li\u003e\n\u003cli\u003eSelectable heating or cooling mode of operation\u003c\/li\u003e\n\u003cli\u003eAdjustable offset setting for de-energize stage action from set point\u003c\/li\u003e\n\u003cli\u003e5-pin plug-together connector for clean daisy-chain installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with A350, A350E, A350P, and A350R series temperature controls.

Power down the control system and disconnect the transformer before connecting or disconnecting the S350AA-1C module. The 5-pin plug-together connector must be fully seated to ensure proper communication and relay operation. Follow all applicable local codes and the A350-series controller documentation when configuring staging sequences.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Relay\u003c\/strong\u003e: SPDT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Scale\u003c\/strong\u003e: Fahrenheit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustments\u003c\/strong\u003e: Offset, Mode (Heating or Cooling), Differential\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type\u003c\/strong\u003e: 5-pin plug-together\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.40 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: United States\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: JOHNSON CONTROLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: S350AA-1C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JOHNSON CONTROLS","offers":[{"title":"Default Title","offer_id":67631513207090,"sku":"S350AA-1C","price":138.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/187198523.jpg?v=1790448026","url":"https:\/\/voomisupply.com\/products\/johnson-controls-s350aa-1c-temperature-stage-module","provider":"Voomi Supply","version":"1.0","type":"link"}
