Relays of this type switch load circuits on and off in response to a low-voltage control signal, allowing thermostats, controllers, or other switching devices to operate higher-current loads without direct contact. Licensed HVAC technicians and plumbers install units like this as part of control system assemblies, zone valve wiring, or auxiliary switching applications. The compact housing measures 2.0 inches in length, 1.85 inches in height, and 1.69 inches in depth, making it suitable for installations where panel space is limited.\u003c\/p\u003e\u003cp\u003eThe MARS 164 relay is intended for residential and light commercial HVAC and plumbing control applications. It fits into control panels, zone control boards, and auxiliary switching setups where a reliable switching relay is required. Its compact footprint allows installation in tight enclosures or alongside other control components without requiring significant additional space.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCompact form factor at 2.0 x 1.85 x 1.69 inches for space-limited installations\u003c\/li\u003e\n\u003cli\u003eDesigned for use in low-voltage HVAC and plumbing control circuits\u003c\/li\u003e\n\u003cli\u003eFunctions as a switching relay to isolate control signals from load circuits\u003c\/li\u003e\n\u003cli\u003eSuitable for zone control, auxiliary switching, and system control panel applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement relay for residential and light commercial HVAC and plumbing control system applications requiring the MARS 164 relay configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified plumber familiar with low-voltage control wiring. De-energize the system and verify power is off at the disconnect before handling any control components. Follow NEC guidelines for low-voltage control wiring and ensure all connections are secure before restoring power. Do not exceed the relay's rated electrical specifications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.85 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.69 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 1.69 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 685744191643\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RECTORSEAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: M19164\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51383542776114,"sku":"M19164","price":52.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670887.png?v=1782599973","url":"https:\/\/voomisupply.com\/products\/rectorseal-m19164-mars-164-relay","provider":"Voomi Supply","version":"1.0","type":"link"}
