{"product_id":"446-157","title":"446-157","description":"This Honeywell Relay Center serves as a vital switching hub for boiler and hydronic heating systems. Designed to bridge the gap between low-voltage thermostat controls and high-voltage HVAC components, this relay allows a 24V signal to safely and efficiently operate 120V equipment such as circulator pumps and burner motors. Featuring a Double Pole Single Throw (DPST) configuration, it provides reliable electrical switching for residential and light commercial heating applications. If your boiler is failing to trigger the pump or the burner isn't responding to your thermostat's call for heat, replacing the relay center can restore proper system communication and home comfort. Built for durability and long-term performance, this transformer relay center is a standard component for modernizing or repairing hydronic heating controls.\u003cbr\u003e\nType: HVAC Relay Center \/ Transformer Relay\u003cbr\u003e\nSize: Medium\u003cbr\u003e\nApplication: Used in hydronic heating systems, boilers, and HVAC installations to control line-voltage circulator pumps and burners from a low-voltage thermostat signal.\u003cbr\u003e\nSpecifications: Primary Voltage: 120V AC; Control Voltage: 24V AC; Switch Type: DPST (Double Pole Single Throw); Frequency: 50\/60 Hz; Integrated transformer included","brand":"BCFurnace","offers":[{"title":"HONEYWELL RELAY CENTRE 120V DPST 24V RELAY BOILER \/ 446-157","offer_id":48734565695773,"sku":null,"price":398.1,"currency_code":"CAD","in_stock":true},{"title":"HONEYWELL RELAY CENTRE 120V DPST 24V RELAY BOILER \/ RA832A1082","offer_id":48734565761309,"sku":null,"price":398.1,"currency_code":"CAD","in_stock":true},{"title":"HONEYWELL RELAY CENTRE 120V DPST 24V RELAY BOILER \/ RA832A1082\/U","offer_id":48734565728541,"sku":null,"price":398.1,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/c4e221d9ef37421e888d90dafa7f0c94.webp?v=1773959405","url":"https:\/\/bcfurnace.myshopify.com\/products\/446-157","provider":"BCFurnace","version":"1.0","type":"link"}
