Resideo offers a complete range of relays for all your residential HVAC applications that are sure to win the race. All relays products are designed to exceed safety and industry life cycle standards. In order to meet these criteria, a statistically significant sample of relays are tested to failure and to our stringent qualification requirements. This testing methodology enables Resideo to verify that relays will exceed industry standards.
