The Universal Control Model UC1 is the new standard interlock control for the company’s full line of power venters, draft inducers, and combustion air in-forcers. Features include adjustable pre- and post-purge, LED status/diagnostic indicators, and 10-second prover switch delay to avoid burner startup and wind-induced short cycling, says the company. It interlocks with any 24-120 VAC burner control circuit and includes a “dry” contact actuation option, the manufacturer states.
