Tjernlund Products, Inc.: DRAFT SYSTEM CONTROL
August 15, 2002
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.
