Universal Control - Model UC1
Universal Control:
The UC1 is the new standard interlock control for Tjernlund`s full line of Fixed Speed Power Venters, Draft Inducers and Combustion Air In-Forcers. It can be interlocked with virtually any burner control circuit.
Features include:
- Adjustable pre & post purge,
- LED status / diagnostic indicators,
- 10 second prover switch delay to avoid burner start up and wind induced short cycling.
- Interlocks with any 24-120 VAC burner control circuit and also includes “dry” contact actuation option.
- Selectable voltage eliminates false activation by burner control circuits.
- After each burner cycle the UC1 will continue to operate in post-purge mode to allow the venter to purge the heater and vent of residual flue gases.
- A factory post-purge time is set at 2 minutes and is adjustable up to 16 minutes.
