Unique 33++ 2.2.5 Fireplace Control Circuit
Unique 33++ 2.2.5 Fireplace Control Circuit. Label the voltage v = 25.0 v and the resistances (clockwise from b) r1 = 20.0ω, r2 = 5.00ω, r3 = 10.0ω, r4 = 10.0ω, and r5 = 5.00ω. The fireplace burner is equipped with four thermal sensors that output a logic (1) whenever a flame is present. Input offset voltage input offset current input bias current. Electric fireplace remote controls are proprietary, not universal.
