NOTE: The 240/24 VAC power transformer has an overload reset button located on its 24 VAC output side (see Figure 3). An overload on the transformer will cause its reset button to pop out disrupting the 24 VAC output to the main control board. Overload reset button must be pressed in to restore 24 VAC output.
