Used in numerous electric furnace and heat strip applications. Verify equipment model number, sequencer timing, and terminal configuration before ordering.
On a typical electric furnace, the blower motor is hooked to terminals M1 & M2 (perhaps referred to as H1 & H2 on other various sequencers). The heating elements are then hooked to M3-M4 and M5-M6 and M7-M8, (25 Amp Load) do not over power by connecting more than 1 element per switch
24V feeds the bottom (gold) terminals of the sequencer. Welded jumper bars connect the 24V from one tower to the next. If your application does not use these jumpers, simply twist them off with a pliers. 
Not all the terminals of the sequencer may be used in your application. In some cases, you may need extra terminals. If that happens, included are extra terminal adapters to convert one terminal to two.
