Example 2

This second example (Figure 9) shows a control board that does not provide a 

common wire screw terminal. In this example, an additional length of wire was added to the 

resistor which allowed it to connect from the ‘W’ terminal to the connector for the 24V com-

mon that connects from the HVAC transformer to the control board.

When the bypass resistor is in place, you should re-assemble any covers or housings that 

were removed to access the transformer and control panel (often, safety switches prohibit 

the HVAC equipment from running until all covers are in place).

Restore power to the HVAC system and test that both heating and cooling are functioning 

correctly with the resistor in place.
