How to Wire an Air Conditioner for Control 5 Wires Easy Best advice, call an HVAC company and get them to wire it correctly. As far as the Y wire, it does not have to connect to the furnace control board for the AC to work. Many times, the Y will go straight to the condensing unit many times via the furnace or air handler where it is coupled with the C or common for a complete circuit for condenser control. Reply. Wayne on February 22, 2020 at 12 ... What Causes Voltage Drop and How to Deal With It HVAC School The voltage drop across a wire can ONLY be measured under load, simply measuring the potential at the end of a circuit without it being under load tells you almost nothing because the circuit is open. The voltage drop measured is equal to the percentage of the total circuit resistance being measured across. In other words… if the total applied voltage at the main panel is 240V and you are ... HVAC Low Voltage Troubleshooting Aztilac HVAC units are very sensitive to electricity voltage. If the voltage is too high, and the circuit breaker does not trip, it can cause the system to fry. Similarly, if the voltage is low, the unit has to work harder, and this can cause it to overheat. It is clear that for efficient working and optimum output, the HVAC unit should get adequate voltage as is required. Anything more and anything less is not acceptable. Today, we shall concentrate our efforts on understanding the causes of low ...
