Before adding a hard start assist to an air conditioning condensing unit to start a compressor, make sure the capacitor is good.
Most time delays are measured in seconds that can be manually adjusted or has a fixed set point in its circuit board. Some time delay relays are on-make (time before system starts when power is called) or on-break (time after system shuts down before it can operate again).

There are air conditioning controls that can be added to the system, that are not OEM, to control the operation to come on or shut off when certain situations occur. These include time delays, pressure and temperature controls and compressor start assists.
