The Time Delay Relay makes it possible to accurately time the water heater's production of hot water to match the point that you need it.

The Time Delay Relay uses a simple mechanical process to delay the energizing of a compressor. It delays the turn-on of the air conditioner by the selected period of time, which allows the indoor coil to reach it's proper operating temperature before turning on the outdoor compressor. By using this relay when installing an Air Conditioning System, overheating problems may be reduced, and system reliability increased.

This 1-day electric time delay relay allows you to control when a fan unit will run. Perfect for cooling or heating a room, as well as humidifying, the user can program it to start heating or cooling at any hour from 1 second to 30 days from now!

The Rheem 42-21593-03 Time Delay Relay is an AC part, which fits into the 42 series furnace. The relay helps turn the fan off and on when there is no call for heat or cooling.

The time delay relay helps you set the exact temperature to turn on your water heater.
