Understanding Heat Sequencers

What is the primary function of a heat sequencer in air handler applications?

• To control the temperature of the room

• To manage the operation of the fan and electric heat strips

• To regulate the flow of air through the ducts

• To monitor the energy consumption of the system

How does the heat sequencer activate the electric heat or motor?

• By manually switching it on

• By moving a plunger forward with low voltage power

• By applying high voltage power directly

• By using a thermostat

What is a common issue that can occur with heat sequencers?

• They can overheat and cause a fire

• They may fail to apply power to the terminals

• They can cause the fan to run continuously

• They may produce a loud noise during operation

Why is it important to stage the heat and blower in a heat sequencer?

• To ensure the system uses less energy

• To increase the lifespan of the blower

• To reduce noise levels in the system

• To prevent cold air from blowing through the ducts

What voltage is typically used to operate a heat sequencer?

• 120 volts

• 240 volts

• 12 volts

• 24 volts
