Understanding Furnace and Thermostat Systems

The video tutorial addresses furnace short cycling issues, explaining the replacement of an Aquastat with a Hydrastat and the importance of thermostat settings. It covers how to calculate amperage using a clamp meter and the significance of voltage testing. The tutorial also discusses managing pressure in the system to prevent fluctuations in room temperature.

What issue was the narrator experiencing with the furnace system?

• The furnace was short cycling.

• The furnace was making loud noises.

• The furnace was overheating.

• The furnace was not turning on.

What type of thermostat does the narrator prefer?

• Smart thermostat

• Programmable thermostat

• Digital thermostat

• Old mercury type thermostat

What is the purpose of the heat assessor in the thermostat?

• To increase the room temperature

• To prevent overshooting the heating

• To decrease the room temperature

• To control the fan speed

How do you calculate the amperage for the hydrostat?

• Multiply the amperage by 2

• Divide the amperage by 1.2

• Add 1.2 to the amperage

• Multiply the amperage by 1.2

What tool is recommended for measuring amperage?

• Clamp meter

• Digital thermometer

• Pressure gauge

• Voltage tester

What should the voltage reading be between when testing the hydrostat?

• 24 and 30 volts

• 50 and 60 volts

• 10 and 20 volts

• 32 and 40 volts

What is the normal pressure range for the boiler system?

• 20 to 30 psi

• 12 to 20 psi

• 10 to 25 psi

• 5 to 10 psi

What is the purpose of the auto water feed in the boiler system?

• To increase the water temperature

• To control the water flow

• To maintain the water pressure

• To decrease the water temperature

What is the difference between a 4,000 count and a 6,000 count clamp multimeter?

• 4,000 count measures DC current only

• 6,000 count measures AC current only

• 4,000 count measures AC current only

• 6,000 count measures both AC and DC current

What is the correct way to use a clamp multimeter for measuring current?

• Place the clamp on the wire without wrapping

• Wrap the wire around the clamp 10 times

• Place both wires through the clamp

• Wrap the wire around the clamp 5 times
