What is accomplished by adjusting the handwheel on the compensating relay in automatic boiler controls?

• A. Flow regulation
• B. Biasing
• C. Pressure adjustment
• D. Temperature control

Answer: (B)

Adjusting the handwheel on the compensating relay in automatic boiler controls is primarily associated with biasing. This action allows operators to make fine-tune adjustments to the system's response to variations in conditions, which enhances the overall performance and stability of the boiler control system. Biasing in this context means that the relay can be set to affect how the control system responds under specific circumstances, such as deviations from normal operating conditions. This adjustment helps ensure that the boiler operates efficiently and maintains optimal performance levels by compensating for factors that may otherwise disrupt its operation. While flow regulation, pressure adjustment, and temperature control are crucial aspects of boiler control systems, the specific function of the compensating relay's handwheel adjustment is to modify the biasing of the system, thereby influencing its control characteristics rather than directly affecting these other parameters.
